Watermelon Ball Pool Toy Review

There are a lot of toys that claim to be “the ultimate pool game-changer,” but most of them are just glorified beach balls that give up on life after a few sunburned afternoons. The Watermelon Ball, however, is a different beast. It’s a green-striped, semi-submerged cannonball disguised as a refreshing summer fruit. You fill it with water using the included hose adapter (because it’s too sophisticated for good old-fashioned air), and voilà—you have a ball that sinks, rises, bounces, and occasionally attempts to take out an unsuspecting cousin during a game of underwater keep-away.

Durability and Pool Play

I’ll admit, I had my doubts. I’ve been burned before—well, not literally, but emotionally—by “indestructible” pool toys that split faster than a cheap beach umbrella in a wind gust. The PVC felt sturdy in our use. Once the full-size ball is filled with water, it is much heavier than a normal inflatable pool ball. Published product listings disagree on the exact filled weight, so I would not rely on a single number; the important practical point is that the weight is part of what makes it behave differently underwater. You can dribble it like a basketball, toss it like a medicine ball, or watch it rise to the surface in slow motion like it’s auditioning for a dramatic action-movie scene.

Who the Watermelon Ball Is For

It’s not perfect. If you’re expecting to play catch with it above water casually, you’ll quickly learn the meaning of “heavy catch regret.” And if you’ve got smaller kids, you might be the one doing most of the tossing. But for pool parties, beach trips, or backyard cookouts where people want to do something other than float aimlessly on inflatable pizza slices, it’s a winner.

How Watermelon Ball Worked in the Pool

If you want to give your summer gatherings a shot of competitive chaos, the original Watermelon Ball is designed to be filled with water using a hose adapter and used for underwater passing, dribbling and bouncing. Because the full-size ball is heavy out of the water, smaller children may need help handling it.
