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!

Such a fun activity

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.

These were fun to make. They bounced a bit when they were first done. Then they turned rock hard and could break a window.

Love this!! It was so easy to do! Literally 3 steps and it actually works! I was worried that they wouldn’t bounce high, but they do. My kids enjoyed making these. Would definitely recommend.

Fun kit- all inclusive- and the bouncy balls really do bounce! My 4 yr old grandsons loved this “experiment “. They were able to do it mostly by themselves (with a little help). Great activity for us to do together

I got these DIY bouncy balls as kids party favors, and I’m not a fan of landfill fodder. These kits were an absolute smash- complex enough activity for 7-9 yr olds but easy enough to require minimal adult involvement. kids came back asking for seconds! Like other reviewers stated the main issue was when kids didn’t read/follow the directions. If you leave the mix in the mold in water too long it wont set, etc. So parents/adults should give the instructions a read through before handing kits off to kids. For those who followed the directions, everyone had a fantastic, super bouncy ball!

時間が経つと固くなる 楽しく簡単に作れるから良いと思う

Listing shows box makes 43 balls, but the delivered item box shows that it makes 31 balls only. I needed this for something and don't have time to send it back and order another one.

Worked fairly well, and the price was ok.

My four year old absolutely loves these kits! It’s the second one she’s had and she is over the moon. The previous one (not exactly the same as this one) only made two bouncy balls so she’s very please this one will do more and that there are more varied moulds in the pack (cube, egg etc). Only downside to all these kits is that the balls do dry out and then don’t bounce anymore after a while.

We just used this at my son's 9th birthday party. It was very successful and all the children loved making bouncy balls. The large moulds use 3 sachets of granules so you could only make 8 of those in total. The square mould was very cool and produced an unpredictable bounce. It takes 15 minutes to set but found we could remove the mould earlier than that. Lots of fun.
