Dice Through Mirror
Only ONE dice is used! It can even be borrowed!
The performer shows a wallet with a small square in the middle. A mirror attached to a ribbon is passed around for inspection, then inserted into the wallet. A spectator may hold onto the ribbon to make sure the mirror doesn't move. A die is also inspected. The die is placed in the square in the wallet.
Then, bit by bit, it very slowly sinks until it completely penetrates the mirror and drops to the floor.
The die and mirror are once more passed around for examination. Quality constructed to last and a great penetration illusion of a solid object
