Walking over Niagara Falls
Walking a tightrope over Niagara Falls is not an unusual boyhood dream when you're a 7th generation member of a famous circus family. Now that dream will come true for Nik Wallenda from the Flying Wallendas. It took law changes in two countires, but Nik Wallenda announced he has been given permission to walk on a 5cm cable strung 550 metres across the Niagra Falls. It hasn't been done in more than a century.
