Push 2 metal plates (one copper one zinc) into each of them connect copper plate of a lemon to zinc plate of another lemon with wires.  3. Then connect wire from copper plate of first lemon to  long terminal(+) of LED (light emitting diode). 4. Also connect wire from zinc plate of last lemon to short terminal(-) of LED.
