Here’s What You Need
zinc nail or screw or galvanized nail
ohm meter (a device to measure electricity)
Make a Fruit Battery
1)Set the fruit on a table and gently roll it around to soften it up. You want the juice to be flowing inside the fruit without breaking its skin. Alternatively, you can squeeze the fruit with your hands.
2)Insert the zinc and copper nails into the fruit. You don’t want them to be touching each other. Avoid puncturing through the end of the fruit.
3)Take the Ohm meter and connect the positive connector to the copper nail (the positive connector is usually red, the negative black) and likewise with the negative connector to the zinc nail.
4)When you connect the second nail, the dial on the ohm meter will move!
