Bellhop coin ladder

The magician borrows four coins which are placed in a glass, which in turn is placed in a hat which is put on the bellhop’s head. On the command of the magician a coin emerges from the bellhop’s mouth and zig-zags down the buttons, landing in a dish between the bellhop’s legs. The four coins appear one after another and the magician then shows that the glass in the hat is now empty. The coins are then returned to their owners. Complete with instructions.
