Problema, Original German Version by Trick Supply

Truly a warehouse find. This is the original version from Germany by Magische Schatztruhe.

A small box contains six dice. They are seen to be turned up with the numbers from 1 thru 6. The box is closed, and a spectator is given a die to roll. Let's assume the number is 6, now when the box is opened all dice are facing up with the number 6.

A clever solution and very easy to do! Even beginners will love this.

Colors of dice cup and box varies!
