10 Plastic Bottle STEM Projects for Kids: Fun Ways to Learn & Recycle

*We’re an affiliate – we may earn a commission through qualifying purchases from the links on this page. As always, thanks!*

Plastic bottles.  They’re everywhere.  More than one million plastic bottles are sold every minute worldwide . That’s a lot of bottles. About 1,440,000,000 per day.  In the United States, only 30% of plastic bottles are recycled.  Much of the rest make their way to landfills or the oceans. 

We can do better with some plastic bottle STEM projects.  STEM projects with water bottles can be fun and easy to do, and we give the bottles another life by recycling (or upcycling) through activities.  Let’s explore!

Balloon Inflation with a Plastic Bottle DIY Plastic Bottle Rocket Wind Spinner from a Plastic Bottle Tornado in a Bottle DIY Plastic Bottle Lava Lamp Sensory Bottles Plastic Bottle Shaker Self Watering Planter Made from a Plastic Bottle Ecoshpere in a Plastic Bottle Air Pressure and the Empty Plastic Bottle

Balloon Inflation with a Plastic Bottle

This is an experiment using the reaction that happens when you mix vinegar and baking soda together.  We’ll put the two together and watch them inflate a balloon.

You will need:

• 1/2 cup of vinegar
• Baking Soda
• Plastic bottle
• Pour 1/2 cup of vinegar into the bottle
• Use the funnel to fill a small balloon about half way with baking soda
• Stretch the opening of the balloon over the mouth of the bottle.  Be careful not to let the baking soda fall into the bottle yet.
• When you’re ready, lift the top of the balloon until it’s directly over the bottle and let the baking powder fall into the bottle.
• Stand back and enjoy the science.

Once we dumped the baking soda into the vinegar, our balloon inflated so quickly that it popped off the bottle almost immediately. The boys thought that was great!

What’s Happening?

As the baking soda falls into the vinegar, it should begin to fizz and foam.  The baking soda is a base, and the vinegar is acidic.  When the two are mixed together they react and produce carbon dioxide gas.  The sudden expansion of the gas inflates the balloon.

If you want to learn more about the chemical reaction happening here, check out our post on the chemistry behind the vinegar and baking soda fizz.

DIY Plastic Bottle Rocket

Our kids are fascinated with space and planets, and the ideas of rockets blasting off.  They were excited to try their hand at building their own rocket and shooting it into the sky.  We’ll look at a few different designs and two different ways to fuel your plastic bottle rocket.  Make sure to blast of outside!

Chemical Reaction as Rocket Fuel

Baking soda and vinegar produces a classic acid/base reaction, and us a staple in science experiments for kids.  Here we’ll use the reaction as rocket fuel.

• Plastic Bottle
• Cork that fits the bottle
• 4 pens, pencils, or chop sticks
• Baking soda
• Tape or rubber bands
• Paint to decorate your rocket (optional)
• Use the tape to secure the pens or chopsticks to the side of the bottle with the opening.  You want them to be evenly spaced and be able to stand up when the bottle is upside down.
• Fill the bottle about 3/4 full with vinegar.
• Add about a teaspoon of baking soda to the bottle.
• Quickly insert the cork.
• Turn the bottle upside down and stand the bottle up on the pens or chopsticks (you want to be quick.)
• STAND BACK!

This is the same reaction we saw in the balloon inflation experiment above.  As the baking soda mixes with the vinegar, it should begin to fizz and foam.  The baking soda is a base, and the vinegar is acidic and produce carbon dioxide gas when mixed together.  The sudden expansion of the gas builds up pressure inside of the bottle. As the pressure builds, it pushes against the inside of the bottle.  The cork should be the weakest point, and when there is enough pressure to push the cork out, the bottle is propelled upward.

Air Pressure as Rocket Fuel

• Air Pump & needle adapter
• Use the tape to secure the pens or chop sticks to the side of the bottle with the opening.  You want them to be evenly spaced and be able to stand up when the bottle is upside down.
• Push the needle adapter into the cork.  Make sure the needle goes all the way through the cork so the aid can fill the bottle.
• Fill the bottle about 1/4 full of water
• Insert the cork snugly into the bottle
• Connect the pump to the needle adapter
• Turn the bottle upside down and stand the bottle up on the pens or chop sticks
• Move back and start pumping air into the bottle. 
• Wait for liftoff!  It may blast off suddenly, so be careful.

As the air is pumped into the bottle, pressure builds up and pushes against the inside of the bottle.  When the pressure builds up enough.  The cork should be the weakest point, and when there is enough pressure to push the cork out, the bottle is propelled upward.

If you don’t want to DIY it, or don’t have some of the items handy, you can get a complete kit with everything needed through this link on Amazon.

Wind Spinner from a Plastic Bottle

• String or fishing line
• X-acto knife or box cutter
• Paint or colored/reflective tape
• Decorate your bottle.  Use your imagination; Paint a colorful design.  Use shiny or reflective tape to make designs.
• Once you’re happy with the decoration, use the knife to make vertical cuts in the bottle , about an inch apart, all the way around.
• Push the top and bottom of the bottle together and crease the folds in the plastic about half way.
• Use the knife to cut a hole or “X” in the cap.
• Feed the string through the top of the hole and pull an in or two through.
• Tie a knot in the string at the bottom of the cap so it doesn’t pull back through the hole.  You may need to knot it several times
• Use the string to tie the bottle to a tree branch or hang it somewhere outside

When the wind catches the folds of plastic, it will spin the bottle around.

Tornado in a Bottle

• Liquid Dish Soap
• Fill the bottle 3/4 with water
• Squeeze in a few drops of dish soap
• Drop in a pinch or two of glitter
• Place the cap on the bottle
• Swirl the bottle quickly in a circular motion and put it down

You’re watching a vortex created by centripetal force . Huh?  The tornado in a bottle works like this: Spinning the bottle pushes the water against the sides and keeps in moving in a circular motion around the inside of the bottle.  Centripetal force acts on the water as it moves in a circular path and is directed toward the center around which the body of water is moving. The water winds up hugging the sides of the bottle as it spins. This creates a vortex in the center of the bottle, much like a tornado.  The glitter makes it easier to see the movement and effect.

You can get a similar effect by quickly stirring a glass of liquid and removing the spoon.  The liquid will continue to swirl around in a circular motion until it’s eventually slowed down by friction.

DIY Plastic Bottle Lava Lamp

In this STEM activity, we’ll learn about the properties of different liquids and how they react with each other. We’ll try to predict the affects and work on the powers of observation.

• Vegetable Oil
• Food Coloring
• Alka Seltzer (optional, but cool)
• Fill the bottle about 3/4 full with the vegetable oil.
• Fill the rest of the way slowly with water.  The water will sink to the bottom.
• Add about 10 drops of food coloring.

The oil is lighter than the water, so it will float on top.  When we add the water on top of the oil, it sinks to the bottom, as does the food coloring because it is water based.  Once the food coloring passes through the oil, it will mix with the water on the bottom.  Looks cool so far. At this point, we could just cap the bottle and shake it.  The oil and water won’t mix.  Shaking the bottle will infuse bubbles of colored water with the oil, and they’ll slowly separate as the water sinks and the oil floats on top.

Let automate it.  If you shook up your bottle already, wait until the water settles back to the bottom.  Drop a piece of Alka Seltzer into the bottle, and watch it sink to the bottom.  It’ll react with the water and fizz, mixing the oil and water with the reaction.

For a cooler effect, try shining a light under or behind the bottle.

Sensory Bottles

Our kids’ daycare was big on sensory bottles. They made all different kinds and had them in nearly every classroom. Sensory bottles are sometimes referred to as “calm down bottles,” so that makes perfect sense for a roomful of pre-schoolers. Since our kids enjoyed these while at daycare, we decided to make some at home.

The idea is to fill the bottle with things like water/food coloring, glitter, plastic glow in the dark stars, sequins, etc. The objects and colors swirling slowly around the bottle catch the eye and have a mesmerizing, calming effect on children, (and yes, lets face it – they work on adults too.)

The lava lamp project above could also be considered a sensory bottle.

You’ll need:

• Plastic water bottle
• Food coloring
• Glitter or sequins
• Clear School Glue (or vegetable oil like in the lava lamp )
• Fill the bottle about half way with water
• Add about 5-10 drops of food coloring, depending on how dark you want the color to be
• Dump in some of the glitter or sequins (or both)
• Fill the remainder of the bottle with the glue or oil
• Cap the bottle and shake

Experiment with different amounts of water vs glue or oil. The more viscous the mixture, the longer things like glitter will suspend. Make it too thick, and it won’t move much. It’s more art than science on this level. Try experimenting with different themes. One of our boys brought home an “Ocean in a Bottle” with sand and shells inside. You could use plastic beads, small alphabet tiles, or whatever strikes your interest. Let your imagination take the lead.

Plastic Bottle Shaker

With all of the toys we had in the whole of the house, it was a small water bottle filled about 1/4 with dry rice that captivated our infant son for several months. It was his go to toy. All you need is a plastic bottle and something to fill it with. Rice, dry beans, or anything of similar size to shake around. Experiment with different sized bottles and different fillings to see what kind of tones you can get. As a musician, I’ve found these to be quick, cheap, and simple substitutes for shakers or maracas.

Self Watering Planter Made from a Plastic Bottle

This activity can work with different sized bottles, depending on what kind of plant you’d like to put in it.  We did it with both a 2 liter soda bottle and a 12 oz water bottle.  The cool thing about this setup is that it is self watering.

• A plastic bottle
• Cotton string or a piece of cloth
• Potting soil
• Seeds or a plant
• Cut the top off the bottle between 1/2 to 2/3 from the bottom. You don’t need to measure exactly. Cut carefully, the plastic can have a sharp edge. 
• Once you have cut the top off, fill the bottom portion of the bottle with water
• Turn the top part upside down, and fill with potting soil
• Place your plant (or seeds) in the dirt
• Make a small hole in the cap, or make an “X” shaped incision
• Feed the string or cloth through the hole
• Place the cap on the bottle.  The string or cloth will hang down into the water and act like a wick.
• Place the upside down portion of the bottle with the plant into the bottom portion of the bottle you filled with water

Ecoshpere in a Plastic Bottle

We can take the planter idea to the next level with a few small hacks and build an ecosphere.  We’ll be using two bottles of a similar size and shape. For this STEM project, we’ll cut the bottles and reconfigure them to make what looks like a bottle with two tops on opposite ends. We’ll place this in the bottom portion of one of the bottles just like the regular planter above. Sounds crazy, but follow along and we’ll make something cool together. You’ll need:

• 2 clear plastic bottles
• A small plant
• Several pill bugs or earthworms (optional)
• Cut the top off both bottles between 1/2 to 2/3 from the bottom.  You don’t need to measure exactly.  Cut carefully, the plastic can have a sharp edge. 
• Make a small hole in one of the bottle caps, or make an “X” shaped incision
• Feed the string or cloth through the hole.
• Place the cap on one of the bottle tops.
• Turn the top part of capped bottle upside down, and fill with potting soil
• Place your plant in the soil
• Position the top of the second bottle onto the first so the edges that were cut are aligned
• Tape the bottles together. (A bit of planning ahead and you can line them up so the tape line is about even with the soil level for a better aesthetic. Bonus points for using Duct Tape with patterns .)
• Fill the bottom portion of one bottle with water.
• Place the upside down portion of the bottle with the plant into the bottom portion of the bottle you filled with water. The string or cloth you pulled through the hold in the cap will hang down into the water and act like a wick.
• If you’ve decided to add in a few insects or worms, go ahead and drop them in the top.

Air Pressure and the Empty Plastic Bottle

Here’s a simple activity to demonstrate the effects of air pressure. You’ll need 2 things you probably have around the house:

• A Plastic Bottle
• A piece of paper
• Crumple the piece of paper so it just large enough to fit into the mouth of the bottle
• Place the bottle on its side
• Place the piece of paper in the mouth of the bottle

Pause for a moment and make a hypothesis. If you blow the balled up paper, what would you expect to happen?  It should just blow into the bottle, right?

Try it.  Go ahead, we’ll give you a moment.

What happened?  Were you surprised?

The paper came OUT of the bottle, didn’t it.  How did that happen if you blew into the bottle?  This is Bernoulli’s Principle in action.  Bernoulli’s Principle predicts that an increase in speed will cause a decrease in pressure.  What does that mean for our exercise?  When you blow onto the paper, you cause the air to move faster on the outside of the bottle, which creates lower pressure.  Since the air pressure inside the bottle is now higher, the air pushes against the crumpled ball of paper and pops it out of the bottle. The pressure inside and outside the bottle is now equalized and all is right in the world.

This is the same principal behind the design of airplane wings , that gives the airplane lift and helps keep it in the air.

Ocean in a Bottle with 3 Simple Ingredients

Last updated on June 11, 2020

• Facebook 6.5K
• Pinterest 198.1K

Make an ocean in a bottle with 3 easy ingredients.  One of the fastest and easiest-ever science activities for preschoolers .

I love to make  homemade toys for the hooligans.  Discovery bottles are always a favourite here.  They look so beautiful, and no matter what we fill them with.

This particular ocean in a bottle has to be the most amazing looking bottle we’ve made yet though!  It was SO easy to make, and you likely already have everything you need on hand.

This oil and water science experiment isn’t new by any stretch of the imagination.  It’s a classic preschool science activity that’s been around for years.  I actually can’t believe we haven’t done it before!  Yesterday, I happened upon this learning discovery bottle over at Play Trains, and I decided we’d make an ocean bottle of our own today.

To make our Ocean in a Bottle, we used:

• cooking oil (we used canola, but vegetable would work well)
• blue food colouring
• large clear, plastic bottle (2 litre pop bottle, shampoo bottle, mouthwash bottle etc.)

TIP:  a mouthwash bottle is perfect, as it has a child-proof lid which prevents the kids from opening it when playing with it.

If you want to explain the scientific details to your child, pop over and check out this article explaining why oil and water don’t mix .

How to make an ocean in a bottle:

I didn’t have a 2L pop bottle on hand, so we used an empty mouthwash bottle.   I like that the lid is child-safe, and too challenging for little hands to twist open.  If you’re using a bottle that’s not child-safe, you might want to run a little hot-glue around the inside of the bottle lid.

• Fill approximately 1/3 of your bottle with water.
• Add several drops of food colouring.
• Have your child shake the bottle to disperse the food colouring.

Now, simply top up the bottle with oil.  I filled ours right to the top and then popped the lid on.

Let the fun begin!

Tip the bottle upside down and watch your ocean come to life.

The pictures really don’t do this activity justice. You have to see it in action.

The way the waves roll cascade inside the bottle is just beautiful, and watching the big blobs of colour swoosh and fall through the yellow oil is really fascinating.

The more you agitate the bottle, the more the bubbly the ocean becomes.

Set your bottle down occasionally to let the bubbles settle, and then start all over again.

Doesn’t it look amazing?

Do you use 1/3 oil .then fill up with water

1/3 water, and then fill up with oil, Dorothy.

June 22, 2016 at 11:06 am

If you fill 2 litre bottle with oil, very expensive project?.???

June 23, 2016 at 12:10 am

You could use a smaller bottle, and probably get away with a half cup of cooking oil. If you think about it this way: you would use a cup of oil to bake a cake, and the cake would be gone in a couple of days. This will last forever. 🙂

May 31, 2014 at 5:34 pm

This is just WAY cool! I LOVE it and as an adult, I’d want to try it. I can’t wait for my son to get a little older and do cool stuff like this with him. Thanks so much for sharing!

Would baby oil work?

Jackie Currie

June 8, 2023 at 4:36 pm

I haven’t tried making them with baby oil, Helen, but I imagine it would work!

Selina Strong

June 1, 2014 at 9:43 am

Please revise the instructions for ocean in a bottle. Oil is one of the three ingredients, but there is no mention of adding the oil to the bottle. Surely it is either added first ( although the food coloring doesn’t mix in ) or second? Thanks.

June 10, 2014 at 10:44 am

After the food coloring and water are shaken, the instructions say “Now, simply top up the bottle with oil.”

June 10, 2014 at 1:09 pm

Yes, simply top up the bottle with oil. That’s right, Dan.

June 9, 2014 at 6:04 pm

Such fun!! Using mineral oil instead of cooking oil means the oil is clear and I really love that effect with the food coloring in the water and the other half (the mineral oil) perfectly clear.

June 9, 2014 at 7:28 pm

Yes, or baby oil would have the same look too. I must pick some up at the dollar store!

Michelle Bordeaux

June 9, 2014 at 10:13 pm

This is really cool. I was thinking about doing it as the craft for an Easter Egg Hunt next year (2015). I was also thinking about buying small plastic sea creatures and/or small shells to add a few in. Have you tried anything like that before?

June 9, 2014 at 10:50 pm

I haven’t in the oil and water bottle, Michelle, but I’ve added odds and ends to bottles that I’ve filled with water or hair gel or coloured rice! I think it’s a great idea!

June 9, 2014 at 11:20 pm

Thank you for the response, I will have to test out a few ideas .

June 20, 2014 at 8:57 am

In case you are tempted to add glitter for a touch of glam… Don’t do it! Maybe someone who knows science better than I do can explain it, but it looks like the glitter catches everything up and emulsifies it , so it takes a very long time for the oil in the water to separate again! I just threw everything away and started over!!

September 22, 2014 at 9:38 pm

Thanks so much for the warning! That would have been something we’d try.

July 3, 2014 at 4:07 pm

Shake it too much and it never separates again. Very disappointed in this project.

July 3, 2014 at 8:11 pm

Very interesting, Nancy. Never?

August 7, 2014 at 9:12 pm

I think thats what happen to mine! right off! boo boo! Wish I had read this before I shook it like a crazy person! 🙁 now I have to go to the store and buy more oil

April 16, 2015 at 3:16 pm

That’s actually, totally, not possible. Chances are there was something else in your bottle to begin with. If it was an old lotion or soap bottle there could have been some residue left in the bottle from what was in it before that emulsified it. Water and oil cannot permanently emulsify from vigorous shaking alone. It needs the addition of an emulsifier.

April 16, 2015 at 3:35 pm

Oh, that is a very helpful response, Megan. Thank you! I was wondering how the oil and water could become completely emulsified, as mine always separate after resting. Brilliant. Thank you!

July 3, 2014 at 7:26 pm

We just made these for a preschool program. We called them sink-or-float bottles. We added small seashells and the larger glitter shapes. It was a great demonstration of what the word displacement means. The kids and parents loved them. 🙂

July 6, 2014 at 2:21 am

My 2y.o. will enjoy it 🙂 Thank you!

July 21, 2014 at 8:44 am

Absolutely beautiful. I think of the yellow oil as sunshine filtering through the water.

August 8, 2014 at 3:17 pm

Can you make this in a smaller bottle? I’d love to do this as a take home craft for my son’s birthday party, but I don’t know that I want to go in search of 14 2 liter bottles. Thanks!

August 9, 2014 at 10:14 pm

You could give one a try and see how it turns out, April.

July 1, 2015 at 3:21 pm

My younger brother (age 12) and I just did this experiment with an empty Poland Spring bottle. Still worked great!

July 2, 2015 at 11:26 am

Yay! So glad you loved it!

July 9, 2015 at 5:27 pm

they have those small water bottles, that would be great for a kids party thing. Perfect size too. I’m going to try this with sand and sea shells and make a beach in the bottle with my daughter. Hopefully it works…

August 16, 2014 at 6:32 pm

Ok, I am 57 years old and I love this. My son is 32 and have no grandbabies yet so this is for ME. I am decorating my home in the beachy coastal style and this would be a great way to bring the ocean into my home since there is no ocean near where I live in “Missouri”. I will put it in a large pretty bottle and sit it near my sea shells and let people shake it up and admire it when they come to visit. Thanks!

October 25, 2014 at 12:35 pm

I’m an 8th grade science teacher … and believe me … many of your experiments will enchant and delight 8th graders too. Thank you for these that show kids that science is interesting and FUN!

November 20, 2014 at 6:59 am

Tnks i won the science fair tnx for sharing

December 17, 2014 at 10:32 am

I used this for a white elephant recycling themed gift exchange for my cub scout. My son loved doing this, we used a baby oil bottle, bonus we used the last third of the oil for the project and topped it off with some veg oil. He chose blue also. And since it’s for scouts, we used plastic putty glue to permanently (I hope)glue shut the lid. Should be fun! Thanks!

December 17, 2014 at 7:07 pm

Trying to think of a way to use this as decor for an Ocean themed wedding. My niece is getting married next year and I think something like this would be awesome to display, maybe on tables. Just not quite sure on bottle types and if putting in sea shells would work. Any suggestions??? Pls help!

December 18, 2014 at 9:33 am

I’ve similar bottles with shells added, Heidi. As for how to display them, there’s a brand of bottled water called Voss. I’m not sure where you are, but if you have it there (in your grocery stores), you could use those bottles. It’s pricier than regular bottled water though, so you may need some pals splurge on it once in a while, and give you the bottle when they’re done. You could also check Michael’s or Hobby Lobby for interesting looking containers with lids that seal tight.

February 21, 2015 at 11:48 pm

The easiest place for me to find VOSS water locally is at Walgreen’s drugstores. They are often on sale, too, for $3 for two bottles.

Chickielady

August 25, 2015 at 9:31 pm

We used a VOSS water bottle for a similar project at our school and it was dropped on the floor and the lid cracked open. I’ve used soda bottles and not had this problem. I have saved some bottles from dry roasted peanuts to use.

February 1, 2015 at 8:22 pm

i tried it, its so cool! but instead i used a small coke bottle and eyeballed it!

March 14, 2015 at 1:39 pm

I was so excited to do this but I tried it twice and it didn’t work. I ended up with a layer of blue water and a layer of oil on the top no matter how much I shook it. Was it because I used vegetable oil?

March 14, 2015 at 1:40 pm

I mean olive oil?

March 14, 2015 at 10:51 pm

That might be the reason, Mae. I can’t think of any other reason it wouldn’t have worked for you.

April 8, 2015 at 5:37 pm

Hi! I came across this craft on Pinterest, and decided to try it with my tween sister (I’m a teen).

We made this craft and absolutely love it! We used smaller bottles, so we could display them on our window sills. I love to look at it, and I’m definitely going to make it again, and use green, pink orange, purple, any color really.

I wrote a review about it on my website if you want to check it out!

April 8, 2015 at 7:12 pm

Hey Ally! So glad you loved the ocean in a bottle. I think it’s great that you and your sister made them. An assortment of colours would be awesome! I need to do that too. Cool blog you’ve got there, girl!

May 16, 2015 at 9:37 am

I live 100 meters from the shore, I think I could just walk there with te bottle and trap some fishstinking water and called it “sea in the bottle” how about that 😀 😀

May 31, 2015 at 12:40 am

yeah….didnt work…4 year old was so disappointed…

May 31, 2015 at 12:49 pm

How odd. It’s simple science. I can’t imagine what would go wrong unless perhaps there was residue in your bottle. That could prevent the oil and water from behaving properly.

June 12, 2015 at 6:46 pm

This is great, thank you! My toddler and I used mini water bottles and they were the perfect size for little hands doing the pouring, squeezing, and shaking.

Allison Jones

June 19, 2015 at 6:56 pm

Beautiful! Great activity for the kiddos

July 22, 2015 at 3:59 pm

I made this when I was in Kindergarten. The teachers used baby food jars and just super glued the lids shut. We got to pick out tiny sea animals to put in ours. Definitely one of my favorite projects since I still remember it 20 years later!

August 1, 2015 at 5:26 am

awesome idea! add 1/2 alka seltzer tablet or other tablets that fizz and use half the quantities of oil and water. Stand back and watch it fizz! for more help on how to make this go here…. http://www.sciencekids.co.nz/experiments/easylavalamp.html

August 26, 2015 at 3:19 pm

I absolutely love this idea! We save our cleat 2 liter bottles for science and crafts, so we’ll have the bottles when we want to do something like this. Not too crazy about using 2/3 of 2 liters of oil though, so we’re going to definitely use a smaller bottle. Glad to know about glitter not being a good idea for this. If someone want’s a great science activity using 2 liter bottles, one is the tornado in a bottle and the good news is, glitter is a really good idea to put in them! On the other side of a coin, I’m already planning our Cub Scout Blue and Gold Banquet for next year. Planning on a theme to do with the sea, maybe Cubs Under the Sea or something like that. This will be perfect to have on the tables for both decoration and take home! Thanks for the wonderful idea!

December 12, 2015 at 8:19 pm

This is beautiful. I love the blue – very soothing. My nephews will love this, but i was also thinking what a great stress reliever it would be on the desk too.

December 12, 2015 at 10:13 pm

I love it just as much as the kids do, Cheri. It’s very relaxing!

January 20, 2016 at 1:14 am

I was wondering if it would work if we put it in ziplock bags and double sealed it with tape and put it in another zip lock bag?

January 21, 2016 at 7:52 pm

It might, Jayne. It’s up to you weather or not you want to risk the bag popping. That’s a lot of oil in there, which would ruin carpets/furniture etc if it did leak.

May 2, 2016 at 1:16 am

Is it working only with food coloring? Is it okay to use water color or acrylic paint?

May 3, 2016 at 12:05 am

Watercolour paint would work because it’s water soluble. I don’t think acrylics would work as well, but I’m just guessing there.

June 5, 2016 at 11:47 am

Just did this with my kids and didn’t turn out at all like I expected. The oil began to solidify after about 5 minutes of play, so it’s cloudy

June 6, 2016 at 9:44 am

How strange. What kind of oil did you use, Asia? Was it fairly fresh? I know old oil can go cloudy when you shake it up. As for solidifying, that is really odd. I’ve never known an oil to solidify.

November 13, 2016 at 11:28 pm

I made this myself and the oil became cloudy after first use, it was pretty fresh. And instead of going through the water, it went down the walls of the jar, so no ocean effect. I also washed it before putting stuff in it. I’m wondering what happened?

November 15, 2016 at 12:15 am

Hmm. I haven’t a clue, Kayaqua. I haven’t heard of that happening before. I’m sorry I can’t offer you a solution!

January 28, 2017 at 8:40 pm

could the food colouring work with paint?

Pam backman

April 17, 2017 at 1:36 pm

I do this every year with my preschool class. I use a small gatorade bottle or dr pepper instead of water bottle as the are thicker plastic. I have also used baby oil because it is clear. We habe out toy fish and sand in to make it more authentic looking. Sand was not as pretty . I let the kids choose the color so each one is unique and theirs.

April 17, 2017 at 1:42 pm

Should be have used toy plastic fish

April 23, 2017 at 10:33 am

This is really cool! I really want to make this. I need something to shake sometimes, if ya know what I mean. I made something too! I just used a baby food jar,filled it with water,add a drop of dish soap. Last add some pieces of string. Swirl it around. Really fun! In my opinion.

May 29, 2017 at 8:31 am

Would it still work well if I mixed this with a “jellyfish in a bottle”? I’m interested in making one if so. I might try it out soon!

May 29, 2017 at 2:06 pm

It might, but I’m not sure if the oil would interfere with the behaviour of the jellyfish. I’d give it a shot if I were you. Worst case, you can remove the jelly fish and still have an awesome sensory bottle for the kids to play with and observe.

July 18, 2017 at 11:45 am

My Church will be do this with VBS kids next summer. Thank you for sharing!

July 19, 2017 at 4:26 pm

Yay! You’re so welcome, Cyndi!

September 4, 2017 at 12:46 am

It works with water down acrylic paint

September 18, 2017 at 4:55 pm

To those getting cloudy oil, i suspect you are leaving air inside the bottle. If you shake it really hard with air inside, it will mix tons of air bubbles into the oil and make it cloudy. Try to let as little air inside the bottle as possible.

December 10, 2017 at 12:23 am

Will water colour not work instead of food colour?

February 16, 2018 at 1:03 am

I actually just made one of these for me to relax me…after my parents stopped freaking out because it’s something different and weird. I love the effect of the water and oil, and the food colouring ties it all together with the yellow-green-blue. A brilliant idea, and a beautiful one, at that!

February 21, 2018 at 12:46 am

Wonderful! I’m so glad you love it. How nice to know that it’s not just preschoolers enjoying our activities!

March 29, 2018 at 1:13 pm

This project turns out so well! I tried it with my toddler and he was completely amazed by the ocean in a bottle. I shared your link on my blog as part of a post about activities to do with toddlers indoors. Thank you for sharing such a great idea!

Leah Winters

April 20, 2018 at 10:57 pm

Hi Jackie! I love your project and linked it to my blog – would love to connect with you about cross-promotion if you’re interested.

February 19, 2019 at 9:02 pm

hey, just wondering im doing a project for my class is there anything else I need to worry about before I start. also what color is best?

February 19, 2019 at 9:12 pm

Hi Sam. Nothing really to worry about. Just make sure the lid is on tight of course. We’ve only used blue because we wanted it to look like an ocean, but I imagine any colour would work. Red or purple would be pretty cool. It might look like a lava lamp!

June 5, 2019 at 11:16 pm

So, just to get this straight in my head, it’s 2/3 water, blue food color, mix, add 1/3 oil??? Do you leave any air space? Thank you!

June 6, 2019 at 2:45 am

“Fill approximately 1/3 of your bottle with water. Add several drops of food colouring. Now, simply top up the bottle with oil. I filled ours right to the top and then popped the lid on.”

April 15, 2020 at 7:39 pm

Is it normal for it to look cloudy after a day? I used canola. I wonder if that’s normal for that type oil?

April 16, 2020 at 8:57 am

Hmm… Is it possible your bottle wasn’t completely clean? I’m thinking if there was any bacteria in it, it could cause the contents to go cloudy and eventually develop mold.

Shreiya Aggarwal-Gupta

June 25, 2020 at 3:36 am

Thanks so much, Jackie! This is so, so simple and enjoyable even though it’s been so many years since you published, obviously. I also enjoyed reading the tweaks in the comments. As you said, the pictures don’t do the activity justice – it’s simply amazing to see it in action 🙂

November 13, 2020 at 1:10 am

Help! I followed your instructions to a “T”, and it was beautiful . . . for a week. I even bought fresh oil, to ensure that everything would work perfectly. But after a week, something began to happen, where it looked like some of the oil was somehow disintegrating into the water — the water ended up looking dull, murky, and translucent instead of transparent, giving the effect of dirty, polluted water. I’m really disappointed, as this project looked just so stunning at first that I almost wanted to keep it for myself instead of giving it to my grandson.

Please advise! Thanks!

November 14, 2020 at 8:20 am

Hi Diana, I wonder if there was some residue in the bottle that caused bacteria to form, or somehow, while making it, bacteria entered the bottle. We made our bottle about 6 years ago, and only recently did ours start going cloudy.

November 16, 2020 at 11:46 pm

Thanks for your reply, Jackie. I actually washed out the bottle (a new Voss glass water bottle) very thoroughly with hot soapy water and then carefully rinsed it out with hot water several times. And as mentioned in my previous email, I purchased a new bottle of oil for the project. The finished project was initially so beautiful when I first made it that I hate to give up. I think I’ll try it again with distilled water to see if it makes a difference. If it does, I’ll let you know.

November 18, 2020 at 12:12 pm

SO strange, Diane. I hope it works for you with the distilled water. Please let me know how it goes!

Fun Science Experiments With Bottles

Article By : Jonathan @ BottleStore

Did you know you can learn about science with a couple of bottles and a few things out of the cupboards in your house? There are lots of great experiments you can try with the bottles that are probably in your family's recycling bin right now. Any kind of plastic bottle will do: old soda bottles, water bottles, or any other kind of bottle you might find in there. Gather up a few and get ready to try some experiments that will amaze your friends and family.

Working on science experiments with your friends, your parents, or maybe even your brothers or sisters can teach you lots of things, and not just about science. When you work with someone else to do an experiment, you're going to have to use a lot of other important skills. First, you're going to need to cooperate with the other people doing the experiment, meaning that you have to work together well. Everyone needs to take turns doing a step or adding an ingredient. You'll also have to communicate, or talk, with each other to make sure you gather all of the right stuff to do the experiment. You might even need to do some math because sometimes, you'll have to measure ingredients like water or baking soda. Last but not least, you also have to be patient. Sometimes, experiments are hard or they don't work out the first time, so you have to be patient with yourself and the other people working on the experiment and just try again! When an experiment works out, it's so cool that it's worth the work.

There are lots of reasons to do science experiments. You might do them at home on a rainy day when you can't go outside and you just want something fun to do. You could do them to put on a show for your parents or your friends. Some science experiments are just like magic! For example, in one experiment, you can make a hard-boiled egg fit through the tiny opening on the top of a soda bottle. It sounds impossible, but it's true. There's even an experiment that lets you stack liquids like blocks inside of a bottle. Your friends will think you did some crazy magic, but you really just used your science skills to do an experiment about the densities of different liquids.

Another reason to do science experiments is for a school science fair. You could teach your classmates and the people who come to the fair about weather by making clouds or tornadoes in bottles. Guests at your exhibit will get a chance to try a hands-on experiment that they'll remember when they walk away, and you'll get to have fun teaching them something new.

Getting involved in science now could help you in the future. Every day, someone in the world takes a step toward making a new scientific discovery. There are still so many things we don't know about the world around us, the universe, and how things work. A career in science can be an exciting way to spend your whole life doing experiments and finding out things that could help people, like finding the cure for a disease or a way to travel farther into space. Science has so many uses that the possibilities are endless. There are scientists who work in zoos, on big farms, in hospital laboratories, and so many other places!

Before you go jumping into doing some experiments, though, make sure that you stay safe. It's a good idea to always wear goggles to protect your eyes from liquids that splatter or things that break. You should also wear gloves to protect your hands from any liquids that might harm your skin. If you're trying a new experiment that might be a little risky, you should make sure an adult is nearby to help just in case something goes wrong. Last (and this one is really important) always ask your parents before you do an experiment. Make sure you have permission to use the bottles or other stuff you find around the house. Plus, some science experiments can be pretty messy, so it's a good idea to let your parents know what you're doing so they can tell you the best place to try your experiment. Science is fun, but getting in trouble isn't!

Water Cycle in a Bottle Science Experiment

I'd love it if you shared!

• Facebook 20
• Pinterest 2.6K

Spring is the perfect season to celebrate all things water, rain, and clouds. This spring, make this easy water cycle in a bottle science experiment with your class to illustrate how the water cycle works up close and personal. Kids will love making their own water biomes in a bottle and will be fascinated to watch the water turn into a gas, turn back into a liquid, and fall back into the bottom of the bottle.

Make this fun spring science activity with your class!

Supplies for the Water Cycle in a Bottle

• Plastic bottle
• Plastic cup
• Ice cubes (optional)
• Blue food coloring
• Permanent marker

Setting Up for the Water Cycle in a Bottle

Remove the labels from the bottles. Add a drop of blue food coloring to each bottle and fill about 1/3 of the way with water. Screw the caps on tightly.

Doing the Water Cycle in a Bottle Experiment

Let the kids decorate their bottles with clouds, water and rain drops.

Turn the bottles upside down inside a cup.

Discuss the water cycle and why water evaporates and rains.

Place a couple of ice cubes on top of each bottle and set it in a sunny location.

Check the bottles after about an hour.

There should be condensation on the top of the bottle, and there may even be a small cloud there!

Watch as the droplets of water fall back to the bottom of the bottle.

Water Cycle in a Bottle Questions to Ask

Will the water cycle occur even without the ice cube?

What happens when you put the bottle in the sun?

How long does your mini water cycle take to complete?

The Science Behind The Water Cycle in a Bottle Science Experiment

Water has three states of matter: Liquid, gas, and solid. When liquid turns into a gas, this is called vaporization. Water evaporates, turns into a gas, and rises into the air. This collects water droplets at the top of the bottle, known as condensation, when gas turns back into water. When the water gets heavy enough, it falls back to the bottom of the bottle just how rain falls back to earth. Water evaporating and then turning back into a solid or liquid and returning to earth is the water cycle.

What are discovery bottles?

Scientific bottles or discovery bottles allow kids of multiple ages to enjoy exploring easy science concepts together! Plus plastic science bottles are great to leave out in a basket at a science center at home or school. Sit down on the floor with young kids and allow them to roll them gently around.

TIP: You can tape or glue caps if needed!

Yes, I have used glass jars and I made sure to supervise my son closely. Please use plastic if that is best for you! We have started using the VOSS plastic water bottles for our discovery bottles and really enjoy them!

Ten science experiments you can do with a plastic bottle – Part 1

Do you love science and want to try out some experiments yourself? Do you worry that you’ll need special equipment and expensive kits? FEAR NOT! There are so many science experiments you can do with things you have around your home RIGHT NOW! Just remember to always ask an adult’s permission. Finish drinking your water and save that bottle because we are going to share TEN amazing experiments with you… you’ll never look at a plastic bottle in the same way again!

A few months ago I promised to share ten experiments you can do with a simple plastic bottle. If you have been following me on Face Book you will have noticed that I have shared one every week and we reached ten no problem; I’ve compiled all the instruction videos here so that you can pick and choose which ones you want to do (or, even better, try all ten). The reason I started this was because I was sick of seeing science experiment kits full of rubbish (I am not saying all science kits are rubbish, but I have seen my fair share lately). I wanted to show you that you can do plenty of science experiments from things you have around your own home. And what better example to use than a simple, humble, plastic bottle. A great example of reusing and recycling.

PLEASE NOTE: ALL THESE EXPERIMENTS REQUIRE ADULT SUPERVISION!

Without further ado… here are first five Science Experiments you can do with a plastic bottle:

make a fire extinguisher

2. Inflate a balloon

3. the sneezing alien experiment.

4. and 5. Ocean in a bottle experiment and Lava Lamp experiment

Those are the first five experiments. Have lots of fun with them, check back next week for the next five experiments . Remember to keep those bottles!

As always, we love to get comments and feedback so do let us know if you try some of these experiments; we’d love to know how you get on, did you make some of your own modifications and improvements to the experiments? Would you like us to share more video experiments?

We have tried four of these five and have had a ball in doing so. My five year old was so eager to do them and really enjoyed it all. Our almost 9 year old neighbour was well impressed with the experiements when we repeated them for him. In fact we spent several afternoons showing off our newfound proficiency in science to anyone who was interested 😉 Thanks so much for sharing these, Naomi. Fionnuala & the boys

This is lovely to hear Fionnuala! I’m delighted with your feedback – thanks! I hope they get to enjoy lots more science experiments!

I will be checking all of these out, thank you for sharing. I know my children will be delighted to be doing real experiments.

Great Joanna, I’m sure your little scientists will love them!
