Chaotic Double Ring Pendulum: a fun design on the chaotic double pendulum. Interesting and intricate motion arises from a simple assembly of two physical pendulums (one attached to the end of the other) with the kinetic energy of the system moving back and forth between the two rings until friction damps away the energy. Chaotic motion is characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes ea
