Supreme Scream

There's no complicated track here, just sit down, strap in and you're blasted 254 feet straight up, then plummet down at up to 50 miles per hour. They won't let you go yet, though - there's another bounce halfway back up before you're done. The whole thing is over in 45 seconds. G-forces range from 4.0 (on the way up) to -1.5 on the way down.
