The Beauty of Pendulums

My friend Frank let me know about this cool video showing pendulums oscillating in and out of sync with each other. Watching phenomena like this one shows how some of the simplest things in nature -- heavy weights swinging from a cord -- contain magic and wonder. And, of course, I would be remiss if I didn't mention that the Exploratorium has long had a similar device, called Pendulum Snake.
