What can kids do with dry ice?

The CO2 sublimates and the vapor fills the balloon or glove – possibly to the point where it pops!

  • Frozen Bubbles. Freeze a soap bubble over a piece of dry ice.

What happens when you put dry ice in soapy water?

In this dry ice experiment, the ice is dropped into soapy water. When the dry ice sublimates, the carbon dioxide and water become trapped inside the soap film bubbles. When you pop the bubbles, you release the “fog”.

How do you make fog with dry ice and water?

Fill a metal or plastic container half full of hot water and add a few pieces of dry ice every 5-10 minutes. As the water cools, you will need to add more hot water to maintain the fog effect. As a rule of thumb, one pound of dry ice will create 2-3 minutes of fog effect.
