The magician places a coin or ring inside a wooden box which is closed with the sliding lid. The magician may shake the box to make sure the coin or ring is inside which is confirmed by a rattle sound. The magician can give the box to the audience to shake the box but there is no sound and then they open the box but nothing is inside. The coin or ring has completely vanished from inside the box and will be produced from some other places.
