Teams are then strapped vertically spinning wheel with their heads trapped inside plexiglas boxes, and they must collect scorpions from the ground and put them into the boxes. In the final stunt, teammates must back cars down ramps on the ends of flatbed truck trailers and drive up onto the opposite trailer from which they started.
