In one episode of the 1960s television sitcom, Gilligan's Island, the famous professor constructed voltaic cells to use as substitues for their radio's dead batteries. A single D-cell has an emf of 1.5 V. Which scraps of metal from their damaged boat, the Minnow, could best be used to create a 1.5 V voltaic cell? Assume that coconuts make great beakers and that seawater is a terrific electrolyte.
