ABSTRACT OF THE DISCLOSURE This new apparatus for making foam from water, air and surfactant produces very small bubble foam by discharging the ingredients for the foam through passages that cause the stream of ingredients to be alternately expanded and contracted as by travel along tortuous passages to generate the foam. The foam may be delivered to pipes of relatively large diameter to a place of use, particularly for dusk suppression. A more uniform flow of foam is obtained as compared with foamers of the prior art where the foam sometimes broke up into alter- nating slugs of foam and air when discharged from pipes of large enough diameter to cause the foam to travel at low velocity.
