My piece was inspired by a toy I had when I was younger that was made up of a hoop with colorful washers strung on it. If you spun the washers and the hoop just right, you could get the washers to hover on the side of the hoop. I built a much larger version and powered the hoop with an old typewriter motor hooked up to some pulleys I made. The hovering rings I made out of acrylic and polycarbonate, and each one has a magnet on the inside. Initially I thought the magnets were what made the hovering thing work, but I was wrong... it's a purely mechanical effect caused by the wobble of the rings as they fall in a helix around the hoop. As the hoop spins, it gives the rings a little lift. It's a pretty magical effect, and the noise the spinning rings make is great. My favorite part of the evening was watching how the hovering rings fascinated people and hearing their crazy explanations for why it worked.
