Vanishing-coin magic box

Drop a coin in, shake, open the lid, and it has gone

A magician's prop with a secret in the floor. Show the empty box, drop in a coin, close the lid and give it a shake so everyone hears it rattle. Then, holding it from underneath, tilt it slightly towards you: the coin slides through a hidden slot along the floor edge straight into your palm. Shake again (silence), lift the lid, and the box is empty. Produce the coin from a spectator's ear for the finish.
