Lemon Battery


Two weeks ago we put a zinc washer and a copper coin into 3 lemons. We joined them up: zinc to copper. We attached a LED bulb connecting the long leg of the LED with copper. The bulb did not light up. When we tried again and again. Eventually it worked and the light lit.
The zinc washer and the copper coin are electrodes. The juice is called electrolyte.
