So how much pressure are we talking about? Shaken can of soda or grenade? Are they going to explode or what? I recently saw an idea about freezing shaving cans and placing the contents somewhere, as they thaw out they expand, and expand ALOT aparently and this makes for a funny prank. So whats the scoop?

I suppose explosion is a possibility. *nod*

I think that if you shook the can up and tossed it on the ground hard enough you might do some damage wit hcan shrapnel.

My friend's dad said that his friend sprayed hairspray and lit it as it was spraying and it blew up and he doesn't have a hand anymore. His HAND, man.
