As a STEM teacher I bought these for an after school club. I was so surprised on how easy it was for grades 3-5 to complete. The only thing that was difficult for them was putting the powder into the small opening. Once I told them to place it on their directions and make a funnel and was a breeze. They turned out great and I plan on using them again. A little bit expensive but well worth the cost and ease.

Easy instructions for young kids. Pour provided powder into mold. Submerge underwater for 2 minutes, dry for 15 min before taking out of mold, dry for another 90 min before using.

I took off a star because if you don’t keep the ball moist it will get hard and not bounce. I gave it 4 stars because it was an awesome craft to do at a party for kiddos and they got it take it home. It takes an hour to settle so by the time they got home after making it at the party they got see what they made and play with them it. Win win because it’s a party favor and I didn’t have a bunch of bouncy balls in my place.

They were a hit in my kids birthday goody bags! Super easy and fun for the kids!

I loved these. We tested them at home before giving to my students. Works great. One of the balls did “dry up” and get hard after a month.

Did I get a flaw or do these not come with lids? It seemed like they had lids based on the pictures and the box. Also sadly, I received a box without any of the bouncy ball molds to actually make the product.Customer service was excellent and helped me get it all straightened out!

These were really cool. I bought them as party favors and we had a couple extra so we did them at home. It was fun. The kids got a little impatient with the process (there is a bit of waiting) but overall it was fun. They are really bouncy too.

I bought this to do with my grandchildren who love balls. Unfortunately, there wasn’t much they could do to make the balls as you have to have really good dexterity and fine motor skills to pour the crystals into the ball. But they could put the mold into the water. It was pretty quick to make, so that worked out well and they loved the results! They are 2 & 4 :). I’d say to do on your own you have to have good coordination of fine motor dexterity and not be a perfectionist!
