Abstract: A rotary aerial toy comprising a tubular sleeve of flexible material and of circular cross section. In one form of the invention the tubular sleeve tapers from one end toward the other with air entering the larger head end and moving toward the tail end. The head end is adapted for a bridle connection for supporting the sleeve for wind passage therethrough. The sleeve comprises plural strips extending at least generally longitudinally of the sleeve with each strip being of substantially right triangular form, at least at the head end portion thereof. The strips are connected to one another with the hypotenuse leg of one strip being connected to the altitude leg of an adjacent strip and with the base leg being transverse. The strips are arranged at assembly with a step between the head ends of adjacent strips and the seams connecting any selected pair of strips stop short of the head end of the altitude leg of the strip.
