NOVELTY - The toy has an inlet (22) directing water into a housing (20) and multiple outlets (24) allowing the water to exit as a stream or a spray. A water turbine (32) within the housing rotates in response to the force of the flowing water. A rotation of the turbine operates a generator (38) to create electrical energy to light a light source (42) e.g. light emitting diodes. The light source responds to a control signal generated by a controller (44) in an assembly carrying the light source. A chamber of the turbine is made of a transparent material.    USE - Used as a fountain that is utilized in a bathtub toy, as a sprinkler for cooling off children on a warm summer day, as a water nozzle, as an outdoor location e.g. as a yard or garden, in a toy industry, shower or bathtub or swimming pool, and for entertainment and decorative purpose.    ADVANTAGE - The rotation of the turbine operates the generator to create the electrical energy to light the light source, thus preventing electrical shock hazard and eliminating the need for a battery, and hence eliminating a special compartment to keep the battery and associated circuitry dry, avoiding access to the light circuit by children, and reducing material costs for a manufacturer. The light source responds to the control signal generated by the controller, thus varying the color and frequency of the light source based on the movement of the water. The chamber of the turbine is made of the transparent material, thus enabling to see the working of the turbine.
