A wet cell battery is usually a container of liquid electrolyte with two metal rods in it. One rod is copper, and the other is made of zinc. The rods connect to a load (a load is something that converts electrical energy into another form of energy, ex: a light bulb) and power it. Wet cell batteries are often used in cars and other motor vehicles.
Believe it or not, you can make your own wet cell battery at home, without the use of harsh chemicals! You will need the following supplies:
- Various fruits and vegetables (If you want your battery to actually power something, you will need quite a few food items)
- Alligator clips (Useful for connecting your batteries together/to a load)
- Pennies or other copper object
- Galvanized screws/nails
- A voltmeter
- A small LED or other load (optional)
- A kitchen knife
- Paper towels
Step 1: Put it All Together
Take your knife and cut two small slits on the top of your produce, about 2-3 inches apart. Put the penny in one slit and the nail/screw in the other. You may want to keep paper towels nearby if you are using a juicy fruit.
