Today I was able to play with dry ice and study it's properties. I have previous experience with dry ice but it was nice to experiment with it once again. The sub-zero ice-like substance was very fun to experiment with. When dry ice "melts", it skips the melting part entirely and turns to a gas. Because the air around it is much warmer (room temp), dry ice has a constant "melting" or evaporating carbon dioxide gas. When put in something warmer than room temp, it gives off even more carbon dioxide gas.
For an experiment, I put a chunk of dry ice in a balloon, and doing so made it slowly self-inflate. I then put quarters on the ice and let them freeze. It made some funny sounds. Putting dry ice in warm water was fun to see all the vapor pour out of it, but eventually it became freezing water.
