I'm going to try licking a 9 volt battery.

  Lol, be sure and try side, back, underside for the full experience. Sidebar: Having done this as a kid, I ended up being able to taste polarity. Hold one wire with finger, taste other and the polarity affects the "taste" sensation. And I realize I don't really have words to describe what it is like.
