Potato and fruit clocks abound as well as the old fashioned penny/nickel
cells. This is a classic classroom experiment that seems to appear
everywhere. Not finding one means that you haven't looked.
You'll note that any two metals can be used to make a battery. You
also don't have to spend $0 for a "kit". You can go down to your
local dollar store (if such exists in your area) and pick up some
LCD digital watches or car clocks. Just connect wires to the insides
of the watch where the battery goes.
