The story of "bubbler"

and they provide a linguistic map of the use of "bubbler"

Obviously, this is an excellent example of what I mentioned above as 'naming items by the most common local commercial product name.', as in Jello, Listo, etc.
I can see why this would happen, but it frustrates me when folks stubbornly cling to their local nomenclature even after moving from an area and realizing that it was NOT a generic name. (not you, Carol...I realize you were only noting it.)
   Ah well, I am a philosopher...not a psychologist. I keep expecting reason from human beings.
