I'm attempting to make a Leyden jar by taking a plastic cup, covering the inside with aluminium foil, and then filling the cup with salt water. I have a spring sticking through the centre that conducts through the inner foil.
Judging from the Wikipedia article on Leyden jars I can use my hand instead of the outer foil, but how do I charge it? I clamped the positive terminal of a 9V to the spring and held the outside of the cup, but I can't tell that any charge is being stored in the foil. Should I hold the negative terminal too or what?
I can provide a picture on request.
