497. Quickie Web: Video: Chaotic Pendulum September 7, 2007Posted by Matt Fleming, PsyD in Product, Quickie Web, Video.
Witness random motion in this video clip. At first, the pendulum swings typically. But once the joint is loosened, the second segment flails about in a jerky dance. This clip would be even more fun to watch if LED lights were placed on the joint and the tip, with the lights off (in video, and as photographs with prolonged exposures). Via Make (where you can also learn to make your own).
