The Spin Cycle is an obstacle in the Wipeout Zone that consists of a rotating wheel, and three support beams full of foam. There are two options: The first option is to run along the bottom of the obstacle, and jump off the side, and the second option is to hang onto the support beams, and jump off. The longer it takes to complete the spin cycle. The trick to this obstacle slowing down is that it makes the walk along the bottom easier, but it makes the trip to the top, and down take more time. It is currently one of the toughest, and most dangerous obstacles on wipeout. In S3E17 there was balls instead of foam, but it still made it hard for the contestants. What is the foam made of?
