Apparatus for making snow using pressurized water and air wherein a housing is implanted into the earth at a selected location on a ski slope and connected to underground lines for supplying water and air thereto. An elongated extendable bichamberal spray head is slidingly mounted within the housing such that the introduction of pressurized air to the outer chamber of bichamberal spray head via the housing causes the spray head to rise to a predetermined elevation. Introduction of water to inner chamber of the spray head generates snow when the pressurized water is discharged to the atmosphere through the pressurized air. The spray head is stored within the housing when not in use to eliminate any hazard to skiers and the labor required to utilize a portable snowgun.
