  1. My physics teacher did this experiment once, but she was too afraid to do it herself so she got a boy in my class to do it for her. The only issue was that she didn't explain what was going to happen and started to tease him a bit when it didn't pop, then he pushed harder, the balloon popped, and he got a bed of nails in his hand. This is why you have to learn the science BEFORE you get to play with it.
