Walking on Water
In this amazing illusion, Criss demonstrates his ability to walk on water.
Of course he didn't walk on water, so what did he walk on? We can only guess, but it was probably some sort of glass. The people in the pool were stooges, or at least most of them. Here is a video of Masked Magician (Val Valentino) performing his own version of this illusion and explaining it at the end. He used plexiglass.
