A snow making apparatus includes a cylindrical body and a snow making nozzle that jets water droplets into the cylindrical body. The cylindrical body has a proximal end that is opened to a temperature environment where snow can be produced from water droplets jetted from the snow making nozzle. A distal end of the cylindrical body is connected to a pipe member communicating with a test chamber. The snow making nozzle is formed of a two-fluid nozzle. The pipe member communicates with a snowfall hood disposed in the test chamber and having a supply opening that allows snow to fall. The cylindrical body is disposed in an oblique posture so as to be lowered from a proximal end toward a distal end of the cylindrical body.

An artificial snow-making facility includes: a snow-making device; a fluidic water pipe for supplying water to the snow-making device; potentially, a fluidic air pipe for supplying air to the snow-making device; a controller for managing the operation of the snow-making device; and a power supply for supplying electricity to the controller. The power supply includes a power generator arranged on one of the fluidic pipes, which power generator includes a turbine adapted to be driven by the fluid of the fluidic pipe.
