David Blaine intends to sleep with the fishes — but only for a week, and in full public view.
The 33-year-old magician will perform his latest stunt by living underwater for seven days and nights in a "human aquarium" in front of New York's Lincoln Center.
He will conclude by attempting to hold his breath underwater longer than the record of 8 minutes, 58 seconds.
The finale of his latest stunt will air live in a two-hour ABC special on May 8 (8 p.m. EDT).
Blaine's previous feats of endurance include balancing on a small platform for 35 hours and surviving inside a massive block of ice for 61 hours, both of which were performed in New York. In 2003, he fasted for 44 days in a suspended acrylic box over the Thames River in London.
The "human aquarium" in which Blaine will float is a specially built 8-foot acrylic sphere. He will receive liquid nutrition through a tube and the water will be kept at a balanced temperature to help keep his core temperature close to 98.6 degrees F.
Passers-by will be able to touch the aquarium, take pictures with Blaine and communicate with him. He will enter the sphere on May 1.
To prepare for the challenge, Blaine trained with U.S. Navy Seals and a world class free-diving team. An inside look at his training will be shown on the ABC special, which is titled, "David Blaine: Drowned Alive."
