Daredevil Nik Wallenda  thrilled the crowds at Darien Lake recently when  he rode a motorcycle on a wire over the Lake. As if that wasn't nerve wracking enough to watch, he also had two people suspended by wires under his bike. When the bike starts flipping and that performer underneath flips around and around, my head started to spin. Watch and see if you start to feel a bit dizzy too! How do you do stunts like this?
