You know, two different metals (solder and copper, for example), under
certain circunstances (imersed in a acid solution), can do this.
Moisture from the air + poluition + acid atmospheres, etc...   It works
like a small lead-acid battery.

OT: Many years ago, I read somewhere (don´t remember where) about a guy
that had a bad "solder" (don´t know how to call it, it´s that thing the
dentists use to fill holes in our teeth...) that was detecting AM radio
stations. The rectified voltage was traveling from the tooth to the
inner ear by some nerves, and he thought he was getting crazy!

Nobody belives me when I tell...  :-(
