Tilt-a-whirl

Tilt-A-Whirl is a flat ride similar to the Waltzer in Europe, designed for commercial use at amusement parks, fairs, and carnivals, in which it is commonly found. The rides are manufactured by Larson International of Plainview, Texas.

The Tilt-A-Whirl is a platform-type ride, consisting of seven freely-spinning cars that hold three or four riders each, which are attached at fixed pivot points on a rotating platform. As the platform rotates, parts of the platform are raised and lowered, with the resulting centrifugal and gravitational forces on the cars cause them to spin in different directions and at variable speeds. The weight of passengers in these cars (as well as the weight distribution) may intensify or dampen the spinning motion of the cars, adding to the unpredictable nature of the motion.
