The Baghdad Battery

Discovered near Baghdad in 1938, a small, unassuming jar turned out to be an ancient battery. About 2,200 years old, the mechanism consists of a copper sheet held in place by an asphalt plug, with a narrow iron rod hanging down the center. Fill the jar halfway with vinegar or another acidic liquid and you get 1.5 volts. It is speculated that the battery may have been used for electroplating or served some sort of medical purpose.
