Heebie Jeebies - 38cm Foucault's PendulumRegular price $49.99 Save $-49.99
As the pendulum rocks through the fine sand it gently ‘writes’ an ever changing geometric pattern. The patterns change size as the arc of the pendulum changes. The 38cm version has a black stand and 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. A fabulous gift for the ‘hard to buy for’ older child or adult.
