Lemon/fruit battery

Question	Answer
Turn over for the equipment list... Image: Jfq0 K56 X (image/jpeg)	citrus fruit (e.g., lemon, lime, orange, grapefruit) copper nail, screw or wire (about 2" or 5 cm long) zinc nail or screw or galvanized nail (about 2" or 5 cm long) holiday light with 2" or 5 cm leads (enough wire to connect it to the nails)
Step 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.
Step 2	Insert the zinc and copper nails into the fruit so that they are about 2" or 5 cm apart. You don't want them to be touching each other. Avoid puncturing through the end of the fruit.
Step 3	Remove enough insulation from the leads of the light (about 1") so that you can wrap one lead around the zinc nail and one lead around the copper nail. If you like, you can use electrical tape or alligator clips to keep the wire from falling off the nails.
Step 4	When you connect the second nail, the light should turn on!
