Cut the potato in half. Wrap the end of a piece of wire around a galvanized nail and wrap the end of a second piece of wire around a penny. stick the copper side into one piece of potato and the nail into the other the zinc and copper electrodes should not touch each other. If a wire is connected between the Zinc nail and the copper penny electricity happens. Use a small bulb from a flashlight or LED light, it wont light a household bulb.

light bulb is a bit much to ask from a potato, try a little wrist watch or calculator.
zinc nail and a copper penny.
