Why do you want people to guess what the hell you are talking about?

Do you really think that everyone known what you mean when you talk about a "beer bottle capacitor"?

If it is a capacitor that uses water as it's dielectric, then it would not be unreasonable to put some oil on top to prevent the water from evaporating.

Any oil will work just a motor oil would be best. Cooking oil can mold its just to close the bottle off and keep the water in it.
