Who knows.

Does that girl really cross in front of his path? I believe she is on his right side the entire time she appears to cross. i think the appearance of crossing is achieved by the heavy cameraman's movement. Notive that first he is walking backwards parellel to chris angel, and then, as she nears angel and hovers around him, he changes his direction and walks perpendicularly away from chirs angel. i believe this changes how we view her movements and that she is, as i said, always on his right side, appearing to look at his feet but in fact looking at empty water. also, in one of the hand held cam shots near the clip's end, there is an instant when both feet are in the air. so it was certainly not one shot. if not one shot, then all is suspect. dont we all know he is walking on something? plus, hes way too stupid to even be believable, and so he is a poor magician/illisionist. what a moron. irritating too watch. irritating to think this guy is wealthy or respected.

it was believable until the camera shot directly from underneath him. 

one must remember that criss wants us to figure out his tricks…her never claims to have an ounce of magical powers…plus he has at least one person in on the trick with him to dupe the rest of the crowd
