A spectator is asked to drop 3 dice into a glass of water, raise the

glass over their head and count the total of the dice on the

bottom.

 

The spectator then sets the glass back down, the bartender dips

his finger in the water, rubs his finger on his forehead and after a

little concentrating, announces the total of the dice on the bottom

to the spectators amazement.

 

You will need a glass of water and 3 dice.

 

All you have to do is add up the total of the numbers on top of

the dice and subtract this total from 21. This will give you the

bottom total. Amazing.
