The Backyard Scientist outfitted a liquid nitrogen canister with a release valve that basically turns liquid nitrogen into a freezing squirt gun death weapon (the pressure makes the liquid nitrogen shoot out pretty strong). He pitted it up against a flame thrower to see how long it would take for the liquid nitrogen shooter to win and it’s quite the battle. There’s also tests of the liquid nitrogen gun with other objects like flowers, a flaming laptop, and even a human.
