Battery Out of Coins and Foil
Ran out of battery? You can now make your own battery with some of the objects you'll find lying around your house!
Materials Needed:
You can also use a Voltmeter to check if it has already produced your desire voltage.
Cut Coin-sized Circles From the Aluminum Foil and Cardboard.
Dip the Circles Made From Cardboard in the Mixture of Vinegar and Salt.
Put Them Together. First, the Foil Followed by the Cardboard.
Measure.
Just continue adding coins, foil and cardboard until it reaches your desired voltage. Well, what I want was 9V but I only got 4.33V so I added more 'till it reached 9V.
Put the Wires.
Tape Them Together to Prevent Them From Being Separated.
That's it! Now you have your own homemade battery! :)
