As you attach each alligator clip to an electrode, you can simultaneously clip the electrode to the top of the cup to hold it in place, as shown in the photo below. Connect the cells in series by clipping alligator-clip leads from the copper electrode of one cup to the aluminum electrode of the next cup, and so on, until all five cells are connected (see photo above). Each cup and its electrodes make up one saltwater cell.The broomlike end of the copper electrode should be in the solution. Then put one aluminum electrode and one copper electrode in each cup. Fill each plastic cup about three-quarters full of the electrolyte solution.This is the electrolyte solution-a liquid that can conduct electricity. Fold each piece in half, and then in half again, parallel to the first fold, so that the foil square ends up four layers thick, with final dimensions approximately 1 x 4 inches (2.5 x 10 cm). Cut five pieces of aluminum foil, each about 4 x 4 inches (10 x 10 cm) square. ![]() Then separate the strands of each 2-inch (5 cm) end so the loose strands look something like a broom (see photo below). Twist the strands at the 1-inch (2.5 cm) end of each piece tightly together. This will leave a 1-inch (2.5 cm) sleeve of insulation holding the bundle of fine wires together. Strip 2 inches (5 cm) of insulation off one end of each of the five pieces, and then strip 1 inch (2.5 cm) of insulation off the other end of each piece. ![]()
