Corkscrew is a roller coaster in Gemini Midway at Cedar Point. It's worth seeing on a time-permitting basis. The minimum height to ride is 48 inches.
The first coaster in the world to go upside down three times. Designed by Arrow Dynamics, it was built in 1976. It features an airtime hill, a vertical loop and a double corkscrew that turns riders directly over the midway.
