Double Pendulum
A double jointed pendulum hangs from a rod. Swinging the pendulum with high energy results in motion that cycles chaotically between normal modes. Swinging it with low energy results in more predictable motion.
When viewed under black lights, it is easy to see that the first joint of the pendulum travels in a semicircular path, while the second joint follows varied, unpredictable trajectories.
