Date Dec. 28, 1989.Apparatus and a method are provided whereby snow is made in an indoor environment over extended periods. Within the indoor environment temperature and humidity conditions are set up to enable snow to be produced by a spray of water in the air. Such conditions are maintained for an extended time by the use of thermal storage means. The thermal storage means is cooled to a low temperature by coolant in turn cooled by refrigeration apparatus. The thermal storage means uses a mass of relatively high conductivity material through which the coolant is circulated and the coolant is used to cool and dry air to be discharged into the indoor environment.
