Champion Sports Coated High Density Foam Balls, 4", Model: HD4

Soft enough, yet heavy enough to use in the classroom for greeting activities.

I use this 7" foam ball to shape my cotton hiking hat and cotton flat cap while it dries after wet cleaning them. I wear size 6-3/4. It maintains their shape without stretching or shrinking. The ball compresses with just the right amount of firmness.

Ok so this ball is not like the ball they had me using for my leg workouts at physical therapy... It's much firmer. I did however buy two. This one and a blow up one that was less than half the price for this. I honestly do use the blow up one a lot more. But I suppose it all depends on what you are looking for.Say If I wanted to play dodge ball with the kids out back in our yard, this would be a great ball. But it wasn't really for my purpose. I'm not really much a returning sort of person so I just kept this baby for the kids. If you're looking for a squish type of ball- this isn't it. It's a nice ball otherwise...

I bought this foam ball for a science experiment. It’s called “cannon ball”. You drop some isopropyl alcohol in a one end-closed pipe. Stuff the foam ball on the opposite side. Rotate the pipe to allow alcohol to vaporize inside the pipe. The pipe has a small hole on the side closer to the closed end. You fire it and it shoots the foam ball. I’ve tried these multiple times and it worked well. The ball is squishy and it comes back to original shape after squeezing and releasing. I loved them. They look exact the same as in the picture with out the brand logo in them. It’s just plain yellow.

Bought this ball at the request of my son. The ball is average, but I think it’s overpriced. The dog got a hold of it and ripped several foam chunks out of it. The ball is still usable, but Definitely not worth the money I paid.

The ball is dense foam. Doesn't bounce really high. Great for my project!

Perfect

It Crumbles and was not as shown. It did not have any wording on it. It did not say Champion on it. I ordered this for pilates knee squeezes. It arrived in a clear bag that had a cellophane like feel. There was no identification on the bag. There was no identification on the ball. When I took it out it felt like it was covered in sand. I had little granules all over my hands. I tried one exercise with it and I ended up with yellow granules wherever the ball touched my clothing. I tried brushing it , then rinsing it, but this made no difference. I still end up with granules on my hands and clothing. I know some people commented that it was good for playing with kids, and perhaps they received an actual Champion brand and it may have been better quality, but I would never give the one I received to a child. Those crumbles can't be healthy.... I am returning it. Even if it was marked down to only 50 cents, I wouldn't want it. I am too concerned about the potential toxins.
