Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte.

I'm gonna guess the reaction is between the toothpaste (alkali??) and the potato (acid?). And the salt is a catalyst and also acts as an electrolyte.
Or it could be the reaction is between the potato and the salt - and the toothpaste is more of a capacitor to hold a bit of charge.
Now you have fire what you really need is a recipe for a salty minty-fresh potato meal... Mmmmm.
