A display apparatus (20) includes a blower (44) which provides a pressurized flow of air to lower air inlet openings of tubular nozzles (35) which protrude upwardly from a collection platform (21) to thus propel lightweight beads (56) from an upper bead discharge opening of a bore (41) through each nozzle into arc-shaped trajectories which simulate flowing water. Each nozzle (35) has a plurality of circumferentially spaced apart openings (58) through the cylindrical wall (57) of the nozzle, adjacent to the platform, for drawing into the bore of the nozzle by a venturi effect beads (56) which have fallen onto the platform. One or more illumination sources (63) spaced radially apart from the nozzles (35) illuminate the airborne beads (56).
