This instructable is a battery made of pennies, salt water, and nickels. It produces voltage much like a battery, but you use pennies and nickels instead. It is a fun project for those pennies and nickels you don't wish to use anymore. Most of us don't usually go to the coinstars, and our change just piles up, so make a battery out of them!

For about 1 volt, you will need:
(6)Pieces of paper towel cut to a size smaller than the nickel

Optional: Multimeter to measure the amount of voltage you have prodced.
