A water toy has a cylindrical deflector mounted on top of an upright hollow pipe that is rotatable about a vertical axis. Pressurized water introduced into the pipe is ejected from a nozzle fluidly interconnected with the pipe wupwardly onto the deflector along a plane which is offset from the deflector axis. The stream of water from the nozzle causes the deflector to rotate which in turn causes water to be thrown off of the periphery of the deflector into an umbrella pattern. If the nozzle has a concentrated spray pattern the umbrella spray is thin and covers a relatively large diameter, and if the nozzle has a fan-shaped spray pattern the umbrella spray is thicker and covers a relatively smaller diameter.
