We also made bouncy balls. There is a pinterest post on this, however, I went with the easier version when we happened to come across a Rose Art Super Ball kit on sale at walmart for $3.00 when we picked up some glue sticks for future project.
Both boys love to play with bouncy balls. Now they get to make them! Highly recommend the kit!
Super Easy. Has ball mold and colors. Each ball only took 2 minutes to do, and 20 minutes to rest. We made 4 balls and still have more left over. They bounce well and make my boys smile. That is what it is about. Good day with lots of smiles and laughter. Hope your day brought joy as well!
