Freeze your cat, girlfriend, or flowers, the possibilities are endless..! wait no, thats about it.
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!\n
