A sound toy, essentially characterized in that it is constituted by a hollow, cylindrical tube, annularly grooved on its entire surface, both internally and externally, of great length compared to its diameter, and constructed of an elastic and flexible material, which grasped by one of its ends, in such a way that the passage of air is not obstructed by its interior, and making it rotate conveniently, causes, by virtue of the shock of the air with the annular grooves of which it is provided, a peculiar sound, which changes from tone and intensity, by varying the speed of rotation of the tube.
