The nail balance challenge has been around for years, I remember seeing it when I was in high school, but here is a new twist to it. The challenge is a simple demonstration of balancing a dozen nails by arranging them in a sequence that holds them together and then supporting the entire group above it's center of gravity. . So here is the challenge done with a variety of nails from sizes of 5 inches down to less than an inch. As they get smaller it does become quite a bit harder. What is new is that I've tried to do a variation of the trick by reproduce the challenge with pencils. It can be done, but a slight alteration is needed to the heads of the hanging pencils.
