Inner Tube Water Polo  is a super-fun variation on the game of water polo, but requires no experience to play and enjoy.  The game must be played to truly understand, but here's a brief run-down:  Sitting in inflatable inner tubes, players work together to score goals by throwing a ball into the net of the opposing team.  And you're allowed to flip players out of their tube when they have the ball...but be careful...they can flip you, too!  Teams of 12 play 6 on 6 for two 20-minute halves, making Inner Tube Water Polo both totally fun and a great cardio workout!
