Underwater Rugby

Underwater rugby is pretty simple, teams of 12 (of which 6 can be in the water at a time) battle to get a ball into two metal baskets, set at opposite sides of the pool.The ball is filled with a saline solution, which makes it heavier than normal water and slowly sinks instead of rising to the surface. This allows strong players to throw and pass it for a few meters, despite the drag of the water
