The word spa, taken from the name of the famous mineral springs in Spa, Belgium, has become a common noun denoting any place with a medicinal or mineral spring. Less well known is its Eastern New England sense, soda fountain, probably an allusion to the carbonated or mineral water that is a staple ingredient of many soda fountain concoctions.
