Create amazing patterns with Foucault’s Pendulum. This simple device hangs from the ceiling and is based on a design originally conceived as an experiment to demonstrate the rotation of the Earth. The pendulum gently writes complicated geometric patterns on the sand, staring bigger then getting smaller as the arc of the pendulum changes. Sand patterns are written and rewritten for over five minutes. Adult supervision recommended. Sand tray measures 40cm d. Ages 3yrs+
