Scream!

Scream is a steel roller coaster at Six Flags Magic Mountain. Manufactured by Bolliger & Mabillard, the Floorless Coaster model was the park's sixteenth roller coaster and is located in the Screampunk District area of the park. The 150-foot-tall ride consists of a series of roller coaster elements including seven inversions ranging from a zero-g roll to interlocking corkscrews. The ride is a mirror image of Medusa at Six Flags Great Adventure.
