I remember as a kid watching David Copperfield [1] making the Statue of Liberty disappear [2] and always wondering how he managed to do that. It was only years later when my friend Hoade told me how he did it [3] (okay okay, here's the Straight Dope [4]).
Well, that feeling of wonderment came back when I saw Criss Angel walking on water [5], across a crowded swiming pool at a Las Vegas casino. It's an amazing trick, however he managed to do it.
