Abstract: An aerodynamic flying disk, i.e. such as a FRISBEE®, comprises a circular disk body having a circumferential rim. A groove is provided in the rim. A plurality of light sticks are located in various sections of the groove. The light sticks are bent and snapped to activate a chemical light producing reaction and after such activation may be placed into the sections of the groove. Thereafter, during the time the light sticks continue to glow, the flying disk when thrown and flown through the air will have an illuminated circumferential rim, enhancing the user's enjoyment in using and/or playing with the flying disk.
