Magician David Blaine appears on today's Oprah to attempt to break the Guinness World Record for holding one's breath while immersed in a water-filled tank.

The previous record was 16 minutes and 32 seconds. In 2006, Blaine's attempt at breaking the record was cut short when he went into convulsions and had to be pulled from the tank by medical personnel.

Spoiler alert: FoxNews.com is reporting that Blaine broke the record by holding his breath for 17 minutes and 4 seconds while underwater. - J.R. Whalen
