How to make the bouncy balls
Layer the colored crystals into the mold, then submerge the mold in water for a few minutes. The crystals bond together to form a solid, bouncing ball. The glow-in-the-dark effect activates after exposure to light – charge them up and watch them glow in a dark room.
Who is this for?
Designed for boys and girls aged 8 years and older. Adult supervision is required because of small parts and the water-step. It makes a great Christmas or birthday gift for kids who enjoy science experiments or creative activities.

Frequently asked questions
Can I reuse the crystals for more balls?
The instruction guide does not mention reusing crystals. Each pack is intended for a single use, so you get exactly two large or eight small balls from the included sets.
How big are the finished balls?
The kit makes two large balls roughly the size of a standard bouncy ball, or eight smaller ones. Exact dimensions depend on how you fill the mold.
Does the glow effect require sunlight?
The crystals need exposure to a bright light source (like a lamp or sunlight) for a few minutes to charge. The glow fades gradually in the dark.
Is adult supervision really needed?
Yes – the small crystals are a choking hazard, and the water submersion step should be done with adult help. The packaging clearly states small parts and adult supervision required.
