He he. I like that word “dohickies” (Doo Hick Ee’s) Anyways…. I’m doing the same thing as Caleb (Cae Lub) wrote. First I put stripped some copper wire and connected it to a 9V battery. I did that with both wires. Next, well actually first I mixed some baking soda in water. I put the wires in the water and it turned green and bubbled alot. The only wire that turned green was the wire on the positive side. Only two more posts……:)
