yeah chris angel does some crazy shit, that water walking one was pretty cool but... i was looking really hard for some way he could be doing it... and take a close look at about 1:22 it looks like there is a slight discoloration between a little bit going diagnoly across on the left hand side of the frame and the rest of it... it could be a small pane of glass he's walking on as it's pulled across the water... i've seen it done before, it looks cool as fuck though.. i think thats how he did it.
