Our Story

The Swinging Sticks was invented by two German friends intent on visualizing a perpetual motion machine. Although they knew such a device was theoretically impossible, their desire was to demonstrate the concept. They spent months improving and tweaking small details to minimize the friction and maximize efficiency. By the time they had finished they built a new kind of double pendulum kinetic sculpture – The Swinging Sticks.

Since the early 2000’s, The Swinging Sticks have grown in popularity, which culminated in 2010 when they were featured in the film Iron Man 2. The director, Jan Favreau, had seen The Swinging Sticks while on vacation and decided to include it in his upcoming blockbuster. Since then, The Swinging Sticks have become internationally recognized as one of the finest kinetic energy sculptures in the world.

In 2010, The Swinging Sticks became even more popular after Jan Favreau, the director of Marvel’s Iron Man 2 decided to use The Swinging Sticks in a scene between Pepper Potts and Tony Stark played by Gwyneth Paltrow and Robert Downey Jr.

Since Iron Man 2, The Swinging Sticks have continued to grow in popularity and is now established as one of the finest kinetic sculptures in the world.

Beautiful Mathematics

The Swinging Sticks seem to defy gravity and turn logic upside down. How can they endlessly swing without ever pausing? How can their sticks circle so fluidly?

The answer lies in calculus, specifically a series of differential equations solved using the Runge-Kutta method for numerical analysis.

The animation on the left demonstrates the mathematics behind a compound double pendulum. The Swinging Sticks obey a modified version of this movement that mesmerizes while maintaining the underlying chaotic nature.

As shown in the animation, even a very small variation in starting height has a dramatic impact on the trajectory

Impeccable Craftsmanship

The Swinging Sticks contain multiple sensors that measure the speed of the rotating rod and an electric coil to speed it or slow it down. The arm contains a powerful neodymium magnet that will repel and assist the unpredictable chaotic motion.

A key principle in physics states that moving electrons will generate a magnetic field. This magnetic field is the driving force behind the sculpture.

As long as the magnetic field is being generated, the process will be repeated (always with a slight variation). The position of the magnet, weights, and coil must be extremely precise to function with maximum efficiency and elegance.
