Mr. Freeze Reverse Blast is a roller coaster in DC Comics Plaza at Six Flags St. Louis. While it's not the best, it is also recommended. The minimum height to ride is 54 inches.
A Premier Rides LIM (Linear Induction Motor) launched roller coaster.
The ride catapults guests backwards from 0 to 70 mph in 3.8 seconds through a 190' tunnel and up into a 180 degree inversion that flips riders completely upside-down. This "Top Hat" element is followed by an over-banked turn and a vertical spike. As the train nears the top of this spike, it loses momentum and is pushed up the rest of the 200+ feet by another set of LIMs. The train then stops moving upward and falls down, running the entire course in a foward-facing direction.
Duration of the ride is approximately 55 seconds.
