How does the pepper's ghost illusion work?

Answer:
It works like this: You take a bottle of Pepper and a white cloth. You rub the insides of the (full) bottle until the white cloth is totally and completely coloured by the pepper. You then shine light through the cloth onto a beaker full of water.
