As a penny balances precariously on the hook of a wire hanger, you might think any sort of movement would send the penny flying. With a bit of physics know-how, you can spin the entire hanger around in a circle without losing the 1¢ coin. When it comes down to it, you just need to thank Sir Isaac Newton.
