NEW YORK (AFP) - Magician David Blaine completed his 60-hour upside down ordeal in New York on Wednesday, but some complained the illusionist's bid to emulate Batman was itself an illusion. Blaine, 35, ended his latest stunt by appearing to vanish from the structure where he had spent nearly three days " most of it hanging head down. Having completed the promised 60-hour period, he leapt from the metal frame holding his cable, then was hoisted back into the dark sky, giving the impression of disappearing. Some in the crowd attending the finish grumbled that Blaine exaggerated his feat, because he wasn't actually inverted the whole time. During much of the period he stopped for regular breaks on his feet " as often as once an hour " to drink liquids, urinate and undergo medical checks. "I am totally unimpressed," Joshua Yoselowitz, a 31-year-old banker, told AFP. "I'd rather be at home. If his name hadn't been David Blaine I would never have come." Undoubtedly the hanging stunt was a physical and mental test. The daredevil magician has previously spent 72 hours encased in ice, 44 days in a plexiglass box, a week under water, and been buried alive. But he told AFP at the start of the challenge Monday that he'd faced nothing harder. Blaine apparently did not sleep for two nights and he spent nearly the whole period suspended the wrong way from a wire attached to a body harness and special boot clips. His doctors had described a very real danger of blindness and swelling of the brain.
