Liquid Nitrogen

Liquid nitrogen is an amazing substance. When it is mixed with hot water it makes a mist. Dry ice has the same effect. Since matter contracts when it is cold, when a balloon is shoved in liquid nitrogen, it gets smaller. When it is taken out it gets bigger. There was a show at the LSC. DO NOT TRY THIS AT HOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
