Foucaults Pendulum: A simple device that hangs from the ceiling, conceived as an experiment to demonstrate the rotation of the Earth – while also making intricate patterns in the sand.
This is a scientific and artistic item and makes an unusal and interesting gift.
Hangs 134cm tall. The sand tray is a little under 40cm in diameter. Set the pendulum swinging to create the complicated geometric paterns for approx 5 minutes.
