Homemade Battery

A battery is a cell that is able to create electrical energy. How Stuff Works says, "A battery is essentially a can full of chemicals that produce electrons. 1" Store bought batteries create a chemical reaction inside the cell and electrons are created. Batteries have two terminals, negative and positive; negative is represented by (-) and positive is represented by (+). The electrons gather in the negative side of the battery. When you attach the battery to a circuit the electrons leave through the negative terminal, trying to get to the positive side.

Homemade batteries are possible, but normally do not create as much power as those commonly bought from the store. You can make homemade batteries out of lots of things. There are batteries that only require water, zinc, and copper, though they do not create much voltage. Creating more voltage then water batteries are food batteries. You can use citrus fruits, potatoes, and jalapeƱo peppers, among other things, with pennies and nails as batteries. I have also heard of such things as fermented grass batteries, and batteries using an ice cube tray with zinc, copper, what looked like dirt (it was called Earth, so I am assuming it is dirt), water, and magnets to connect the individual cubes of the ice tray. This seemed like the best method as it produced 12 volts. I chose not to create that one because I could not any information on it besides the YouTube video, and the video did not give enough information to complete an experiment. Instead I chose to work with a different battery.

The battery I am researching uses a soup can, salt, vinegar, warm water, metal wire with an alligator clip on one end, copper wire with an alligator clip on one end, and freshly squeezed lemon juice from two lemons. This battery supposedly generates three volts. This battery works because when you pour the warm water over the salt, it becomes a conductor. The vinegar and the lemon juice react and produce electrons. The electrons then leave via the wires and powers whatever is attached to it.

I said supposedly because there is some speculation that this battery could really generate three volts. In the comments on the YouTube page, people have said things like, it's faked with hidden batteries in a can. Others though say things like the science is true, so why wouldn't it work? I was surprised at the amount of voltage myself, after looking all over the internet most of the homemade liquid batteries didn't produce more than really one volt if not less. Even though I believe that the voltage looked particularly high, I don't think it was faked. It just seemed like if the person was to have faked it, why would he have gone through all the trouble of stopping and starting the camera without moving anything, but attaching the wires to store bought batteries instead, and then given it English subtitles, and put it up on YouTube if it was a lie? Or dumping and wasting the vinegar, water, lemon juice, and his time just to put batteries inside the can to get a fake reading? If this was indeed the truth then it would only take two cells of this battery to power the pudding mixer. That would be the most efficient battery to power it so far.
