What’s the secret of the Criss Angel walks on water magic trick?

What’s the secret of the Criss Angel walks on water magic trick? How does he do it? The secret most likely points to illusion and camera video editing. The most convincing explanation to the trick is that Criss Angel was walking on some kind of floating device, or plexiglass, or perspex platform, or transparent plastic bridge, or glass path, or vertical poles, which may have had some gaps for swimmers to occasionally swim across it. Some also suggested that a wire support was been used to suspend him, which may have been positioned under his arm, especially for the first 25 seconds or so. For all these tricks and optical illusions to happen, perhaps all the ‘audience’ and ’swimmers’ in the video are actually actors that were in on the magic and were hired to add a realistic and believable feel to the trick. The video may be have been edited by using CGI to hide the thick platform in the water.
