Note the labels − and + marked on the potato indicating that the copper electrode is the positive terminal of the battery. A short screw and nut connect the electrodes to the copper wires that have black and red insulating plastic coatings. |alt=Photograph of a potato. A copper wire is stuck into the potato, and an insulated lead wire is connected to the top of it using a nut and screw. A galvanized machine screw is also stuck into the potato. There is a nut that is next to the screw head; the second lead wire is squashed between the head and the nut. A "+" symbol is marked on the potato's skin near the copper wire that is stuck into it.]]
