In some embodiments the present disclosure provides a sprinkler comprising: a nozzle for projecting a stream of liquid in a first direction; and a spinner having a liquid deflecting surface, which is pivotally mounted in-line with the nozzle such that a stream of liquid from the nozzle impinges on the liquid deflecting surface; where the liquid deflecting surface is shaped such that the stream of liquid causes the spinner to spin and furthermore, where the liquid deflecting surface is shaped such that the stream of liquid is deflected in a second direction that is substantially transverse to the first direction. Additional embodiments of this disclosure pertain to the sprinkler that includes a frame, where the spinner is pivotally mounted on the frame.
