Roll the Zorb Rotorua–Rotorua Bay, New Zealand
Remember that college party where someone rented inflated sumo suits so participants could bounce off each other with impunity? This is like that, but only crazier. In Zorb, one climbs into an inflatable ball through a… well, a sphincter of sorts. The ball is clear with tons of air holes. Zorbing, as they call it, is where one rolls downhill in the ball like an overgrown hamster. Participants describe the experience of feeling weightless. The risk is super low, but the experience is like nothing else in the world. Plus, when you’re done, you can explore the land where they filmed the Hobbit.
