Chris Angel is MAD! Can you explain these three tricks?

Question

Levitation: http://www.youtube.com/watch?v=ovNwmhpbdlg (Chris Angel style, not David Blaine because that can be performed by anyone.)
Walking on water: http://www.youtube.com/watch?v=Nc9uAsdqMmc&mode=related&search=
Cutting a girl in half: http://www.youtube.com/watch?v=Z_gCDULzJNU

Answer 1

The woman in half is two people... One with no legs and a kid or a midget perhaps. That's why she is wearing a dress, not pants. Also picking someone else then say she's too short makes it appear more spontaneous. And some film editing puts it all together.

The water trick..
The secret will most likely points to illusion and camera video editing. The most convincing explaination to the trick is that Criss Angel was walking on some kind of floating device, or plexiglass, or transparent plastic bridge, or glass path, or vertical poles, which may have some gaps for swimmers to occasionally swin across it. Some also suggested that wires support was been used to hang him, which may be positioned under his arm, especially on the first 25 seconds or so. For all these tricks and optical illusion to happen, so all the ‘audiences’ and ’swimmers’ in the vidoe are actually the actors in the magic that were hired to add realistic and believable feel. The video may be edited by using CGI to hide the think platform in the water.
Some interesting points highlighted from the video on the magic are:

Criss Angel walked on his heels and his pant hung down and covered the heels.
His walking style looks unreal and unnatural on the front part of the magic.
The girl in red bikini swam underneath the water instead of crossing the path.
Water line on his pants changed, if you believe that the magic sequence was shot in multiple times.
A girl crossed between his legs after he took down his shoes, so the area may be without any platform.
In some shots, Criss Angel didn’t show weight hitting or weight shifting when stepped down, which made suspension possible.
His feet seemed like not stay in a position when stepping.

As for the levitation, there's a few possible devices he could be using. You can't trust 'street magicians' on TV... paid audiences (actors), video editing, etc.

Answer 2
