While it's not quite as exciting when you look at it (I originally thought he was going to be completely frozen, as in cryogenically preserved and then revived, ah well -- not that interesting

), it's still pretty amazing. "Magic" is all about misdirection and deception, but this stunt actually has a fair amount of amazing physical endurance involved.
Have you ever tried to stand for 2 1/2 days straight? Scarce few people could do that alone. How about while surrounded by ice and not being able to move at all?
I would like to see him in person.
