I worked for Coca-Cola on the container floor in my teens. It's insane how much small point pressure a plastic bottle can take. http://www.youtube.com/watch?v=4

I worked for Coca-Cola on the container floor in my teens. It's insane how much small point pressure a plastic bottle can take. http://www.youtube.com/watch?v=49ScJUCqj98 http://www.youtube.com/watch?v=49ScJUCqj98 We had fun throwing 2L bottles on the floor. If they struck the floor smack on the bottom of the bottle they would bounce back up. The impact increases the pressure inside the bottle. We'd do this a couple of times, then the last drop would be top down, hopefully breaking the cap launching a coke powered rocket to the roof! That's the quickest way to break the bottle without using tools I think.
