Potato Powered LED!

About: My name is Babak Eshghi and I am currently operating ScienceKitShop.com, a retail and wholesale distributor of science education products, based in Clifton, NJ.

LEDs require more than 2 volts to light up.

Each Zinc-Copper Potato produces 1 volt. In this particular setup, we've created 3 - 1 Volt batteries connected in a series so that they can light up an LED.

Please see photos for directions.

Also see "Metal Reactivity Series" table to learn more.
