Made By Me Glow-in-the-Dark Power Balls Kit – Make 18 Bouncy Crystal Balls with Molds & Instructions
Create your own glowing, bouncy power balls at home with the Made By Me Glow-in-the-Dark Power Balls kit. This DIY STEM set lets you mix colorful crystals and glow-in-the-dark crystals to form 18 unique bouncing balls. The kit includes three easy-to-use molds (two round, one hexagon) and 18 bags of crystals – 16 colorful and 2 glow-in-the-dark. Simply pour crystals into the mold, submerge in warm water, wait 10 minutes, dry, and release. Each ball is ready to play in about 20 minutes. Ideal for kids who enjoy hands-on science and craft projects.
What's inside the kit?
- Molds: 2 round molds and 1 hexagon mold – snap together easily, pinch tabs to release.
- Crystals: 18 bags total – 16 bags of colorful crystals and 2 bags of glow-in-the-dark crystals.
- Instructions: Step-by-step guide included.
How do you make a power ball?
Choose a mold, pick your crystal colors, and pour them into the funnel (leave some space for bounce). Submerge the filled mold in warm water for 10 minutes. Remove and let it dry. Then pinch the tabs or gently unsnap the mold to free your power ball. Drop it on a clean flat surface to see how high it bounces.
