Magic dice trick

The magician shows the audience a box containing bones in a random order. The magician casts a spell, closes the box and shakes it. After opening, all the dice lie in units facing up.

The secret of the trick:
Arrange all the dice so that the units are pressed against the side wall and are hidden from the eyes of the audience. In this case, the bones will be placed in a random order on top. Now close the lid and swing the box sharply, in a circular motion. All the dice inside will turn over and will be placed in units up.
