To be honest, I was worried when Cameron came asking for a conductor, preferably copper wire, because he wanted to play with electricity. After I was sure he was neither going to stick anything into an outlet, nor build something potentially explosive, I supplied him with copper wire. With some salt water and some aluminum, he managed to generate 1.47 volts. I asked him where he got the idea and what directions he was following, and he said, with exasperation, "This is just stuff I know!" (Geesh, Mom!)
