Making your own battery
Vikram
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. Voltage measurement using a multimeter showed that the lemon battery had an output of 0.6V.
