The method and the device for making fountains luminous are characterised in than one or more elongated light guide 6 of small diameter with respect to the cross-sectional area of the jet are introduced into the jet 3, 4, 5 to be illuminated, and one end of the guide or guides 6 is illuminated in order for the other end introduced into the jet and surrounded by the water of the jet to make the light enter the jet at an angle of incidence such that most of the radiation undergoes internal reflection on the surface of the jet which then behaves as an elongated light guide. <IMAGE>
