Loved doing this with my grandson. So much fun! Easy to follow directions

I got these kits for my daughters for Christmas. They had a great time making them and it was really pretty easy. The resulting balls looked surprisingly great and bounced almost as well as a vending machine ball. There texture was a little rough, but it didn't affect the bouncing at all. We were all really happy.After a few days the balls were forgotten about.That's fine. But when I found one a couple months later it wasn't bouncy anymore. It was hard as a rock, and bounced like a rock too. That's no big deal, but just know that the balls are a temporary toy and won't last long. No one cares though - most of the entertainment was the fun of making them.

Got this for my grandson for Christmas and he loves it we made some today the day after Christmas all kind colored it’s very easy and simple and it does bounce just to see the smile on his face is priceless he’s 4yrs old

You get what you pay for. It served its purpose which was to entertain my child and be something other than here’s an iPad. The molds don’t snap together very well. The balls themselves don’t bounce very well and if you want to keep them you have to put them in a bag and keep them moist which let’s be honest is t going to happen. I wouldn’t give it as a gift but if you’re looking for something to entertain your child for an hour it perfectly fine.

This was exciting and turned out great. Be sure to tap the powder down before submerging in water as it makes for better bouncing ball. We had a hard time with the blue molds as the didn’t hold together well. Used small funnels to fill for younger kids.

Big like :)

Birthday gift. He loved making his own bouncy balls! Everything worked out well - one of the plastic moulds didn't close together well and it popped open at one point.When I received the package, it was spilling out some of the green colored material which made a bit of a mess and lost some product, but there was plenty of enough still to make several balls.
