Jewelry Box Prediction

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

This effect is a gem!

• The box measures 12 x 7 x 9 cm.
