Today we went to Calvin Collage to see a presentation on Chemistry. It was really cool. There was a lot of fire and loud noises. What is thought was really cool was that nail polish  remover makes Styrofoam disintegrate. That was really cool! Another thing was  they  put a rubbing alcohol in a bowl and light the rubbing alcohol on fire and had  spray bottles of a whole bunch of elements on the fire and made it a whole bunch of different colors!
