A toy flip cap adapted to be sailed through the air by means of placing the cap between the thumb and the middle finger and then snapping the fingers, the cap thus being flipped outwardly to travel along various flight paths. The flip cap comprises an annular body defined by a substantially flat top wall having a flared peripheral depending wall. The peripheral wall is the portion of the cap that is held between the thumb and the middle finger, and it is designed to provide an aerodynamic lift by the force resulting from the snapping of the fingers.
