Props: Two ordinary dice.
MAGIC:
Some of the best mind-reading demonstrations are those done with dice. They will be long remembered by spectators because of the obvious impossibility of the mentalist knowing anything or his being able to control the spectators' actions.
Here is a unique trick with dice, which you can perform anywhere. Show two ordinary dice to the audience, give them to a spectator and ask him/her to throw them on to the table. When he has done so, just glance at the dice and immediately announce the number of spots at the bottom of the dice. You will neither use any gimmicks nor touch the dice, but will always predict correctly.
SECRET:
Although all of us play different games with dice, many of us do not know a clever trick laying in the die. The total number of spots of two opposite sides is always seven. Ever since the die was invented, this formula is being followed all over the world. If there are three spots on the top, there will be four spots at the bottom. The combinations are: 1-6, 2-5 and 3-4. Once you know the secret you can immediately guess the number of spots at the bottom and astonish your friends.
