On Sunday, Nov. 2, Nik Wallenda completed a tightrope walk over Chicago. That night he broke two world records and amazed the crowd.

Wallenda is 35 years old and began performing at age six. He is a part of the seventh generation of his daredevil family. His family calls themselves The Flying Wallendas and have their own circus act.

Thousands of people stood below to cheer him on. Before he started his walks he asked the crowd to stay calm so he could concentrate.

His walk on Sunday had two different parts. He started at the Marlina City’s West Tower at about 588 feet in the air and then crossed over the Chicago River to the Leo Burnett Building in less than seven minutes. After that he crossed to the East Tower, while blindfolded in one minute, 20 seconds.

He wore a microphone on his jacket as he accomplished the challenge. There was a live broadcast of his walk on the Discovery Channel for millions to watch, even for those not in Chicago.
