Pepper's-ghost haunted box

Make a ghost appear and vanish inside a box using a hidden sheet of acrylic

A Victorian stage trick in a box. Look through the window and you see a dark little room. Switch on the tealight in the hidden side chamber and a ghost (any small figure or a cut-out picture you put beside the light) appears floating in the middle of the room, then fades away when you switch it off. A clear sheet standing diagonally across the box reflects the lit side chamber over the room behind it: the same trick, called Pepper's ghost, that makes holograms on stage and ghosts in theme parks.
