Creative Kids Magic Bouncy Balls - DIY STEM Toys - Science Kit for Kids - 25 Multicolor Bags & 5 Molds Makes Up to 43 Balls

The Creative Kids Magic Bouncy Balls kit is such a hit! My kids had an absolute blast making their own colorful, bouncy creations. Not only is it a fun craft, but it’s also a great way to introduce some basic STEM concepts like mixing and forming materials.The kit is easy to use, and the results are fantastic—super bouncy, vibrant balls that provide endless entertainment! It’s a fun, hands-on activity that kids of all ages can enjoy. Highly recommend as a gift or just a rainy-day project. Educational and fun all rolled into one!

This kit really works! It is easy and it took me and my six-year-old grandson less than an hour from set up to finish. We made four. The instructions are short and cleanup is easy. There is a powder that gets poured into a mold then it's submerged for two minutes. After 20 minutes the mold is opened to reveal the ball. It is sticky at first, but then not. It will not mark floors or walls. No smell and enough ingredients for many different balls. This is definitely giftable!

Fun and easy. They can get a little messy if you let your Littles do the powder themselves. They are sticky at first and after ours dried completely, became pretty hard and not as bouncy. My son still had fun and it was a great craft/project.They come with everything you need. The only thing you need to provide is water and patients! I recommend doing this on newspaper or paper towels and disposable cups. Tap the molds so the powder settles (especially in the square mold) before submerging into water. Also, if you are doing a lot...towards the end, the stickiness inside the molds will clog the water inlet holes. We had one big ball that didn't absorb water and it stayed powdery. Easy fix...we just added powder to fill hole and dried water onto it and molded it to match the Contour of the shape.UPDATE: Once fully dry, they are hard as rocks!

I bought these as prizes for a game at my son’s birthday party. We had planned to test them out before we gave them away because they look cheap and they were cheap. Unfortunately we didn’t have time to test them so I was really worried. HOWEVER, when we got home, we made 8 kits and all 8 of them turned out perfectly! We did have a couple that had been submerged all the way in the water (don’t see how that made a difference) that I was worried wouldn’t turn out because they were still fairly pliable when we opened them, but we just put them back in the mold and dried them on the table a few extra minutes. They were bouncy, colorful and so much fun! Each kid was proud of their ball and has lots of fun playing with them for a few minutes. We had kids ranging from 13 down to 2 years old make them at home and all of them enjoyed it. We did have to help the 2 and 3 year old pour the powder into the mold, but they still liked it. I would 100% recommend these for a party favor, fun activity at home, gift, etc.

I give it 3 stars because it's a very easy thing to do with the kids. But after day 2/3 they are not bouncy they become rock hard and do not bounce. They are a bit sticky when they are solid, fun activity though.

My kids had so much fun creating their own.

Kid really enjoyed it

The kids loved them and I did to.. The balls are actually bouncy when dry. I waited exactly 15 minutes before I let the kids take them out of the bouncy ball holder/container.
