Foaming fountain-nozzle for fountain systems, ponds or the like are, in a known manner, provided in a vertical arrangement in the water. It is to be possible to arrange the novel foaming fountain-nozzle in an appropriately adjustable position in the water. This is achieved by means of a ball joint (22) provided on the nozzle (Fig. 2). By virtue of the ball joint, the nozzle can be aligned in an infinitely variable manner in an oblique position in which an optimum water-air mixture is supplied to the pond or the like, with the water remaining calm. <IMAGE>
