PURPOSE: To provide a special effect such as a fountain itself emits light so as to float up in darkness when it is dark in surroundings as at night, and the like by making radiated light from a light emitting portion pass through the jet of the fountain and transmit along a jet direction, and also making the light transmitting inside radiate outward from the surface thereof. CONSTITUTION: A fountain device 16 is equipped with a jet portion 17 composed of a nozzle, and the like. The jet portion 17 is provided in a water vessel 4 in a state that the discharge port 3 appears from a water surface, and is coupled to a water supply pump 5 provided outside the water vessel via a discharge tube 6. When the pump 5 is driven, the water in the water vessel jets upward from the discharge port 7, falls drawing a parabola, and returns to the water vessel 4. Radiated light 25 from the light emitting portion 23 of a lighting system 15 transmits inside a fountain 18 through the discharge port 3. The light radiates outward from the surface of the fountain 28 so that the whole fountain 18 jetting from the jet portion 17 emits the light. |
