Hi there. In this piece of content I’m going to be telling you how to make your own homemade battery .

What You Will Need:

• Some metal kitchen foil.
• Ten two pence pieces.
• Blotting paper.
• Two pieces of copper wire (taken from any electrical wire or flex).
• Malt vinegar.
• Salt.
• Masking tape.
• A bowl.
• And an LED (light emitting diode) you can get these from most hardware shops.

Method:

1. Firstly cut the blotting paper and the foil into circles so that they can be stacked on top of eachother with the two-pence pieces. But make sure you cut the blotting paper a bit bigger than the circles of foil and the two-pence pieces so that the metals don’t touch.
2. Next mix some vinegar and a little bit of salt together in the bowl. Common salt is sodium chloride, a combination of a positive and negative ion (Na+ and Cl-) These will separate in the vinegar to increase it’s effectiiveness as a battery.
3. Soak your circles of blotting paper in the now ion rich vinegar.
4. Using some masking tape, attach the end of one of the pieces of copper wire to the underside of one of the discs of foil you cut out earlier. This will act as the negative part of the battery. Now stack the rest of the pieces ontop of that foil disk in this sequence: Foil, paper, coin, foil, paper, coin. Each combination is it’s own tiny battery but you’ll still need quiute a fw to light even an LED (they don’t use much electricity).
5. When you have a stack, you can attach the other copper wire to the top coin and attach the two wires to the led and watch it light up. If you make the stack even bigger you can eventually power a small torch or even a light bulb with a big enough stack.
