Battery From Deodorant & Pennies (rechargeable)

Introduction: Battery From Deodorant & Pennies (rechargeable)

About: I am the been.

With 10 pennies & Speed Stick Deodorant I will show you how to make a battery to power an led or more depending on the amount of batteries used.  Entered into the pocket size contest PLEASE VOTE

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Small Amount of Deodorant

deodorant contains zinc that is why it can be used , take a small amount less than the size of a penny when flattened

Step 2: Vinegar/Lemon Juice/Salt Water/Baking Soda

Get any of the above and put it into a cup you can reach into. I used vinegar

Step 3: Cardboard/Paper Towel/Coffee Filter/Cotton T-shirt/

Take one of your pennies and trace it on the cardboard or whatever your using. Make 10 per 1volt
After you are done cutting them put them into the cup of vinegar for 5sec or so.
Take them out and pat them with a dry paper towel.
put it on your deodorant.

Step 4: Add a Penny

take a penny and put it on top

Step 5: Repeat

repeat the process until all 10 pennies are used



Step 6: Wrap in Tape Attach an Led

wrap it in tape if you want and hook up an led. The penny is positive and the deodorant is negative and you have power

Step 7: Expand

the zinc in the deodorant is suspended among other ingredients so it can be recharged via solar panel the possibilities are endless
hope you enjoyed

Step 8: Add on Solar Panel for LED

If you have an extra solar panel you can recharge the batteries and light an LED here is an example in my fish tank.
I am planning to add more blue LEDs soon.

    good idea, well instructed....
    But, once the vinegar dries up, dont you need to "refill". In your experience, how long it lasts without refilling (re-constructing)...?
    Any way, thanks for sharing..

    I have had my single battery powering an led for almost three months now with no change. I also made a 3.5 volt for my fish tank that I recharge with my solar panel.
    I don't think it's a matter of the vinegar being "wet" once it is saturated into the cardboard dry or not it will still be there so it should work indefinably.

    I remember making a project like this in grade school for a science fair.

    But some things I've learned over the years;

    any pennies made after 1982 are 92% zinc. But, they are coated in copper, so some sanding is required to sand them down. The vinegar, which has acid lets the metal flow as ions throughout the battery. The battery dies once all the potential energy is drained from it, not when the vinegar dries or anything like that. This is a chemical process. That being said, I'm NOT sure hooking up a solar panel can recharge these batteries. I'm looking into that as I type this...

    BUT one thing to be noted, I've seen other people build 10 cell batteries using the method I stated, and it lasted 2 1/2 weeks only powering an LED. That being said, there's no clue as to what happens when it's connected to a solar panel, as I haven't seen that applied to any of these batteries.

    It may be possible, but I have yet to find out. I'll update upon finding the result.
