A large potatoTwo penniesTwo zinc-plated nailsThree pieces of copper wireA very small light bulb or LED light
What you need to do:
Cut the potato in half, then cut a small slit into each half, large enough to slide a penny inside.Wrap some copper wire around each penny a few times. Use a different piece of wire for each penny.Stick the pennies in the slits you cut into the potato halves.Wrap some of the third copper wire around one of the zinc-plated nails and stick the nail into one of the potato halves.Take the wire connected to the penny in the half of potato with the nail and wrap some of it around the second nail. Stick that second nail into the other potato half.When you connect the two loose ends of the copper wires to the light bulb or LED it will light up [source: MathinScience].
