Corkscrew is an Arrow Dynamics corkscrew model located at Silverwood Theme Park, and previously operated at Knott's Berry Farm under the same name. Not to be confused with the first vertical loop on a roller coaster, which was Revolution at Six Flags Magic Mountain in 1976, Corkscrew is considered to be the first modern inverting roller coaster and held the world record for most inversions on a roller coaster.[2]

This Corkscrew is the prototype which was erected at Arrow's factory in California.


From 1975 to 1989, the coaster operated at Knott's Berry Farm. After it was dismantled, it was moved to Silverwood Theme Park. Corkscrew would open at its current location on June 22, 1990.[3]
