Lemon Battery

For the first project, we made a battery using a lemon. The lemon was first pierced with a piece of copper wire and then another piece of galvanized(zinc coated) metal. I used a screw for the latter. The two metals acted as the electrodes(Copper as Anode and zinc as Cathode) and the citric acid as the electrolyte for the conduction of electricity. Voltage measurement using a multimeter showed that the lemon battery had an output of approx. 0.6V. I did this as a part of my 8th grade project so I remembered bits of what had to be done, but doing it again did not diminish it's awesomeness.
