The silver rings of this cool Planet Kinetic Mobile gracefully orbit a central sphere. The motion is continuous and, at first glance, impossible to fathom.
The secret lies in the base. A battery-powered motor spins a powerful magnet, which exerts a variable force on the pendulum weight attached to the outer ring.
Even when you know exactly how it works, the perpetual, rhythmic movement and gravity-defying structure will fascinate you.
