Dry Ice Floating Bubble - Sick Science! #058

In this episode of "Steve Spangler Science" videos, the gas produced by the sublimation of carbon dioxide dry ice creates a nice, fluffy cushion in a bowl of water. Since it is less dense than a soap bubble and cool enough to keep it from popping quickly, the bubble hovers ghost-like on the cushion. This it a good way to demonstrate heat energy, sublimation, and density.
