His London venture, however, is on hold for now because first he must survive the next week and the most daring stunt he has yet performed. On Wednesday Blaine will shin up a 100ft pole girded into position at a central New York location and stay perched there for 34 hours, subject to variables of sun, wind, rain, hunger, fatigue and his own thoughts. He will stand the entire time on a circular platform less than two feet in diameter, will go without food and drink, there will be no safety net and, at the end of his mission, he'll jump to the ground with just a mound of cardboard boxes to break his fall.
