By embedding a coin-size battery into a hole in a polystyrene sheet, create a credit card-sized torch. The legs of a light emitting diode (LED) are placed either side of the battery and held in position with glued paper side coverings. When the sides of the torch are squeezed, the LED legs touch the battery and it lights up. No additional switch is needed.
(Battery included).
