Bicycle Wheel Gyro
Tilt a spinning bicycle wheel while you’re sitting in a swivel chair and—surprise—you’ll start spinning in circles, too. You can also witness the same phenomenon here by hanging a spinning wheel from its axle.

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.

Turntable
Experiment with rotational motion (and collisions) here at one of our most addictive exhibits. Disks and balls moving on and across this spinning table swoop and veer hypnotically—and also reveal why storm systems often follow curved paths on weather maps.

Vortex
A twist of a knob sets water jets in motion, causing water in this giant cylindrical tank to spin. Soon, a tiny vortex appears at the surface, gradually swelling in size as it snakes downward.
