I suspended the copper plate inside the jar by wrapping the string around the plate and taping the other end of the string to the inside of the cap. I filled ⅓ of the jar with white vinegar. The approximate distance between the vinegar at the bottom and the suspended copperplate is about ½ inch. I place the jar by the window, where it gets the most sunlight
