Liquid Nitrogen Demonstration
Aaron Keller, Chemistry teacher, demonstrates the amazing properties of liquid nitrogen. He explains each demonstration in an understandable way. The temperature of liquid nitrogen is -196C (-321F). He explains how a dewar flask works. He pulls balloons out of a cooler, showing the expansion of a...

Hand vs. Liquid Nitrogen and the Leidenfrost Effect
I stick my hand (momentarily) directly into liquid nitrogen but don't suffer any injuries due to the Leidenfrost effect. The Leidenfrost effect is the formation of a gas barrier between a hot surface and a boiling liquid if the temperature difference is great enough. This gas barrier greatly slow...

Hand vs. Liquid Nitrogen - Revisited
I go back to sticking my hand into liquid nitrogen but remain uninjured due to the Leidenfrost effect. The Leidenfrost effect is the formation of a gas barrier between a hot surface and a boiling liquid if the temperature difference is great enough. This gas barrier greatly slows the heat transfe...

Goldfish in Liquid Nitrogen
A goldfish is frozen in liquid nitrogen, only to be 'magically' brought back to life! For everyone that is worried about the goldfish, it survived and was perfectly fine until we fed him and a few of his friends to our turtles. (Which is what they were bought for in the first place!)

Liquid Nitrogen Frozen Gummy Bear
Looking for more ways to obliterate gummy bears in scientific ways, Joanne freezes a gummy bear in liquid nitrogen. She also soaked a gummy bear over night to demonstrate the ability of gelatin to hold large amounts of water--and then she freezes that one too. She has a "control" gummy bear (not ...
