Magnesium, copper and flouridated/chloramine tap water battery

NOTE: This experiment has ended. Much smaller cells work just as well and longer if the magnesium is horizontally laid out near the water surface. Speculation is that the fluoride tends to concentrate near the water surface. This is a safe, easy to build, "flea power" battery cell/s. The voltage of each cell is ~ 1.35 volts; but the current is totally dependent on the size of the magnesium and copper electrodes used. Flouridated water occurs often naturally and
