Wallenda said Monday at a New York City news conference that the Orlando Eye will be moving when he attempts his feat April 29. The Orlando Eye, part of a new entertainment complex, will offer views of central Florida from inside 30 enclosed, air-conditioned glass capsules when it opens to the public on May 4.

Tough challenge: The 36-year-old daredevil will walk atop the Orlando Eye as it turns on April 29 . The Orlando Eye team issued a statement saying it's excited to have Wallenda attempt the 'amazing stunt.' No distance for the performance has been set yet, but Wallenda, 36, said he was not likely to walk the entire 20 minutes or so that it takes the wheel to go a full circle. Wallenda previously walked atop a Ferris wheel in Santa Cruz, California, but he said the size of the much larger Orlando wheel and the fact that he will not use a pole sets this stunt apart. The seventh-generation member of the 'Flying Wallenda' family of acrobats has walked across the Grand Canyon and Niagara Falls. In November, he walked twice between two Chicago skyscrapers without a net or harness, doing the second walk blindfolded. Wallenda is the great-grandson of Karl Wallenda, who fell to his death in Puerto Rico at 73.
