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

Magnetic Chaotic Pendulum: this beautifully designed “perpetual pendulum” has been in my collection since 1990. The ufo shaped bob has a magnet embedded in it and the base has a battery and simple coil circuit that gives the bob a tiny push each time it swings through the center. An array of 5 permanent magnets are also hidden in the wood base (wait for reveal with magnetic viewing film) and these magnets produce the chaotic motion- not random, but very sensitive to slight differences in initial

Double Pendulum Chaos: by orbdrop https://www.physicsfunshop.com/category/kickstarter A device to demonstrate the motion of mathematical chaos from a simple assembly of two physical pendulums (one attached to the end of the other). An LED light attached to the end of the pendulum is used to generate light trails captured by the app “Slow Shutter” allowing for a visualization of the chaotic motion. The physics of chaos is characterized by intricate orbits and extreme sensitivity to initial starti
