What would happen if put a cut a arisole can open?

it will explode. don't try and set it on fire either, if you were thinking of doing that. :)

Same thing that happens to a balloon, just with metal, instead of nice soft rubber. I would not try this, flying metal bits exploding out under pressure are not exactly safe.

It could very easily kill you! Don't be an idiot and try something like this.

These cans use gas under pressure to push the liquid out [usually butane the same as disposable lighters] A tiny hole in the top will release a the gas which sucks heat to expand. this will freeze skin and leave a nasty sore that takes weeks to heal. a hole in the bottom will squirt the liquid- then the gas. Larger holes will send it spinning or even flying off the ground, spewing liquid everywhere {eye protection recommended} at this point any handy flame or spark can give you a really spectacular fire. the earlier post had good advice------ DON'T TRY THIS AT HOME
