Nerf Super Soaker Hydro Balls are reusable water-filled balls that burst on impact to splatter water everywhere! They're fast and easy to refill to keep the water-drenching fun going in outdoor Nerf Super Soaker games. This set includes 6 Hydro Balls toys in 2 different colours. The balls are made with a soft, flexible material. The balls separate into 2 interchangeable halves, so it's a cinch to put them back together for quick refilling. And filling them up is easy! Attach the halves, dunk the balls in water, squeeze them, and you're ready to go. And after throwing them, cleanup is quick, just pick up the halves and refill. They're great outdoor water toys for 6 year old boys and girls, and lots of fun for everyone. The Nerf Super Soaker brand has been pouring on the fun since 1989 and continues to drench kids, teens, and adults with lots of water-blasting mayhem! Dry thoroughly after use.
