In mathematics, in the area of dynamical systems, a double pendulum (also known as a chaos machine) is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior.
In the video below, inventor and author William Gurstelle offers instructions on building a simple chaos machine for classroom study or just for personal enjoyment.
More information is available here, and a computerized animation of a double pendulum is here.
