Details

For your next swimming pool game, toss around a Watermelon... Ball. Modeled after a real-life watermelon, this rubber ball can be dribbled, kicked, passed, and bounced—all under water. Fill it up with water and a little bit of air to make it neutrally buoyant—its density will match that of the surrounding water, so it doesn’t sink or float. Instead, it stays suspended in the H2O.

  • Materials: PVC/TBC, natural rubber
  • Neutrally buoyant when filled with water
  • Looks, feels, and behaves like a real watermelon in water
  • Passes up to 10 feet in water
  • Bounce against pool walls
  • Can be bounced, dribbled, kicked, and intercepted
  • Made in China
  • Dimensions: 3.94" x 8.07" diameter
  • Weight: 1.28 lbs.

Wow - my great niece and nephew had a blast with this ball. They made up all kinds of games with it - kept them occupied for hours! In fact, time with it had to be divided up because they both wanted to be the boss of it!More > < Less

About Watermelon Ball

Waterballin'

Up your swimming pool game with the Watermelon Ball.

We’ll explain. Apparently tossing around a real-life watermelon in water as entertainment is a thing. They behave differently than most air-filled balls, so you can actually dribble, kick, pass, and bounce them—all under water.

The reason for this behavior—not floating, not sinking, and sort of suspending itself mid-water—is that watermelons are made of 92% water. That makes them neutrally buoyant. But real watermelons also break and make a mess...

The Watermelon Ball is made of tough rubber. You can fill it up with water and just a little bit of air to get it at the right buoyancy. Throw it up to 10 feet under water and combine elements of football, basketball, and rugby for some unconventional aquatic entertainment. Or toss it around outside the water, too.

Turns out no part of the pool is off bounds with this summer game changer.
