Gravitron

The Gravitron (later marketed as the Starship 2000 and the Starship 3000 and currently as the Starship 4000) is an amusement ride, most commonly found as a portable ride at fairs and carnivals. The Gravitron first appeared at Morey's Piers in 1983 and quickly became a fixture at amusement parks in many countries. It is a modification of an earlier ride called the Rotor. The ride was originally designed and manufactured by Wisdom Industries, though several examples of the Gravitron were produced under license by ARM in the UK and Ferrari in Australia.
