Jewelry Box Prediction

A wooden box is presented. The box is opened. It is seen that there are six compartments inside the box. In each compartment are six dice. On the dice are six different gemstones. The performer asks a member of the audience to choose any one die from these six dice. Suppose the spectator chooses the die with the ruby ​​gemstone on top. The die is removed from the compartment for a while. And then placed back in the same compartment. Now the performer pulls out a drawer from the front of the box. It is seen that in the drawer is a small ruby ​​gemstone. The spectator's selection is successfully predicted.

This effect is a gem!

• The box measures 12 x 7 x 9 cm.
