Daredevil David Blaine performed an amazing balloon stunt last week in Arizona.
Blaine went nearly 7600 meters into the sky while hanging from a cluster of jumbo-sized balloons. He then parachuted safely back to earth.
YouTube streamed the vent and said that it set a new record as the most-watched YouTube Originals live event ever with over 770,000 viewers.
Blaine gradually dropped small weights to speed his ascent, donned a parachute mid-flight and strapped on an oxygen mask as he neared 7000m.
Blaine, 47, has a history of performing high-profile stunts. This includes locking himself in a fishbowl, trapping himself in a block of ice for two days in Times Square, and standing freely atop a thin, tall pillar for 35 hours in New York City.
