Abstract
Abstract The invention relates to a hockey puck which is weighted to provide a practice puck to improve the player''s shooting strength and accuracy and his passing and puck control. This is accomplished by incorporating into the resilient body material of the puck a material having a specific gravity greater than that of the resilient material to provide the finished puck with a weight greater than 5.5 to 6.0 ounces. The resilient body material may be rubber or like material and the material incorporated may be in the form of a core, or plates or discs or spheres, or may be particulate or granular.
