Chris Angel did something similar where he walked through a pane of glass, leaving the glass intact.
Highly bizarre and much better than anying David Blaine does..
MIND FREAK!!!!!!!!!!!!!!!!!!!
Chris Angel is a hack. The "walk through a pane of glass" trick is the oldest in the book. Hint: THE GLASS MOVES. It slides up from the bottom (in the instance where I saw Angel perform it). Big ass hole covered by the newspaper. If you drew a smiley face on the window with a Sharpie before the trick, you'd see it magically move up 2 feet, then magically go back down after Angel was through.
I saw one of Angel's recent shows, and the whole thing was schtick. I could explain every trick. Just really simple-minded stuff.
Blaine's so far beyond Angel it's not funny. His hands are just stunningly fast. He has his own share of gimmicks, but his street magic stuff awes me.
BTW... that Japanese thing... I don't have a clue either. On that last one I'm tempted to claim the whole room was in on it, and with all the camera cuts they just replaced the glass.
