Dry Ice Experiment

Friday was our dry ice experiment day. We placed a piece of dry ice in a bowl of warm water and it made a cloud of water vapour fog.  It looked like smoke.
We placed a piece of dry ice into a metal bowl and put a spoon onto the ice. Immediately the ice began to scream.

Dry ice is not frozen water, it is frozen carbon dioxide. We put some dry ice into a glove and watched as the carbon dioxide sublimated and blew up the glove.

We tried putting dish washing liquid in with the dry ice and made bubbles filled with carbon dioxide.

We used the carbon dioxide gas to blow the candle out.

We blew big bubbles filled with vapour...

... and tried to get them to sit on the carpet.
