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.

My grandsons love this!

I didn't know exactly what to expect...but my son and grandsons think this is great. They love playing with it underwater. I the ball is smaller than I expected compared to this picture, but perfect for my 7, 10 & 40 year old swimmers.
Seems well made. You fill it with water so has a good buoyancy. Not sure why it is recommended for 8 yrs up unless the swimmers ability might be an issue plus the weight of the ball.

A hit in the pool and with grandkids!!!

7/12/2019 by Marcia

What a great thing for having fun at the pool. Innovative and great exercise. From seniors to 5 year olds, this underwater ball is a "ball of fun" Easy to fill with great instructions. Once you get the jest of passing underwater, this watermelon ball can be played with from two or more swimmers. Eyes are all on those playing, as most people have never seen it before. I eagerly tell them about it and how it was invented, science of a watermelon. We have even let total strangers play with it because of the interest. If you want an unusual and new form of pool fun, this is the thing for you.More > < Less

How come this ball won’t float or sink?

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.
