Lemon Battery

πŸ‹This is an experiment to demonstrate how lemony chemical energy can be turned into electrical energy! 

πŸ‹This lemon battery is based on a similar concept as the very first battery, built by Alessandro Volta in 1799!

πŸ‹The battery works by moving electrons (little charged particles) from anode (negative: zinc metal, paper clip or a galvanised nail) to cathode (positive: copper metal, e.g. a penny coin) via the fruit.

πŸ‹If you set up your circuit correctly, you will be able to see it powering a small LED light.

πŸ‹Instead of lemons, you can also use other citruses (limes, oranges, grapefruits), or other acidic fruits. You can also use potatoes, they have a different chemical (phosphoric acid instead of citric acid) that allows them to power the battery. 

πŸ‹To make this battery work better, you can roll the fruit by such making it juicier inside or, if using a potato, part boil it.

πŸ‹You can also use acidic liquids, such as vinegar (acetic acid) instead of lemons.

πŸ‹The more lemons/fruit (AKA battery cells) you hook up, the more powerful this battery will be! 

Here is a photo from Hope set up by Alessia, that she then demonstrated on a call!

And here is a PDF of the experiment - please read it before doing the experiment!

So, which makes a better battery: πŸ₯”POTATOES or πŸ‹ LEMONS? Here is a video!
