Given Sum - Dice magic Trick
EFFECT
You ask someone in the audience to move three dice (given normal, not poker), and place them on the stack (one above the other), you tell the public to be able to guess the sum of the faces that are not view of the dice, after concentrating for a few seconds you will be able to say that magic number.
MAGIC SECRET
The explanation to this trick is very simple, if you have never fixed, the opposite faces of a die always add up to 7, therefore, the opposite faces of three dice join 21. You see the number given above (in the picture is 1), therefore, the sum of the faces that are obscured by the dice and soil are 20 (21-1 = 20).
