Liquid Nitrogen Freeze-Ray Vs. Flamethrower 液氮比喷火器

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!

我做了一个冻结射线！林基本上一位诚实的邪恶天才现在。冻结你的猫，女朋友，或花，可能性是无止境的..！等到没有，这就是它。 PS危害想着起诉我使用他们的音乐之前，记得是谁现在有冻结射线！凯文：1 - 亚历克斯：0
有关枪的一些注意事项：
有用于皮肤科冻结疣和皮肤癌关闭商业液氮枪。出售我液氮的家伙告诉我他们。他说，他们有保持在大约70PSI的压力的压力释放阀。的问题是它很难作出热水瓶这就是还额定压力，因为你必须在烧瓶的内部的压力，然后直接在另一侧的真空度。它们是脆弱的，价格昂贵。我试图把一个镍铬合金发热体保温瓶内压力增加，但它结束了没有工作很大。摇晃的方式作出更大的压力热水瓶！
