Electricity Out of Penny

Hey guys . Did you know that electricity could be made out of your spare change? Today I am going to show you how to make electricity out of Penny. It's completely green energy. Ok so lets begin........................

The things you will need for this project are,

1. A hand full of Coins

2. 100 grid sand paper

3. aluminium foil

4. Cardboard

5. Vinegar

Only 5 things. And these are available at any of your houses.I collected the coins from my neighbors.

First of all I took some penny newer than 1982 because they are 92% Zinc. I took some coins and sanded the tail side of the coin using 100 grid sand paper. While I was sanding my coins I found it very time consuming to sand the coin by holding it in one hand. So I used double-sided tape in a wooden base and then put the tail side of the coin facing up on the tape. As a result I could sand the coins with both my hands and it got easier than before. I stopped sanding when the tail sides of the coin was completely gray. As I sanded the coins on the double-sided tape, because of the friction the tape melted down and made my coins sticky. So I used adheser to remove the sticky layer of tape from the coin and it turned out very well.So my coins were very smooth an looked like new!

I took some coins and placed them on a cardboard .I cut the cardboard on the size of the coins. Then I kept the cardboard pieces in vinegar. For about 2 mins. Then I placed them on the aluminium foil in the pattern given in the picture. The battery is now done . The upper side of the coin is the positive side and the lower side is the negative side. I stacked 10 coins on the battery.With That power I could light two LEDs at once. However , I thought - For how long can the battery last? So I attached an LED with the battery and taped it well with electric tape. I light it up on 2/12/2014 and it's still on!!!! It's glowing continuously for 4 days. I don't know how much more will it last. However, share what you think and if you have a question please let me know in the comments .

-Thank You
