An Experiment to test which combinations of metals will produce the highest voltage in a variety of fruits to make a fruit battery Aim: To test which combinations of metals will produce the highest voltage in a fruit battery. Prediction: Safety: There is always a concern when using electricity and acids about the safety. Therefore I think it will be important to perhaps use gloves and goggles. Also, the experiment will be conducted whilst standing. Apparatus: * Two 8 cm long strips each of magnesium ribbon, zinc foil, lead foil, copper foil and iron foil. * A lemon, apple, potato and grapefruit, each with two holes cut in the top, 2 cm apart. * Crocodile clips and wires. * Digital voltmeter.
