Mirrors but little smoke

Mirrors are tools that have been used throughout the ages....from the dawn of magic itself....a fundamental factor in illusion and its conception. There's the classic mirror in a box trick: since the mirror reflects the other half of the box it looks the same. Then there's the invisibility trick: with a mirror on stage or it can be used to make something that is there appear as if it isn't according to the physics laws of reflection. A mirror is placed diagonally in the box so it appears empty but in reality is not. Mirrors also reflect things so a mirror could be used to say make it appear as if one was levitating if you where to lie on top of a box and have a mirror on one side of the box. You would then only have to lift one arm a leg and it would appear as if you where lifting two. Thus is the art of illusion and the saying mirrors and smoke.
