ABSTRACT:
An amusement device for simulating the appearance of snow including a window-like structure having a space between 2 front panes and a rear pane, where at least one of the panes is a transparent pane, and the panes are mounted in a frame support. There is a recycling system for circulating artificial snow, which falls down, from the top of the window-like structure and collecting at the bottom. The recycling system includes a trough with a rotating vane that opens and closes the open top of the trough, where one end of the trough is cyclically closed by and end cap on the rotating vane. The rotating vane is rotated by an electric motor. Another electric motor operates continuously rotating fan that blows the artificial snow from the trough through a conduit to the top of the window-like structure where it collects on a tray which is tripped to release the artificial snow.
