PURPOSE: A floating golf ball is provided to improve buoyancy property of a ball and to maintain elastic strength of the ball. CONSTITUTION: A floating golf ball comprises a metal core(110) which has specific gravity smaller than that of water and high elastic stiffness. The metal core is made of foamed aluminum. Since the core is made of a metal with improved elasticity, a golf ball with the core maintains elasticity. The golf is able to float on the water due to lower specific gravity. |
