Foucault’s Pendulum

Watch the rhythmic motion inscribing beautiful patterns into the sand and be mesmerized. The pendulum rocks through the fine sand it gently ‘writes’ an ever-changing geometric pattern, which changes based on the arc of the pendulum.

The simplicity of a pendulum belies its scientific importance, as it has been used to demonstrate a plethora of principles, including the rotation of the Earth, and has been used to detect earthquakes for over a millennium.

This pendulum stands 38 cm tall.
