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?

A lot of pressure.

How much is a lot of pressure??

It has the skill to save the life of a mother, or a child! BUT ONLY ONE! The pressure is on, shaving can, the pressure is on!

thats a cool site you posted

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.

I love that site.

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.
