If you’re looking for super fun and easy science experiments for kids, then look no further! Dry ice experiments are a cool way (literally!) to learn about science and have a great time with the kids.

Of course, you’ll need to supervise the kids and follow some simple safety rules during these fun dry ice science activities, but we can assure you, nothing beats these amazing, cool experiments!

Frequently asked questions

But before we get down to experimenting with dry ice, let’s first dive into the simple science behind dry ice.

What is dry ice?

Dry ice is a solid, frozen form of carbon dioxide. It is extremely cold and passes from a solid state directly to a gaseous state (that is, it sublimates) without turning into a liquid. That is why it got such an apt name – “dry ice”.

Safety rules

We strongly recommend that the following safety precautions be followed during all dry ice training and experiments. Dry ice is relatively safe, but should be handled with care. To ensure safety, follow the rules below:

Use tongs or gloves to handle dry ice. Do not touch it with your bare hands as this may cause frostbite.
Use an ice cube tray to store dry ice. Do not store dry ice in the freezer compartment of the refrigerator.
Choose a well-ventilated room for dry ice experiments to allow air to circulate and remove excess carbon dioxide produced during dry ice operations.
Cover a table or counter with towels to place dry ice on. Never place dry ice directly on a table or countertop, as this can damage it.
Adult supervision is strongly recommended.

To be safe, just follow the instructions above when doing all of the dry ice demonstrations below.

Interesting experiments with dry ice

Now that you know what dry ice is and where its name comes from, without further ado, let’s get into some fun and exciting dry ice experiments that you can do at home or in the classroom.

These dry ice demonstrations are perfect for large groups, birthday parties, and fun science projects.

Note: Please follow safety precautions when performing all of the following activities and experiments with dry ice.

1. Prepare a potion

This is the easiest dry ice experiment for kids. He delights everyone – from preschoolers, elementary school children and older children to even adults!

Dry ice
Hot water
Flask
Tongs

1. Fill the flask halfway with hot water.

2. Using tongs, drop a piece of dry ice into the water.

That’s it! When you drop dry ice into hot water, the water begins to bubble and a thick mist comes out of the neck of the flask.

This is because when dry ice sublimates in water, carbon dioxide is released in the water, which makes it fizz! Again, the reason for the fog is simple science.

As the cold gaseous form of carbon dioxide leaves the flask, it comes into contact with the water vapor contained in the air. This water vapor then condenses to form fog!

This same trick is often used in movies and at Halloween parties to create fog! This is a fun experiment with dry ice that you can do at home and a fun Halloween activity for kids.

2. Screaming spoon

If you’ve used metal tongs to remove dry ice, you’ve probably wondered what that strange sound is! That’s the point of this dry ice experiment.

To make a screaming spoon, simply place a piece of dry ice on the spoon and hear it scream (or squeal!).

This eerie metallic sound is created by the sublimation of dry ice. Turning into a gas, it causes the metal to vibrate very quickly. Thus, this screech is created.

3. Bubbles from dry ice

Nothing can be more exciting than creating bubbles! However, smoke bubbles sound even more fun.

Bowl
Hot water
Dry ice
Detergent
Tongs

1. Pour water into a bowl, almost half full.

2. Add a few drops of dishwashing detergent to the water and stir to dissolve.

3. Using tongs, lower a piece of dry ice into soapy water.

When dry ice sublimates, CO2 gas enters the soapy water. Bubbles filled with dry ice mist are formed. Rip them open and watch the mist erupt from the smoke bubbles.

Just wonderful and charming!

4. A crystal ball made of dry ice

This is one of the coolest dry ice experiments you’ll ever see! It looks like it’s straight out of the Harry Potter movies and looks great.

Perfect for a cool Harry Potter themed party or dry ice science projects. Crystal ball is simple and fun!

Bowl – 2
Hot water
Dry ice
Detergent
Tongs
A cotton handkerchief or a long strip of soft fabric

1. In a bowl, prepare a soapy solution by mixing room temperature water with a few drops of dishwashing detergent. Let him defend himself.

2. Pour water into another bowl, almost half full. This is the bowl on which we will make the crystal ball

3. Dip your finger in soapy water and run it around the edge of the crystal ball bowl.

4. Take a soft handkerchief and immerse it in soapy water. Take it out and carefully squeeze out the excess soapy water.

5. Now place the handkerchief over the opening of the ball and carefully run it along the edge of the bowl. As you do this, you will notice a film of bubbles forming around the edge of the bowl.

This is the trickiest part of this fun dry ice experiment, and it may take a few tries before you manage to remove the tissue from the bowl without breaking the bubble.

Quick tip: Be careful but sure and move the handkerchief smoothly.

Once the bubble wrap sets, wait and watch! The trapped carbon dioxide inflates the bubble to form a spectacular (almost magical!) crystal ball! Let the bubble grow in peace until it finally bursts!

Quick tip: Add some funny science jokes to make the experiment even more fun!

5. Exploding jar

Looking for a crazy idea of what to do with dry ice? Here’s one, but it’s an outdoor science experiment and shouldn’t be done indoors.

All you have to do is put some dry ice with a little water in an airtight jar, put a lid on it, put it outside and away you go. After a while, the jar will explode and its lid will fly away!

Quick Tip: Add science puzzles with answers to get kids thinking!

6. Blow up the balloon

This is a fun dry ice experiment for kids, especially the little ones. Just take a bottle with a narrow neck, put dry ice and water in it. Cover the neck of the bottle with a balloon.

When the dry ice sublimates, it inflates the balloon. Simple and fun!

Quick tip: You can replace the balloon with a plastic glove to add some fun to the experiment!

7. Create a comet model

This is a great dry ice experiment for high school students and space enthusiasts. It takes almost 20 minutes to complete and is a great idea for a science project.

8. Make instant ice cream

What could be a better experiment with dry ice than making instant ice cream? Follow our easy recipe for making bagged ice cream at home and replace the regular ice and salt mix with dry ice for instant homemade ice cream.
