Really, you could put this clock anywhere you wanted, but the kitchen seemed the most appropriate to me! This Potato Power clock can use other fruits and vegetables too.
Finally, a chance to play with your food!
The Two Potato Clock allows you to generate enough electricity to run a digital clock – using potatoes! Just push the zinc and copper electrodes into the potatoes causing an oxidation/reduction reaction that is converted to low voltage.

I think it looks like a great little project!
