This simple 38cm hanging plastic pendulum with a black stand is the perfect size to sit on your desk, with its rhythmic motion inscribing beautiful patterns in the sand.
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.
