What are the pros and cons of liquid nitrogen?
That’s not even close to liquid nitrogen Those cans contain some inert gases and other chemicals that are relatively easy to compress into a liquid, but at room temperature under normal pressure they’re a gas, so when you spray it out of the can onto your hand, it evaporates nearly instantly, and it’s just like sweat evaporating off your body, but much much faster. You need to be careful as a can of that could give you frostbite if you were exposed to it a lot for a while The can becomes cold because a bunch inside of it evaporates when you spray some since the pressure drops inside for a moment, which is the same idea. The stuff doesn’t normally smell(inert gases!)but it’s made to smell by the manufacturer to discourage inhalation and consumption. It’s not safe to inhale, unless you dig paralysis and death Edit: The can gets cold because the pressure is released. He’s trying to imply just the release of pressure would cool it, but it’s not a gas! The only reason the things inside the
