<p>PURPOSE:To prevent a ball from being tampered by a crow by allowing a smell and taste disliked by the crow to penetrate into the surface of the ball. CONSTITUTION:The surface 2 of a ball 1 is devised such that a smell and taste disliked by a crow are allowed to penetrate into the surface 2 part. Such processed golf ball is used only in a golf course where crows inhabit, so that the smell and taste disliked by the crows prevent the ball from being tampered, particularly taken in their beaks and brought away by crows coming near the ball.</p> |
