A Lemon as a battery

Here is a very easy project to light a small bulb using a lemon.
 .1 Lemon
 .Connecting wires
. Copper strip
 . Zinc Strip
1-Insert both Copper and Zinc Stirps to the lemon
2-Then the Copper acts as the positive pole and Zinc as the negative pole.
3-Add  the connecting wires to the strips and connect them to the bulb.
Here we are: The bulb is on!!!

How it works?
The lemon contains acid, so it reacts with both copper and zinc strip forming a low voltage!!!
