Foucault's Pendulum 38cm

The Foucault's Pendulum is a simple pendulum apparatus with a sand bath at the bottom. When set in motion, it gently "writes" an ever-changing geometric pattern. The patterns get bigger then smaller then bigger again as the arc of the pendulum also changes. You're sure to marvel at the geometrical designs that it comes up with!

14.9" high (38cm). Ages 8 and up.
