Illusionist David Blaine became internationally famous when he started doing what he calls "endurance art"—death-defying stunts that test the limits of the human body. Over the years, he's been locked inside a clear coffin for a week, been encased in a block of ice and lived underwater for seven days. Then, in 2008, he decided to try to break the Guinness world record for holding breath underwater...live on The Oprah Show!
To accomplish this feat, David had to hold his breath for more than 16 1/2 minutes! Did he do it? Watch now!
Fun fact: Oprah said this was one of the only times Stedman asked to sit in the audience.
