PURPOSE: An apparatus for showing water flow is provided to express flexible water flow when a stream, a river or sea is implemented in a static model. CONSTITUTION: An apparatus for showing water flow includes a wave pattern perforated plate (100), a cylindrical drum (200), a drum driver (300), a light source (400) and a transparent plate (500). The wave pattern perforated plate comprises a metallic plate where a perforated part to transmit a light is formed. The cylindrical drum is surrounded by the wave pattern perforated plate, and assures an empty space in the inside for the light generated in the light source located in the lower part to pass. The drum driver is installed in one side of the drum, and rotates the cylindrical drum at a constant speed. The light source is located in the lower part of the cylindrical drum and irradiates the light to the upper part. The transparent plate is located in the upper part of the wave pattern perforated plate, and forms an image of perforated wave patterns by the light which has passed through the cylindrical drum and the perforated part of the wave pattern perforated plate after it is irradiated from the light source. |
