Can the human body be used as a battery?
My son and I are working on his science fair project which is to light a light bulb using a piece of copper pipe, a piece of galvanized pipe, and two wires with alligator clips to connect the light bulb. The theory is that holding the two pipes in ones hands, the body will create enough current to light the bulb. We have not had any success yet. Even wetting our hands had no noticeable affect. Any ideas? Is this a plausible theory?
