It really works!

Here’s How to Make a Penny Battery:

Okay, so I’ve looked around for an idea for an instructable. And I found one that I want to do my own rendition of, the penny battery. So this idea is not completely original, I’m not claiming it as mine. I’m just using the materials and methods that I think will be the most effective. My hope is to power and LED light or a small fan if possible. But if I make the led die, then I have sufficiently surpassed my expectations. Let’s get started.
Penny Battery Tutorial and Instructions

Step 1: Materials

These are all the things you will need. I will include my list as well as some substitutes that I’ve seen.

5-7 Pennies
Paper towels (I used shop towels, but I’ve seen everything from cardboard to cloth)
Lemon juice (salt or vinegar works too)
Sand paper
Tape-recommended
LED

Tutorial & Instructions

 

Step 2: Sand pennies

Take the sand paper and sand one side of each penny down til the copper is off that side and the zinc core is showing. Best method is to use your finger to move the penny on the sandpaper as far as I know. (Technically defacing currency is a federal offense or something like that, but I’m sure you won’t get arrested over 6 cents. Besides, it’s recycling so shut up.)

Step 3: Make lemon juice solution

So, from what I can tell others have used salt water, vinegar water, well I’m gunna use lemon water. Lemons are more acidic than vinegar so I’m hoping it’ll work better. Feel free to correct me if I’m wrong. But I will use 3/4 lemon juice, and maybe put some salt in for good measure.
