A history-making event came to a successful conclusion Friday night as daredevil Nik Wallenda stepped off his tightrope onto Canadian soil, ending a tense 25-minute journey across Niagara Falls. Wallenda's journey across the 457-meter wire, which was just 5-inches in diameter, began at 10:16 p.m. ET on the United States side of the falls. It ended in Niagara Falls, Ontario, at 10:41 p.m. where Wallenda was greeted by his wife, three kids and an estimated 120,000 cheering spectators.

Below is the Sport Science of how he did it.
