ABSTRACT:
An aerodynamic rotor with pull-cord launcher toy adapted to attach a self-contained chemiluminescent light source to the rotor thereof, making the toy suited for use in the dark. The rotor includes one or more holders integrally formed into the blade(s) thereof for confining the light source therein. The light source is non-heat generating and creates a glowing shape of light when the rotor is launched and provides a source for locating the rotor when it lands. The rotor's shaft and the launcher's connector tube have an interconnecting design which enables them to easily be connected in the dark by feel. Some blades of the rotor have a small opening near their outer end to produce a whistling sound when the rotor is launched and rotates rapidly.
