that walking through glass trick is the shittest magic trick I've ever seen!!! the guard blocks the view of the door for a good 3 or 4 seconds, it's not even clever or quick how they've done it! Forward this to 1:45, the guard on the right is the worst actor in the world, why would he be looking up at the ceiling like that???
