Corkscrew (Valleyfair): Corkscrew is the name of a roller coaster at Valleyfair in Shakopee, Minnesota featuring one vertical loop and two corkscrews.  Built in 1980, Corkscrew was planned to reflect the design of its sister roller coaster Corkscrew at Cedar Point.  It is notably one of the first roller coasters to feature a double corkscrew, as well as a vertical loop.  The main differences that the Valleyfair model has is the addition of a finale helix and the omission of the camelback before the loop.  Until the hypercoaster Wild Thing (the fifth highest and fastest roller coaster in the world at the time it opened in 1996), Corkscrew was the only outdoor all-steel roller coaster in Minnesota.

Roller coaster phobia: Roller coaster phobia is a colloquial and slang term describing an individual's fear of roller coasters.  While roller coasters are the most popular theme park attraction, certain people feel nauseated, afraid, dizzy, or unsafe when riding roller coasters.  In the majority of cases, this fear is related to acrophobia, claustrophobia, or a traumatic event.  Roller coaster phobia can be overcome relatively easily, the best cure being going on the tallest/fastest roller coaster before riding roller coasters of a lesser magnitude.  Roller coaster phobia has been linked to previously experiencing an accident, vertigo, and fear of heights.  In rare cases, riders may be afraid of roller coasters due to a painful ride, tight restraints, being thrown around in the restraints, and excessive g-forces on the body of the rider.
