A device for producing a simulated snowfall comprises a display tank (20) filled with water and a plurality of small pellets (30). A pump (34) positioned on the upper side of the display tank (20) creates water currents which flow around the perimeter of the display tank. The water is propelled out of the pump (34) into an outflow tube (38) extending down a first side of the display tank to a receiving trough (32) positioned along the bottom side of the display tank. The pellets (30) decend through the water to the receiving trough (32) and are then carried horizontally across the receiving trough by a water current to a deflector plate (48) which diverts the pellets and water current in an upward direction along the second side of the display tank. As the pellets reach the upper side of the display tank, they spread out uniformly and gradually descend through the water creating a simulated snowfall with a natural appearance.
