An artificial snow machine for display purposes includes a cylindrical container having an inverted conically shaped bottom. High pressure air is admitted to the interior of the container through a port at the apex of the cone to pressurize the container. A motor driven fan is mounted on the top of the container, the fan blades being inside the container. A plurality of rotatable elbows provide communication from the interior to the exterior of the container through the sides and near the top thereof. The container is adapted to be filled with artificial snow material, such as small plastic pellets, to a level approximately two-thirds the height of the container. Circulating air from the fan blades churn and suspend some of the pellets, some of which are carried from the pressurized container by the escaping air. A shroud around the fan blades prevents pellets from striking the blades. Pellets leaving the elbows, or hoses connected thereto, form a screen as they fall.
