Magic Tricks Die Box

We are offering magic tricks die box,
the performer displays an empty double compartment box, with doors on front and top of box, and a solid die. The die is placed in one compartment and the doors are closed. The box is tilted, and the front door to that compartment is opened. The die is seen in that compartment. The door is closed and the audience is asked to remember where the die is. The box is tilted, and he front and top doors to that compartment are opened. The die is seen to have vanished. The audience is not impressed, because they have heard the die slide to the opposite compartment. They ask the magician to open the doors to the other compartment. The magician closes the door to the first compartment then tilts the box (the audience can hear the die sliding over), then opens the doors to the adjacent compartment to show that it is empty. This business of sliding die from one compartment to the other is repeated, till the audience is howling for all four doors to be opened. Finally, the magician opens all four doors, and proves the die has in fact vanished. The solid die is found in hat, or some other container.
