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.

Pi Has Your Number
This exhibit features a 12-foot long poster containing over three million tiny digits of pi. A computer at the exhibit lets you look up the position of any number sequence while a sliding magnifier can be positioned for you to see the sequence for yourself.
Strange Attractor
Magnets in the pendulum and the disks transfer energy back and forth, making the pendulum swing in unpredictable ways.
