1 Use sheet metal shears to chop the copper flashing during a sq. or rectangle to suit the dimensions of the electrical burner. make sure to use a chunk of copper flashing that's completely cleaned. you'll use sandpaper to completely take away any sign of corrosion before continuing.
2 Place the copper flashing on the electrical burner and switch the burner on. you may have to be compelled to "cook" the flashing for as long as half-hour or additional to develop a thick layer of black cupric oxide.
3 Allow the copper to chill slowly once the layer of cupric oxide has fashioned. it'll begin to flake off and will do therefore with some force because the oxide and therefore the copper cool at totally different rates.
4 Scrub the fully cooled copper below running water to get rid of any last remaining bits of oxide. Be gentle, as you are doing not wish to get rid of any of the red cuprous oxide that has been created in heating the flashing.
5 Cut another piece of copper to identical size. Attach each panels using the alligator clips to the within of the wide-mouth glass jar or plastic bottle with the highest discontinue. The panels mustn't bit and may bend to match the curves of the jar or bottle.
6 Connect the lead of the alligator clip that fastens the clean copper plate to the positive terminal of the meter. The negative terminal ought to then be connected to the cuprous oxide plate.
7 Make an answer of salt and water by dissolving the salt in hot faucet water. you must build enough answer to barely cowl rock bottom of the plates, leaving the clips high and dry.
8 Place your solar panel within the sun to check the gauge jump to mirror this your project has created.
