PCT No. PCT/AU91/00377 Sec. 371 Date Apr. 27, 1992 Sec. 102(e) Date Apr. 27, 1992 PCT Filed Aug. 22, 1991 PCT Pub. No. WO92/06340 PCT Pub. Date Apr. 16, 1992.A snow making apparatus comprising a housing defining a bore (14) which is open at least at one end and having first and second annular chambers (38, 32) which extend circumferentially of the bore. The first and second chambers (38, 32) are respectively connectable to a source of pressurized water and of pressurized air. A circumferential array of outlets (42) from the first chamber (38) is operable with pressurized water supplied by chamber (38) to direct water jets along and towards the axis of the bore. A circumferential array of passages (36) provides communication between the second chamber (32) and the bore (14), each passage (36) opening towards or beyond the one end of the bore (14). The passages (36) discharge pressurized air supplied to the second chamber (32) as a plurality of air jets directed towards or beyond the one end of the bore (14), to generate a flow of air which passes beyond the one end of the bore (14). In use, the water jets impinge on the air jets to thereby generate snow particles which are carried axially beyond the one end of the bore (14).
