Design[edit | edit source]
The ride has a short layout, with no lateral turns. The cars spin, and the amount of spinning is affected by rider's weight.
Trains[edit | edit source]
3 cars. Riders are arranged 4 across in 2 rows for a total of 8 riders per car. There are 4 riders on each side of the track, with half facing forwards and the other half facing backwards. The 4 seats on each side of the track rotate independently from the opposite side.
