Abstract: A method for creating fluids flow; comprising a minimal spiral having at least one helical curve on the spiral. The spiral can be a continuation of a motor shaft or attached to a motor shaft by any means suitable, depending on use. The spiral can be made of any flexible and/or resilient material, metal or plastic and can be formed in motion as a resilient rod, preferably tapered, revolves in fluid medium describes at least a single helical curve on the rod forming a minimal spiral. The helical curve of the rotating spiral can vary the volume of a single frequency amplitude of the curve and so is the rate of flow, depends on an output of a motor. By increasing the volume frequency vibration of the amplitude of the helical curve of the spiral, the spiral reducing the frequency and the rate of flow and by reducing the volume frequency vibration of the amplitude of the helical curve of the spiral, the spiral increases frequency and the rate of flow. By conforming a structure of the minimal spiral to the structural dynamics of the flowing fluids allows the structure of the minimal spiral to balance the tension compression between fluid and the helical curve of the spiral. As the resilient rod depends on the frequency revolutions of the rod relative to fluid finds the tension or mutually opposed tension compression force between structure of the fluid and the structure of the revolving minimal spiral. Thus, the capacity of the spiral to conform to the fluid prevents what is known as slip of propeller, which reduces efficiency of the known methods, as the result of so called a cavitation effect of fluid under pressure.   Accordingly, a dispenser having a hollow body; to receive a fluid; the body being generally cylindrical and having a first end and a second end; an outlet for the fluid at the second end of the body communicating the interior of the body with the exterior of the body; an opening at the first end to permit air access to the body to allow flow of the fluid through the outlet; a spiral within the hollow body able to rotate relative to the body and to the fluid to convey fluid through the outlet; a spiral is able to extend at least one helical curve of the spiral to a point adjacent the outlet and being a minimal spiral, having single volume frequency vibration of the amplitude of the helical curve of the spiral extending from one end to the other end of the body; and thus, the minimal spiral is of minimum volume; having minimal helical curve on the spiral occupying only minimum portion of the volume of the interior of the body and is able to change the volume of the frequency vibration of the amplitude of the spiral to conform the volume frequency vibration of the amplitude of the spiral to the volume frequency vibration of the amplitude of the flow of fluid to the interior of the body so that the spiral remains closely adjacent to the interior of the hollow body throughout the body, where rotation of the spiral relative to the body and to the fluid convey fluid from the body through the outlet. Thus, the use of the minimal spiral in the dispenser allows for control of the frequency flow through the body and through the outlet to enable the dispenser to operate intermittently.
