The magician walks across a swimming pool.
The magician is wearing shoes that float.
Note: We have received several e-mails from concerned individuals pointing out that when Criss Angel walked on water he took his shoes off half way through the journey, apparently negating certain subtle details of the above explanation. But in reality, all this does is highlight what a wonderful magician Angel really is! In fact, Angel does not, at any time during the walk on water, remove his shoes. Instead, this "convincer" is accomplished by removing a pair of thin overshoes, revealing Angel's real shoes, which have been cleverly disguised as feet. Angel used these same "feet" shoes (with a different gimmick installed) to walk up the outside of a building.
