Anyway, i was thinking that it would be nice to have it as a permanent display but there are two problems i forsee. One is over time mold, lime etc may build up and the second is evaporation of the water will mean constant refilling, especially in the dry winter months, and that will no doubt become a real nuisance pretty quickly.
So i was thinking it would be nice if i could use some clear odourless liquid that wouldn't have bacteria growing in it over time and didn't evaporate or evaporates very slowly, so replenishing it would be need infrequently.
Is there any such liquid?......any ideas?
