Abstract: A display apparatus for providing entertaining visual aesthetic effects utilizes pressurized flowing air to propel lightweight beads into the air in arc-shaped trajectories which suggest the paths of water droplets from a water fountain. The beads are propelled upwardly from tubular bead discharge nozzles which protrude upwardly from a collection platform. Each nozzle has therethrough a bore which has a lower entrance opening for receiving pressurized flowing air, and circumferentially spaced apart bead entrance notches which penetrate the tubular side wall and a lower transverse end wall of the nozzle adjacent to the collection platform. Beads which have been propelled into the air and fallen back onto the platform are drawn into the nozzle entrance opening by a venturi effect, thus providing a recirculating levitated beads fountain display.
