Chaotic Pendulum
The visitor gives an initial twist to the pendulums with a protruding knob. Intuition says that the resulting motion of this system should be, if not simple, at least predictable. Intuition, however, does not work with this device since its motion is chaotic, extremely complicated and long-lived.

Coupled Pendulums
Start one of these two pendulums swinging and soon you’ll see the other pendulum start swinging, too. Keep watching and you’ll see the two pendulums take turns, alternately swinging energetically and coming to a near standstill.
Downhill Race
Believe it or not, when objects roll downhill, it’s not their weight or size that determines their speed—it’s how their weight is distributed.
Pedal Generator
