Mall of America: Atomic Collider (aka Tumbler or Fireball)

The Fireball ride at Mall of America in Minneapolis. Knott's Berry Farm used to have the same ride, calling it the Tumblr, but it's since been removed. As far as I know, this is the last one in operation in the US.
FYI... only some of the arms reverse. When riding, note that each arm is numbered via the gray power box in the center (you can't make out the numbers in the video, but they are there). The even numbered arms reverse, and the odd numbered arms only go forward.
