  U.S. Class: 40/409
Abstract:  A water flow simulation system for audio and visual illusion has an inner conduit and an outer conduit spaced apart to define a flow channel therebetween. A blower directs a flow of air through the inner conduit from one end to an opposite end where at least some of the air exits and is redirected through the flow channel and back to the blower. The conduits are formed of clear plastic and a light source is positioned to light up a plurality of objects floating in the airflow to produce a visual effect of moving water. A sound source operates concurrently with the blower to produce a sound reminiscent of rippling water. The light source can change colors and strobe to enhance the visible image. A lenticular lens on an inner surface of the outer conduit also enhances the image.
