Nik Wallenda has performed his first practice walk on the tightrope he'll use to walk above Niagara Falls next month.
The Buffalo News reports an estimated 200 spectators came out to watch Wallenda as he slowly crossed the five-centimetre steel cable strung between two cranes in front of the Seneca Niagara Casino.
Wallenda said he stopped after walking about a third of the wire's length because he could feel the cable moving beneath his feet.
He later placed a short weighted pole on the cable to the prevent movement.
Wallenda is a seventh-generation member of the famous daredevil family the Great Wallendas, also known as the Flying Wallendas. His high-wire walk is set for June 15.
Wallenda would be the first to walk above the falls themselves.
