Problema - Teak box

The magician displays an elegant wooden box containing six black dice arranged in order from 1 to 6, and closes it with a lid. He then hands a spectator a dice cup or any other small container (not included) with a die inside and asks them to shake it and flip it over the box, randomly selecting a number from the dice. Incredibly, when the magician removes the lid, all the dice now show exactly the same number as previously selected.

• The teak box measures 8 x 3 x 6 cm (3.14 x 1.18 x 2.36 inches).
• The presentation can be repeated a second time and at the end everything can be handed out for review.
