Glow in the Dark Powerballs by Horizon Group USA, DIY STEM Kit

Discover a world of fun and create your own Glow-in-the-Dark Power Balls with the new and improved Made By Me set! First, decide which mold you'd like to use - round or hexagon - to begin crafting your first power ball. Next, select from 18 bags of crystals to design your unique creation. Carefully pour the crystals into the funnel at the top, making sure not to fill it all the way up, so your power ball can bounce as high as possible.

Submerge the mold in warm water, let it sit for ten minutes, then gently pinch the tabs or un-snap the mold to reveal your new power ball. Drop it on a clean, flat surface to see how high it bounces, and then create more power balls for bouncing competitions with your friends!

The new and improved power ball molds make assembly easier than ever - simply snap the sides together and pinch the tabs to release. Experiment with 18 bags of colorful and glow-in-the-dark crystals to make every power ball unique, playing with fun color combinations and glow-in-the-dark effects.

Ready to play in just 20 minutes, the set includes 2 Round Molds, 1 Hexagon Mold, 16 Bags of Crystals, and 2 Bags of Glow-in-the-Dark Crystals, along with easy-to-follow instructions.
