Abstract

PURPOSE:To make the surface of water cloudy and to obtain a screen surface for projection by installing a pressurized air supplying mechanism jetting air from nozzles set under the water surface toward the water surface. CONSTITUTION:Pressurized air is fed to a pressure regulating tank 15 with a compressor 19 to regulate the pressure, and it is jetted from the nozzle hole of each nozzle 8 toward the surface 4 of water through a pressurized air supplying pipe 12 and a distribution pipe 10. As a result, the water surface 4 is made finely cloudy all over to form a screen for projection.
