The program opens at Geauga Lake Amusement Park in Aurora, Ohio (just outside Cuyahoga County). Walker rides the rotor to explain ""centrifugal force."" In a neighborhood playground, he uses a simple merry-go-round to discuss the difference in speed when a rotating body has its mass spread out or pulled in. He takes angular momentum one step further, spinning around on a rotating chair with a spinning bicycle wheel in his hands. In the studio, Walker illustrates judo and aikido moves with a partner. He also illustrates the differences in spinning a hard-boiled egg vs. spinning a fresh one. Finally, Walker shows how a diver uses torques to land in the water in a certain way.
