Fastest Roller Coaster

While it never leaves the park, Kingda Ka roller coaster at Six Flags Great Adventure amusement park in Jackson, New Jersey, is recognized as the world's fastes­t roller coaster.

­Opened in 2005, the Kingda Ka is a hydraulic launch rocket coaster that reaches its top speed of 128 miles per hour in just 3.5 seconds. Its 456-foot-tall tower is also the world's tallest for a coaster. Built by the Swiss ride manufacturer Intamin, the Kingda Ka uses an over-the-shoulder safety restraint system to keep riders in their seats, but there's no guarantee it will keep their lunch in their stomachs.
