<p>A puck for playing hockey on any type of surface consists of a relatively thick disc of plastic, wood or similar material. The undersurface (3) of the puck has three symmetrically positioned holes (2) to receive balls (1). The balls (1) are trapped in the holes (2) but are free to rotate. This feature enables the puck to slide easily on any type of surface such as asphalt playgrounds or grass pitches. The upper surface of the puck has a central taped hole into which a handle can be screwed to enable the puck to be used for other sorts of games.</p> |
