Underwater rugby? "An air-filled ball is not suitable for underwater games, since they are bouyant and always return to the surface. For this reason, Bersuda filled the ball with salt-water. Since the density of the ball was now greater than that of normal water, it no longer floated to the surface, but slowly sank to the bottom. The sink rate could, within certain limits, be controlled by the concentration of the salt solution. The first underwater ball was invented." Apparently, it's big in
Switzerland (located east or south of Germany). Anyone else know anything about it?
