- TUTORIAL - EASY SCIENCE PROJECT - Power a clock with a potato! GUARANTEED A+ IF DONE RIGHT!

I Power a simple LED clock using potatoes, watch it is an instructional.

I understand that due to the shitty camera that was used and the fact that I was like 12 in this video, it may be difficult to hear all the essential information and follow along, so I found the original guide I used to make this project: http://www.kidzworld.com/artic....le/4726-how-potato-b

What You Need:
Two Potatoes (not sweet potatoes)
Two short pieces of heavy copper wire
Two common galvanized nails
Three alligator clip/wire units (alligator clips connected to each other with wire)
One simple low-voltage LED clock that functions from a 1- to 2-volt button-type battery

How the Potato Clock works

"A potato battery is an electrochemical battery, otherwise known as an electrochemical cell. An electrochemical cell is a cell in which chemical energy is converted to electric energy by a spontaneous electron transfer. In the case of the potato, the zinc in the nail reacts with the copper wire. The potato acts as a sort of buffer between the zinc ions and the copper ions. The zinc and copper ions would still react if they touched within the potato but they would only generate heat. Since the potato keeps them apart, the electron transfer has to take place over the copper wires of the circuit, which channels the energy into the clock. Presto! You have potato power."
