Ice Melting Kit

This kit is great for all doubting Thomases in your elementary through high school classes. Fast, fascinating and easy. This kit includes: Two black-colored blocks with rim for holding melting ice cube in place. The "cooler" one is of aluminum, which is an excellent conductor of heat. The ?warmer" block is of plastic foam, which is a very poor conductor of heat.
