Bright Square

Size: 400 x 220 x 500 cm
Material: Metal, Electrical Motor, Magnets.

On a large metal construction, tree pendulums are mounted. Each pendulum is held by magnets in a vertical position. Driven by a motor, a lever is pressing down on the pendulum arm. The potential energy builds up until the magnet can no longer hold it. The kinetic energy is released, letting the pendulum swing to the opposite side, where it is again held by a magnet.
