Looping Pendulum Long Exposures

If you attach different-weight objects to a string and hang them over a bar, the lighter object can prevent the heavier one from hitting the ground when dropped. As this happens, the rope spirals around the bar. Science teacher Bruce Yeany attached LEDs to the objects and captured long-exposure photos of this fascinating looping pendulum action.
