2. Walk on water
Other than in Bible stories, it seems impossible to walk on water. Yet some magicians achieve this effortlessly and it’s still very impressive.
Except that these pros of illusion actually walk on plexiglass boxes installed just on the surface of the river, which is still quite difficult to set up. The boxes are transparent and you will notice that the water is always turbulent in this kind of illusion, it is to better hide the plexiglass.
