Improved flying toy, essentially characterized in that it is constituted by an aerodynamic and lightweight body, in which at a thrust point it is provided with retention means in which fits a reactor constituted by a rigid and hollow body closed on all sides except for the rear one, in which an intake and outlet duct emerges, whose inside mouth is divergent conical, said reactor possibly being provided with valvular means that contribute to the admission inside the reactor of the pressurized gas necessary for it, when released by transforming the intake orifice into an exit nozzle, it propels the aerodynamic body in the opposite direction to the expulsion of gases.
