Sandpendel, a Desktop Foucault Pendulum Toy For Stressed Physicists

sandpen1.jpgStressed-out scientists can now relax with the Sandpendel, a mashup Zen sand-garden/physics-experiment desktop toy. Designed by Jürg Näf, the Sandpendel is based on Léon Foucault's famous 19th-century experiment that demonstrated the Earth's rotation. Details, plus another pic, are below.

Since, however, Foucault went to great lengths to abolish friction in the real device, we're a bit sceptical. Still, it produces pretty patterns and is way more novel than an old Newton's cradle, even if it costs a largeish €239, around $400. [Singulier via 7Gadgets]
