Linda rotates Mark
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Linda puts Mark in a desk chair and hands him a leaf blower. She starts him spinning, intending for the leaf blower to keep the momentum of the chair going, which it does for a while. Mark rotates 41 times, and Linda comes third.
