Learning benefits
- 💡 This activity introduces kids to polymer chemistry and cross-linking in a tangible way. It practices precise measurement and sequential following of instructions, while building hand strength through rolling.
Safety notes
- ⚠️ Adult supervision is required when handling borax powder to ensure it is not ingested or inhaled. Ensure children wash their hands thoroughly with warm soapy water immediately after molding the ball and playing with it.
Cleanup
- 🧹 Wipe all sticky surfaces with a wet sponge and warm soapy water right away. Discard the disposable plastic cups and wooden stir sticks in the trash bin, and store the finished bouncy balls in airtight plastic bags so they do not dry out.
