Mesmerizing and addictive! More than an elegant desktop toy (although it is that too!), Foucault's Pendulum demonstrates real science. Secured on its stand, the all metal pendulum converts kinetic energy into potential energy.

The patterns get bigger then smaller then bigger again as the arc of the pendulum also changes.
