An apparatus (10) for making snow or a snow-like substance includes a container (12) having a cooling space (13) adapted to contain pressurized ai r or gas of above atmospheric pressure. At least one flexible walled vessel (1 4) extends through the cooling space (13) and is connectable to a water source. The apparatus (10) is operable to maintain the cooling space at a sufficient ly low temperature to at least partially freeze the water within the flexible walled vessel (14). As a preferred feature of the snow making apparatus, the apparatus may be adapted to maintain a static pressure within the cooling space of the container (12) and to periodically and temporarily increase the pressure within the cooling space to compress the flexible walled vessel (14 ). Invention also resides in an apparatus (10) for making snow or a snow-like substance, the apparatus including at least one flexible walled vessel (14) connectable to a water source. Spray equipment (18) sprays heat transfer medium onto the at least one flexible walled vessel (14) to chill the vessel sufficient to form ice crystals and/or snow within the vessel.
