Dice Illusion (watch video).
The magician takes out a die without any color and a mirror. He lets the
audience examine both. Everything is normal. He explains how people make dice
and claims he can make a dice with a mirror.
When he places the die next
to the mirror, the dice itself doesn't show to have any color, but the dice in
the mirror does! The magician then makes the die full of color, but this time,
the die in the mirror doesn't have any color!
Finally, the magician
takes the dice from the mirror; he now has two dice!
Props include a
normal die, specially gimmicked die, small mirror, and instructions.
