In this "Quick Clip," I tried dunking inflated balloons into a container filled with liquid nitrogen until they were completely flattened and seemingly destroyed. Once out of the liquid nitrogen, the balloons come back to life and reinflate on their own—without even touching them!
WARNING: Use of video content is at own risk. Liquid nitrogen is extremely cold (-196°C/-321°F) and can freeze skin on contact. Liquid nitrogen should only be handled by those who understand the risks, and are skilled in dealing with extreme temperatures.
This science experiment was inspired by a science demonstration my wife and I saw while visiting the Chicago Museum of Science and Industry.
