Bubble Experiment: Boiling Water and Liquid Nitrogen Reaction

What happens when boiling hot water meets ultra cold liquid nitrogen? In this video, Museum Educator Locke explains how liquid nitrogen boils at the super cold temperature of -320 degrees Fahrenheit. When forced to combine with the boiling hot water, the liquid nitrogen rapidly expands to a gas, causing an explosion of water vapor. When a little bit of dish soap is added to the mix, we get big bubbles filled with white water vapor. This exciting experiment is both educational and fun!
