Step 1: Materials Needed:
You can also use a Voltmeter to check if it has already produced your desire voltage.
Step 2: Cut Coin-sized Circles From the Aluminum Foil and Cardboard.
Step 3: Dip the Circles Made From Cardboard in the Mixture of Vinegar and Salt.
Step 4: Put Them Together. First, the Foil Followed by the Cardboard.
Step 5: 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.
Step 6: Put the Wires.
Step 7: Tape Them Together to Prevent Them From Being Separated.
That's it! Now you have your own homemade battery! :)
