  • Great purchase
This ball is sturdy and loved my both young and old. It’s a favorite toy in my pool!

  • Simple but surprisingly fun
The HydroSport Plunge Ball is a thick rubber ball that you inflate with water. My 6 year old found it immensely fun to play with in the pool. I found that the ball works best filled with mostly water and just a small amount of air. I didn't do it this way but I would suggest starting by only adding water and seeing if there is enough air in the ball already to make it float just slightly above the surface. Don't leave the ball unattended while adding water. The inflation needle limits the flow of water so inflation is slow but the water pressure in most house would lead to a rather spectacular explosion if one forgot about the ball while connected to a water hose. Despite product claims to the contrary, I don't think the ball will sink fast even if fully filled with water. In any event, I would be sure to have a little air in the ball so it will float to the surface. It is pretty heavy and I am not sure if a pool net could lift it from the bottom. ... show more

  • Simple Concept but Great Fun!
I got this to play with my toddler in our pool and it worked absolutely fantastic for that! He was laughing as I pushed the ball towards him and he pushed/kicked it back. He also enjoyed when I threw it up into the air and it sank down to the bottom of the pool. I could also see this being fun with other older kids and even adults who want to toss the ball around under water. it is fairly heavy when filled with water, so definitely would advise keeping it in the water if playing with others. It was fairly straightforward to get setup,. There is an included garden hose adapter and a ball inflating needle with a rubber gasket on one side that goes into the adapter. You then just insert the needle into the ball and turn on the hose until it is filled with water. Super simple concept with a lot of replay value. I would consider this a staple pool toy for many years to come. ... show more

  • Performs as advertised
My kids are loving this ball. It is heavy when out of the water but buoyant while in the water. That love that they can bounce it and pass it under water. They are having so much fun with it. I just had surgery so we are spending the summer at home, this ball is definitely helping to keep the kids entertained while I’m down. ... show more

  • Really cool!
This ball is pretty cool! It's much heavier than I expected, even when it's just filled with air. We've tried it with all air, half water/half air, and full water. Full water is too heavy for my young kids. Even with half water, it feels like a bowling ball. But it is super cool how it can be half submerged in the water, and it's a lot of fun to play with. Everyone at our community pool asks to play with it when we bring it, and it is especially loved by our neighbors who are between 10 and 14 years old. It is easy to inflate and deflate and the quality is great - very durable. Make sure you bring the pump and attatchments with you if you are bringing it somewhere. Overall tons of fun and very versitile. Highly recommend! ... show more

  • The kids love it!
This ball is a great way to teach young new swimmers how to swim under water. The ball doesn't pop up like a regular ball and requires the swimmer to retrieve it. It's been a very good swimming learning tool as well as a fun pool activity.
