A toy hoop that in a relatively small diameter is useable as a flying ring which when launched by a player then spins in the air, and in a larger diameter as a Hula-Hoop which whirls about the player's body. The hoop is composed of a planar annulus of non-stretchable, non-woven plastic sheeting having circular inner and outer peripheries, and a spring metal ring concentric with and joined to the outer periphery of the annulus whose inner periphery is free. In the flying toy mode of the hoop, the annulus functions as an air foil to impart aerodynamic properties to the toy. In the Hula-Hoop mode, the annulus functions as a protective soft inner liner. To reduce the hoop to a compact state, the ring is twisted 360 degrees to create an endless coil having three intermeshing convolutions whose diameter is about one third that of the untwisted ring.
