Save electric power using a lemon

We are going to use: well cleaned and wiped lemon, two pieces of copper wire 0.2 – 0.5 mm thick and 10 cm long, steel paper-fastener and a small lamp from the pocket flashlight on 3.5 volt.

Clean opposite ends of both wires on 2-3 cm long. Stick the paper-fastener into the lemon and connect (tie) it to the one side of wire. 1.5 -2 cm away from the paper-fastener stick another wire. You can use a needle first to make a hole in the lemon, then it’s going to be easier to stick wire into it.

Now if you connect two ends of wires to the lamp it’s going to light! If it’s not, take a few lemons and connect it like it shows on the picture.
