David Blaine has revealed he would love his next challenge to be placed in a life-sized bottle in the middle of the ocean.
David Blaine wants to be set adrift into the ocean inside a glass bottle.
The illusionist - famed for his endurance stunts, including holding his breath for over 17 minutes and spending 44 days without food suspended in a Perspex box in London - is currently working on turning a dream he had into a reality.
He said: "What am I working on next? It started because I had a dream one night that I was in a life-size bottle in the middle of the ocean. That's where it started, and now I'm trying to work out how to make that into a physical reality - into a real physical feat."
The 37-year-old star is also "obsessed" with breaking the record for sleep-deprivation but doesn't think it is possible as he suffers from extreme hallucinations whenever he attempts the challenge.
He explained to Interview magazine: "The one I've been obsessed with, that I don't know how it could be done, is the sleep-deprivation record. "It's 11-and-a-half days. I was thinking I'd try to go one million seconds under test conditions, which is 11.57 days or something close to that.
"But I started experimenting, and for some reason it's the hardest. I think you can build up a tolerance to sleep, but it's a really difficult process, because your body recovers during sleep.
"Your immune system builds itself when you're sleeping. So when I would do tests, I would be up for five to six days, and of course I'm hallucinating. But I also start getting these welts all over my body. I'm a super-hypochondriac. So when you're not sleeping, you start seeing things. And you think you're dying of this disease or that disease. It's really tricky on that end. But that's one that I've been really obsessed with for a long time because it's the scariest thing to me."
