Graduate Student Dave Fleming demonstrates how electronic ink works using the egg tray and ping pong balls.

Electronic Ink

Electronic paper is made up of tiny balls that are white on one side and black on the other. The balls are sandwiched in between 2 sheets of rubbery plastic material. The balls can switch colors when they come close to a positive or negative charge. It is similar to when your hair is attracted to a balloon because of static cling.
