Jumbo Re-Appearing Die

The magician shows a small rectangular box containing three colored dice: red, yellow and blue. He takes the blue die out of the box and makes it vanish mysteriously.
He closes the box with its lid and shakes it letting everybody hear the noise of the 2 dice sliding freely inside the box, but suddenly the noise ceases. The magician reopens the box showing that the vanished die has magically reappeared in it next to the others!

• Very clever principle.
• The box is cm 11 x 4 (in. 4,3 x 1,6).
• Dice are cm 3,5 x 3,5 (1,4 square inches).
