Watermelon Ball – the ball that’s designed to look, feel, and behave like a watermelon in water. Real watermelons are nearly neutrally buoyant; first sinking then slowly rising to the top, making them ideal for all kinds of water games. Watermelon Ball lets players dribble, kick, bounce, pass, and intercept under water. Watermelon Ball is extremely durable and stands up to intense action, features that are sorely missing from real watermelons. Just fill with water and get your game on. 8+ years.
