Blowing up a Balloon With Dry Ice
This Demonstration is included in a bundle of 101 Science Demonstrations & Experiments. You can find this bundle here in my TpT Store. These exciting demonstrations use mostly inexpensive materials that you can find around your home or can be easily purchased. I show how to run the demonstration, give helpful advice and explain the science concepts behind it. Many of these demonstrations can be turned into STEM projects for your students.

Materials needed:
Dry Ice
Towel
Safety Goggles
Insulated Work Gloves (for handling dry ice, see the safety section at the end of this video)
Balloons / Disposable (latex) Gloves
Water
Super-Cool Lab Coat, optional 🙂
Directions:
***Please watch my dry-ice safety section at the end of this video before trying this demonstration.***
Keep the dry ice inside your towel to help slow down the sublimation process.
- Add a small amount of water into your balloon or glove.
2. Add a small piece of dry ice into your balloon or glove. It is easier with a glove, but you can also use a balloon if you have someone else hold it open for you.
3. Pinch and tie the opening as quickly as possible. Give it a shake to make sure all of the dry ice is in contact with the water and not stuck inside of any of the glove fingers.
Eventually it could pop…place it somewhere safe!
The Science Behind this Experiment:
Dry ice sublimates. It goes from a solid directly to a gas without stopping at the liquid phase. Adding water makes the sublimation happen even faster!
