Walkin' a Tightrope

Nik Wallenda walks a 1,800-foot tightrope, suspended 173 feet in the air, from the U.S. side to the Canadian side directly over the Horseshoe Falls in Niagara Falls, Ontario. The famous funambulist is the first to achieve this feat. He holds six world records for other tightrope walking stunts, including the longest and highest tightrope crossing by bicycle.
