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

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.

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

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.
