Just fill with water and get your game on! The Watermelon Ball is designed to look, feel, and behave like a watermelon in water. Real watermelons are nearly neutrally buoyant: first sinking to the bottom 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. The Watermelon Ball allows the user to play games that combine components of football, basketball, and rugby. The Watermelon Ball encourages exercises and active play in the pool. The extremely durable vinyl membrane stands up to intense action, features that are sorely missing from real watermelons. The Watermelon Ball is a swim toy that is great for kid, teens and adults. Excellent for pool parties and get-togethers.
