Abstract
There is disclosed a modified throwing object, such as a modified football or frisbee, and a corresponding glove or wrist strap or finger-band worn by each player. Both the object and the gloves or wrist strap or finger-band are covered with coacting elements which are preferably a limited amount of the material comonly called velcro. This material attaches to itself by its well-known design of fabric hook pieces gripping onto fabric loop pieces. The invention is so designed that then the object is held in a typical throwing position, prior to being thrown, there is interaction between the velcro on the glove and the velcro on the object. Upon release of the object during a throw, the bond between the velcro on the object and that on the glove, wrist or finger of the thrower is separated with a slight difficulty, thereby casuing the object to spin as it leaves the thrower's hand. This spinning of the object on its longitudinal provides the desired spiraling action that greatly enhances the accuracy and speed of an object such as a football as it travels through the air, or the spinning action which improves the distance and accuracy of a frisbee.
