IMO, all those bottles, salt, tubs, etc are too much trouble. I'd suggest
making the type of cap that Bert H. suggested, using cheap 8mil (?)
poly, aluminum foil, and cheap mineral oil.
Those TV caps were low capacitance values, I think. New TVs have
almost nothing in them at all anymore to save costs. If they have
hamfests where you live, that's the best bet; you'll find something
