Human Squirrel Cage (Sep, 1954)

This looks like a hell of a lot of fun.

Human Squirrel Cage

THRILL ADDICTS registered their screaming approval of a German-made fun machine introduced at Chicago’s Riverview Amusement Park this summer. Little cars circle a drum 27 feet in diameter which supports five circular tracks. The cars are loosely attached to the tracks and, by operating a foot pedal, the rider can lock his car to the track. As the drum revolves at about 15 miles per hour, the cars go around with it. Timid riders can release the brake pedal and their cars merely rock back and forth. But braver souls press the pedals and make like squirrels in a squirrel cage.
