This is an old time apparatus used to produce a watch from inside a loaf of bread.  Mikame Craft has greatly improved it and added the very special feature.  SOUND!!

Borrow a spectator's watch and clearly place it in the box.
Close the lid and even open it again showing their watch is actually inside the box.
Now have some fun with them by shaking the box from side to side, it's still in there!
They hear the watch inside moving about, it's getting damaged for sure. Rattle - Rattle - Rattle
After a minute of shaking you open the box and their watch has VANISHED!
The box is shown empty!  The box rattles up to the second the watch vanishes! This feature is FANTASTIC!  Vanish any object that can fit inside the Bread & Watch Box.
