Possibly the world's most terrifying ride, Insanity is perched on top of a skyscraper. An extendable arm dangles thrill seekers 900ft above the ground and 64ft out over the tower's edge before spinning them at forces of up to three Gs.

Also on the building is the Big Shot, which slings riders 921 ft above the tower in 2.5 secs and X Scream, which propels riders head-first 27ft over the building's edge.
