Liquid nitrogen spray can?

[madscientist (imported)]

When liquid gas leaves a bottle, it draws heat from the bottle & the bottle draws heat from whatever is near it. Therefore, it is safe to conclude that if one was holding a can of liquid nitrogen big enough to deliver enough N to actually lower scrotal temperature to the point where it would freeze, one's hand would freeze, too.

Re: lazers. A nice thought. Unfortunately, lazer is just another type of light which, unlike regular light, does not diffuse. Assuming that it takes 1000 watts of heat to burn through something you would need enough power to generate that with a lazer & that would take too many batteries to allow it to be portable.

try dry ice, easier to carry.

This is hypothetical (and probably a fantasy), but, is it possible to put liquid nitrogen in a can that a woman can carry in her purse?

Sorry, but this is a very bad idea. You can't seal a container of liquid nitrogen because it will warm up and reach explosive pressures. I once worked at a compressed gas company and they showed pictures of what compressed gas cylinders could do as they underwent "rapid decompression" ...

AND no woman wants to carry that much destructive power in her purse. A 357 magnun pistol would be kinder and gentler and easier to handle.

Seems to me that Nitrogen must maintain a state of -40F for it to maintain a liquid state.

Liquid nitrogen boils at -195.8 celsius, or -320.3 fahrenheit at one atmosphere. It's Propane that has a boiling point that is approximately -40 degrees. Liquid Nitrogen is kept in a dewar flask, which is just a thermos on steroids, for short-term storage in the lab and even then it still boils off, albiet much slower than it would in an uninsulated container.

You can carry liquid oxygen around in a dewar bottle, and you regularly see people who

need extra oxygen doing it. Who knows, your grandma may already have one.

If you were to spray the rapist with liquid oxygen his parts would freeze, then you can throw

a match and he will be incinerated.

rapist -> pile of ashes.
