There should have been a final step in that article, the one where you balance a herd of brighly colored elephants on the tip of a pin pushed through the battery, turn around anti-clockwise slowly by hopping on your left foot and chanting anti-martian mantras while doing so. Observers will immediately recognize you as a gold hunter when they see you doing that.
If nothing else, it serves to show that the internet is NOT a reliable source of information sometimes.
