Fun with Dry Ice
Posted March 18, 2009on:
Long story short, we went to Penn State, visited the nuclear reactor, toured the school, ate lunch, and purchased two coolers full of ice cream. It’s a 3+ hour ride home, so we also purchased dry ice for $0.75 per pound.
The next day, there was still quite a bit of dry ice left over, so I did this demo for each of my classes. I put the dry ice in water and watched the “smoke” pour out. I had another beaker with water and some dish soap. Adding dry ice to that makes a huge pile of bubbles that are cloudy and evaporate on contact.
The best part was that the kids suddenly had a ton of questions. They wanted to know what would happen if they inhaled the gas, if the water was safe after the dry ice was gone, and lots more. Don’t forget to play, it’s a great way to learn.
