Dry Ice Bubbles
Questioion: What happens when you add dry ice to soap and water?
Hypothesis: The dry ice creates a gas and fills the water with air and make bubbles or the water will turn to vapor

Safety ProceduresDry ice can burn skin. When using dry Ice, always wear gloves. The dry ice should only be handled by the person showing the experiment.
Material 1: Gloves Material 4: Ice Tongs |
Procedure: 1. Start with water in a container
2. Add dish soap 3. Add food coloring just to make it interesting 4. Place dry ice in the water 5. Watch the bubbles flow 6. Pop them and smoke comes out! Special Needs: Need to be placed near a sink |

The Science behind it
Dry ice changes directly from a solid to a gas, without ever being a liquid. This process is called sublimation. When dry ice is put in water it speeds up the sublimation process, creating clouds of fog that fill up your dry ice bubble until the pressure becomes too much and the bubble explodes, spilling fog over the edge of the bowl. Dry ice is sometimes used as part of theater productions and performances to create a dense foggy effect. It is also used to preserve food, freeze lab samples and even to make ice cream!
