‘Cause you’re hot then you’re cold,
You’re yes then you’re no.
You’re in then you’re out,
You’re up then you’re down…”
Pardon my cheesy intro, we know that’s a lyrics from Katty Perry song’s “Hot N Cold”. And speaking of hot and cold, have you ever wondered which elemental force would emerge victorious in a heated battle between a flamethrower and liquid nitrogen freeze gun? Well, basically, it’s a question of who would win hot or cold.
Liquid nitrogen is used for many cooling and cryogenic applications. Flamethrower is to burn up. But in this clip, the Backyard Scientist carries out an experiment by tricking out a liquid nitrogen canister with a release valve that makes it shoot out like a fire extinguisher, and then pitting it head-to-head against a makeshift flamethrower. The result is really amazing! See it for yourself!
