Dry Ice Soap Tower Bubbles – Science Experiment for Kids at Home
Explanation: Dry ice is solid carbon dioxide and when it is added to warm water it turns into carbon dioxide gas instantly. Dry ice turns directly into a gas without going through the liquid state, a process called sublimation. So, when it is added to a solution of soap and warm water, the solution starts ‘bubbling’ and you have soap bubbles filled with carbon dioxide and water vapor inside!
These bubbles look white due to the gas inside! The bubbles start climbing up very fast and you can build a tower of soap bubbles. Try bursting the bubbles and you’ll see the gas popping out!
