Liquid Nitrogen Freeze Ray vs Flamethrower

by Conner Flynn

What’s cooler? A flame thrower or a freeze ray? I prefer flame throwers, even though they’re not literally as cool. But which would win in a fight? The Backyard Scientist decided to test it out.

He constructed a homemade liquid nitrogen “freeze ray” that uses the pressure of the nitrogen turning from a liquid to a gas to create a powerful cold spray. After freezing some flowers, he wondered if it could stand up to a flamethrower. So the two gadgets had a showdown.

Spoiler alert. The freeze ray wins, but it should be noted that he moved his  freeze ray closer to the flamethrower, while the flamethrower was stationary. Therefore, I demand a rematch.
