OMG im on GoPro! https://www.youtube.com/watch?v=r3RGO... my fire sword!

I made a freeze ray!  Im basically a bonafide evil genius now. Freeze your cat, girlfriend, or flowers, the possibilities are endless..! wait no, thats about it. PS before Jeopardy thinks about  suing me for using their music, remember who has the freeze ray now! Kevin: 1 - Alex: 0
Some notes about the gun:
There are commercial liquid nitrogen guns used by dermatologists to freeze warts and skin cancer off. The guy that sells me liquid nitrogen was telling me about them. he says they have a pressure release valve that keeps the pressure at around 70psi. The problem is its hard to make a thermos thats also pressure rated because you have a pressure on the inside of the flask, then a vacuum directly on the other side. They are fragile and expensive. I tried to put a nichrome heating element inside the thermos to increase pressure, but it ended up not working that great. shaking the thermos made way more pressure!

the resaon the liquid nitrogen puts out the fire has nothing to do with the fact that its super cold.(-320.8 F) It just displaces all the oxygen which takes away one of the three elements you need to make a fire..

Lol. I knew the nitrogen gas would beat the flames because it would suffocate them, but this video and the slow mo were amazing. xD

Does the fact that it's cold have anything to do with this...? Seems like dousing a fire with an inert gas would put it out regardless of the temp.

Is the nitrogen gas just starving the flame of oxygen so without knowing how super heroes produce heat or cold this is not going to prove who would win? ;-)

Oh.... really? No. It no to mysterious "cold" won this deal because cold is not any trouble for fire!
It NO OXYGEN won with fire. Because fire need oxygen to "work".
Clear enought?

I don't think what put out the fire was the cold, more like the vapor choking the fire to death
