A foam generating apparatus, comprising: means defining a swirl chamber; a partition defining an orifice in communication with said swirl chamber; means defining a venturi opening in communication with said orifice; and wherein said means defining a venturi opening is spaced from said partition so as to provide an area of substantially circumferential gaseous communication to liquid sprayed through said orifice and into said venturi opening; and wherein the travel distance for the sprayed liquid through said area of substantially circumferential gaseous communication and through said means defining a venturi opening is one-third (⅓) of an inch or less whereby liquid passes through said swirl chamber and said orifice to emerge therefrom as a fine mist spray and to entrain gas within said area of substantially circumferential gaseous communication both from venturi action and cyclonic action to emerge from said means defining a venturi opening as a foam within said less than one-third (⅓) inch distance of travel.
