A whirling toy includes a weighted object such as a small bag filled with sand attached to one end of a string. Advantageously, streamers or other means are used to stabilize the toy while it is whirled prior to release into an upward trajectory. A target pattern or tape measure is used to determine the distance of the toy, after it has fallen to the ground, from the point of release. The toy may optionally be provided with means for producing an audible sound when the whirling toy velocity reaches a preselected threshold value. Such audible sound assures, if the toy is played competitively between two or more players, that all players have the same advantage since they all release the toy when it produces the audible sound and, therefore, reaches the preselected threshold velocity.
