just curious...have you ever tried to crush a can of unopened soda with just your hands? i've seen this done a couple times

Nope, never have but I have seen people with much weaker grips than I who could crush them easily.

How about ripping a phone book in half?

are you talking about ripping the can in half with 2 hands?
or crushing the unopened can with one hand? So far as I know there is only one man who can crush a can like this.

the 600 lb estimate was on manfred hoeberl's site. isnt that joe guy the one that rolls iron frying pans in his hands, or do a lot of people do that now?
Joe Kinney is awesome at grip work. Awesome. It has next to nothing to do with body strength at all though.
Remember...if you shake up the can...it increases the internal pressure and makes it much easier to crush. I have seen guys crush many soda cans that could not walk with a pair of 250 pound farmers walks... They can also roll up frying pans too...easily.

What are you talking about? Think about it in terms of specific numbers. If the two arms are applying 500 newtons of force on the can, while the gas applies 100 newtons of force vector in the opposite direction, than you are really only applying (500-100) = 400 newtons of force to the can.
If the internal perssure due to gas is increased then it becomes much harder to crush the can.

think about it this way revrex. you have a ballon and u blow it up to about the size of your head and you use x amount of force to squeeze it with your hands to pop it ok. or you can take that balloon and put more air in it and it will take less force with your hands to pop it

Here we go.
The atmospheric pressure of oxygen is much less than the pressure inhibited by the CO2 and whatever other additives they put in regular soda. Therefore this pressure is not even noticable to a human when he/she tries to crush the baloon. The only way why it SEEMS like its easier to pop a baloon thats full of air is because you are displacing the air inside, which in turns pushes onto outer walls of the baloon and eventually the material bursts open.
A soda can is a different example, you have to apply an outward force in order to crack it. The soda can does not change form to an extent that baloon does, and therefore using the gas inside to your advantage is impossible.
You are pushing on the can, the gas is pushing against your hands.
When you want to push someone, but that person resists you, is it easier or harder to move him/her? Thank about it in this kind of sense!

Also, when you blow up a balloon, you are stretching it, making the wall of the balloon thinner. This does not happen with a coke can.
Well...I do know that it is MUCH easier to bust a soda can when it has been shaken up...

I want to try it....but im a bit worried about getting cut or something....i dont think i could do it......but just imagine going to partys and doing it.
I have only seen videos of single handed can crushing. I think two of them were strongmen competitors....and the other one was said to be lee priest...but there was no footage of his face

Wear some sort of gloves. Most of the time it busts out of the top of the can anyway...

ohhh i thought you guys meant crumbling a soda can as if you would crumble an empty can with your arm.
But if you want the cap to blow out, than yea shaking it up will definetely help. Force = Pressure * Area, so by squeezing it you reduce the area of the can, but pressure has to increase to compensate, and soon enough the cap will pop out.

eggs...
I didn't see if someone mentioned this, but it is impossible to crush an EGG in your hand. It's crazy! If you hold it on your palm and put your fingers around it uniformly and squeeze as hard as you can- not with your thumb poking into it or anything, is is impossible to do. ITS FREAKIN NUTS. Me and my roomate tried it- He is a 250lb BIG motherfucker, so trust me, you can't do it...
Give it a go, it will surprise the hell out of ya...

Try crushing a can? lol...I may do that this weekend...
I bent a 5/8" thick piece of cold rolled steel last night that my father bought me.

The pressure in a can does not increase when shaken. Sorry guys.
