Design[edit | edit source]

The entire layout

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]

The cars seat a total of 8 riders. 4 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.
