Lawn sprinkler

A lawn sprinkler comprising:

• a fluid nozzle arranged in such a way that they mimic the geometry and function of a flailing hose, having no stable point of rest and therefore moving erratically and randomly in response to flowing pressurized water passing there through discharging water, wherein said fluid nozzle further comprises:
• a lower ridged conduit rotationally connected to a water intake at a lower terminus;
• an upper rigid conduit extending above the sprinkler pattern guiding structure;
• and
• a flexible connection joint connecting a lower terminus of the upper rigid conduit to an upper terminus of the lower rigid conduit wherein said flexible connection joint is a directionally pliable flexible tube;
• and
• a user-definable area, said user-defined area formed by a sprinkler pattern guiding structure forming an annulus having an adjustable shape and circumference and through which the fluid nozzle passes and creating a limitation restraint that limits movement of the flailing fluid nozzle to an area defined by the sprinkler pattern guiding structure to create an overall water spray pattern concomitant with the user-defined area.
