Homemade Battery cell
Take the wooden piece and with the help of screws attach the zinc plate on one side of it and copper
plate on the other. Also secure the ends of copper wire on each bolt, as shown in the figure. Make sure that these wire ends and the screw ends inside the wooden piece do not touch each other. Now put this wooden piece on the mouth of the jam bottle. Pour as much dilute sulphuric acid into it as to fully immerse the metal plates. The acid which you can get from any chemist, should be handled carefully as it can burn your skin.

Well, your wet battery cell is ready. Now it's a different matter that you can't power a bulb or so with it. But if you put the naked ends of the wires on your tongue you can feel the tingling sensation of a current.Which proves that this cell is producing electricity.
