Lucky for us, we live in a universe that has valence electrons!

I'm guessing that my homemade batteries failed because I didn't have 
enough surface area on those plates. If you think of it that way -- 
with one of the plates being the source of the extra electrons -- then 
it becomes essential to have a lot of them that can move out, doesn't 
it?
