Wraparound corkscrew
From Wikipedia, the free encyclopedia
The wraparound corkscrew is a roller coaster inversion by Arrow Dynamics. It begins as a corkscrew, then transforms into a 180-degree downwards curve. The defunct Drachen Fire at Busch Gardens Williamsburg was the only coaster to ever have a wraparound corkscrew; this element was incorporated into the coaster’s first drop. The Drachen Fire has since then been torn down.
