David Blaine Held His Breath For More Than 17 Minutes:

CHICAGO (AP) — David Blaine took on a Zen-like appearance in the water tank as the minutes ticked by during his attempt to set a new breath-holding record. Oprah Winfrey, however, was anything but calm.

She fidgeted in her chair, pursed her lips, placed her head in her hands, and kept seeking reassurance from the doctor at her side about the 35-year-old magician's persistently high heart rate.

"I'll be glad when it's over. I don't like suspense," she told the audience during a commercial break.

Soon enough, Winfrey — and Blaine — could breathe a lot easier.

Submerged in a water-filled sphere on the stage of "The Oprah Winfrey Show" during a live broadcast, Blaine held his breath for 17 minutes and 4 seconds. That bested the previous record of 16 minutes and 32 seconds, set Feb. 10 by Switzerland's Peter Colat, according to Guinness World Records.

Quite the feat. And for his next trick? 12 days awake...
