So here's another idea that has had me wondering. I've noticed in a few movies that there will be a fight scene on an upper level of some skyscraper and during the fight scene the guy throws a chair or something through the window then jumps out afterwards into some water below. Now call me crazy here, but I'm just imagining that all that glass has fallen down already with the chair and is waiting on the water for you to jump into it. In my mind I'm imagining some sort of cheese grater like effect when you hit the water. Am I wrong here or wouldn't this really happen? Someone tell me.
