Next Phenom
How to do it Try to fold different sized pieces of paper in half more than eight times. Try it with a small piece and very, very large piece. See! You can't do it! Each time you fold the paper, the stack you are folding becomes thicker. After a while, your arms aren't strong enough to fold it anymore. It's kind of like trying to cut a thick stack of paper with scissors - you just can't do it if the stack is too thick.
