Step 2: Soak the Cardboard
Once the cardboard inserts are cut out, place them in a mixture of salt and vinegar. I used a 1/4 cup of white distilled vinegar and 4 tablespoons of salt. Mix it thoroughly until all of the salt is dissolved. Allow them to soak until they are completely saturated.
Step 3: Sand the Pennies
It's necessary to remove the thin copper from one side of 5 of the pennies. I used a Dremel, but any kind of sandpaper will work for this step. Make sure that you leave one of the pennies with copper on both sides.
Step 4: Stack the Battery
Now start stacking the battery. Place a penny sanded side up. Place a soaked cardboard insert. Repeat. End with the unsanded penny on the top.
Step 5: Cover the Battery
I used 3/4" heat shrink tubing for this step. Electrical tape would work as well. Just make sure that the cardboard parts only touch the pennies that they are closest to.
Step 6: Wait for Charge
It will take a little bit of time to allow the battery to charge. The first picture was right after the battery was made. The second picture was 5 minutes later. Within 15 minutes, the battery was producing 3.2 volts.
Step 7: More Information
I decided that I wanted to measure how long the battery would hold a charge. I made a quick program and hooked it up to an Arduino.
How to make a penny with vinegar and salt?

How Does the Coin Battery Work?
They are both conductors of electricity. When two different metals are connected by an electrolyte (which is the vinegar and salt solution), a chemical reaction occurs at the surface of the metals. These metals are the electrodes. When these electrodes are connected by a wire, they create an electrical current.
How to make a penny out of paper towels?
In a small bowl, mix together the salt in the vinegar until the salt is dissolved. Cut the paper towel (or coffee filters) into small squares. You will want them smaller than the coins so they are not overlapping. Dip the squares into the vinegar and salt mixture and layer the coins in a pattern: penny, paper, nickel.
How much power does a coin battery make?

How to change voltage on a penny?
Attach the voltmeter clips to the nail and penny. Using the end clips of the voltmeter, attach one clip to the nail and the other clip to the penny. You should see a small increase in voltage on the voltmeter. If the voltmeter is reading a negative value, simply switch the clips on the nail and penny and it should change to a positive voltage.
How to put a copper penny in a lemon?
Cut a small slit through the rind in the middle of the lemon. The slit needs to be large enough to insert the copper penny about halfway into the lemon. Adult supervision is recommended for this step. You want the penny to stay firmly in place so don’t cut the slit too large.
How to make a battery from a lemon?
To create a battery from a lemon, roll the lemon on a hard surface to get the juices flowing. Next, cut a small slit through the rind in the middle that's big enough to insert a copper penny about halfway. Insert the penny, then insert a nail about 2 centimeters away.
How to clean a penny?
Rinse the penny with a light detergent to ensure you are working with a clean surface . Any lemon will do, but a lemon with a thinner rind will make a better battery. If you have one, a strip of copper will work better than just a penny. Galvanized nails have a zinc coating that is important to this experiment.
What happens if you touch a lemon battery?
Be careful not to have the nail and penny touch within each lemon. If they touch, the battery will short circuit and you won’t get any voltage.
What is the copper in a penny?
Any U.S. penny before 1982 is about 95% copper. For zinc, any US penny from 1982 on to most recent pennies are zinc based. You must sand down the newer pennies to get to the zinc core. Look on eBay and such places for the coins.
How many volts does a penny battery generate?
With a voltmeter, you can see that each cell can generate over 0.6 volts. The penny battery you created for this Snack has four cells. A stack of three cells should generate enough voltage to light a red LED, which usually require around 1.7 volts.
How to test battery life on a penny?
Test your battery by connecting your LED. Touch the longer lead to the intact penny on the top and the shorter lead to the bottom of the stack. Make sure that the leads don't touch any other layer. Did the LED turn on? If not, make sure the LED leads are oriented correctly and use a paper towel to wipe off any excess water from the penny-matboard stack.
How to stack a penny with matboard?
Take one of your sanded pennies with the zinc side facing up (copper side down), and place a damp piece of matboard on it. Then stack another sanded penny (again, zinc side facing up) on top of this. Take your next piece of matboard and place it on top, and continue stacking pennies and matboard on top of each other to make a neat pile. Finally, place the unsanded penny at the very top.
How to sand a penny?
Use sandpaper to remove the copper from ONE side of each of four pennies. Leave the fifth penny intact. Sand until you see zinc (shiny silver color) covering the entire face of the coin. This takes some time and effort, so be patient. Try placing the sandpaper on a hard surface and moving the penny instead of the sandpaper. The "tails" side may be easier to sand because the Lincoln Memorial (or Union Shield) doesn't protrude as far as Lincoln's head. When you're done, the sanded coins should have a bronze-colored copper side and a silver-colored zinc side.
What is a voltaic pile?
This is also called a voltaic pile, which is named after Alessandro Volta, who created the first battery in 1800 by alternating zinc and copper electrodes with sulfuric acid between them. In Volta’s battery and your penny battery, an oxidation reaction occurs at the zinc electrode that releases electrons and a reduction reaction occurs at the copper electrode that uses them.
How to make matboard with salt and vinegar?
Make a saturated salt solution by adding salt to water and stirring until it doesn't dissolve anymore. Add a splash of vinegar to this solution. Cut your matboard into four 1/2-inch squares, each about the size of a penny. Soak the pieces in the salt-and-vinegar solution.
What is the electrolyte used in penny?
The matboard soaked in salty vinegar water serves as the electrolyte between the two terminals.
Step 2: Cardboard Soakin'
In this step, you will need three cardboard circles (the size of a penny) and place them in the Ziploc Bag. Add some water and a good amount of salt to the bag. Let the cardboard soak for a few minutes while you continue on to other steps until these pieces are needed. (This step may take some trial and error)
Step 3: Set Up
In this step, you will need those two wires (preferably different colors) and the object needing battery (calculator). Attach the two wires to the positive and negative side. For me, I connected the white to the positive side and black to the negative side.
Step 4: Taping
You will need to add a piece of tape to the end of the positive side and place the penny on top, making sure the wire and penny are touching.
Step 5: Adding All of the Needed Items
Now stack the little items in the following order until you have no more (I had to do this three times but you may need more or less Volts depending on what you chose to power):
Step 6: The Product

Who invented the electric battery?
You might think that batteries are a modern invention, but batteries were one of the first ways of making electricity. Alessandro Volta discovered the first electric battery in 1800. He made a giant stack of alternating layers of zinc, blotting paper soaked in salt water, and silver.
How does a voltaic pile make electricity?
How does a voltaic pile make electricity? The key to electricity is the movement of particles carrying electric charge . In a voltaic pile, these particles move from one metal to the other through a solution called the electrolyte. An electrolyte is a liquid that contains particles carrying charge. Dissolved salt is an example of a good electrolyte. The charged particles in the electrolyte react with the metals, causing an electrochemical reaction, a special kind of chemical reaction that makes electrons. As electrons are particles that carry electric charge, making these electrons all move in the same direction will create a electric current or electricity. You can read more about the basics of electricity in the Science Buddies Electricity, Magnetism, & Electromagnetism Tutorial.
How is a voltaic pile made?
A voltaic pile is created by inserting a copper pipe through the middle of a stack of rings. Each ring has 3 layers: a base zinc plate, a piece of blotting paper, and a top silver plate. The blotting papers were soaked in salt water and the electrons from the salt were able to move across the metals into the copper pipe to create electricity.
What are the two types of metals in a voltaic pile called?
The two types of metals in a voltaic pile are called electrodes . As the types of metal are different, one metal will like to give off free electrons, the other will be more eager to receive electrons. This creates an electrical potential difference, also called voltage between the two types of metals.
Where to put aluminum strip on multimeter?
