Dry ice dances
How to make ice dance
Cold but elegant chemical dances!
Attention! All experiments are performed by professionals. Do not attempt.
Dry ice is solid carbon dioxide at a temperature lower than –78 °С (–108 °F). But the room’s temperature is about ~100 °С (~200 °F) higher! Under these conditions, the solid carbon dioxide rapidly becomes gaseous, which leads to the formation of gaseous layers under its solid pieces. This causes the solid pieces to remain on the water’s surface! Hovercrafts operate on a similar principle.
