The Physics:

Made famous when featured on the desk of Pepper Potts in Iron Man II, this sculpture displays chaotic motion that is both pleasing and memorizing. Based on the physics of the coupled physical pendulum, the motion of the rods is extremely sensitive to the initial conditions upon when they were set into motion, the essence of the technical term chaotic motion. The intricate motion is maximized by careful consideration of the location of the pivot joints, and by weighting the rods just right.

The rods are kept in motion by an electromagnetic kicker circuit in the base that pushes on a magnet in the tip of the longer rod. The essence of a basic kicker circuit is quite simple and includes the following components: a coil which serves as an electromagnet, 4 AA batteries to energize the coil, and a transistor as a switch. I have not disassembled the base of my sculpture, but I'm quite sure the circuitry is similar (and more advanced) to some of my other physics toys such as the Mystery Top and the Space Wheel that use the design described in this 1974 patent: Novelty Electric Motor.

This kind of kicker circuit is very efficient with no moving parts (except for the sculpture itself). This efficient use of electricity, along with careful engineering with respect to balance and minimal friction, leads to a battery life of up to 2 years.

The Swinging Sticks Desktop Toy: a desktop version of the famous Ironman double pendulum for just $98 US. Use this code to get free world wide shipping (coupon code = FUNSHIPPING) on all purchases of The Swinging Sticks Desktop Toy on @Geelongshopcom. This kinetic art device is the ultimate physics toy, and was featured in the movie Iron Man II (sitting on the desk of Pepper Potts). The physics magic of this device displays the essence of chaotic motion with coupled pendulums- the placement of the rods' axes of rotation are engineered to exhibit the widest range of interesting motion. Four AA batteries and a simple kicker circuit in the base gives a push to a magnet in the end of the large rod keeping the system in motion for over a year! ➡️ Follow the link in my profile for info on where to buy this and many other amazing items featured here on @physicsfun #physics #physicstoy #pendulum #coupledpendulums #coupledharmonicoscillator #harmonic #physicalpendulum #chaos #chaostheory #nonlinear #nonlineardynamics #strangeattractor #science #kinetic #kineticart #swingingsticks #theswingingsticks #ironman #pepperpotts #scienceisawesome
