The kids enjoyed creating these and the balls bounced really well!

I didn’t want candy in my 9yr olds birthday favor bags ; so I used these little make your own ball , along w/some other items & worked out perfectly!

I bought this for a quick and easy party activity and it was great! Little mess and very little effort. I will say that the bouncy balls were a little sticky when they were done but I think we needed to let it dry a bit more. The kiddos loved making these.

This was a great activity for my 4, 5, and 7 year olds. They had so much fun with the sand, shapes, and colors, and the balls look great and bounce well.

Received quickly. Bought it for my daughter's friends/cousins to make at her party and they all had fun!

Huge hit as party favor for my sons 6th birthday. Kids made them right away and everyone wanted more! So great!! Ages 3/4-8!!!

My kids had a great time making their bouncy balls - which really bounce! It's all they wanted to do last weekend! I would absolutely buy these again. We used them for a birthday party; my son's friend loved them too!

Super cool party favor for the older cousins. Highly recommend

Awsome, the kiddos had a blast! Worth the money!

Used these for party favors for a “super science” birthday party, and they were a huge hit! The kids (and even the adults) loved them! I might buy more in the future just for a fun activity with the kids. They are super easy to make.
