Get ready for hours of creative, hands-on fun! The Discovery Zone High Bounce Ball Kit includes everything kids need to design and make their very own bouncing balls. With 8 different mould shapes and enough crystals to create 16 balls, the possibilities are endless—flowers, footballs, spheres, polygons and more!

Choose from vibrant neon, shimmering metallic, or glow-in-the-dark colours and watch your custom creations come to life. It’s the perfect activity for rainy days, school holidays, parties, or gifting.

What’s Inside

• 4 metallic crystal packets

• 4 glow-in-the-dark crystal packets

• 8 neon crystal packets

• 8 assorted moulds (including shapes + sports designs)

• Full step-by-step instructions

How It Works (Fun Science!)
The crystals are made from polyvinyl alcohol (PVA)—a water-soluble polymer. When you moisten the granules inside the mould, they soften, swell and stick together. The long polymer chains tangle up, forming a stretchy, elastic material.
That elasticity is what makes your ball bounce! When the ball hits the ground, the polymer chains compress, then quickly spring back, pushing the ball up into the air again.

Good to Know

• Store finished balls in an airtight container to keep them bouncy

• Over time, balls may naturally dry out and lose some bounce

• Crystals are safe for skin

• If crystals get on clothing, simply wipe off with water

Make it, mould it, bounce it—bringing science and creativity together in the coolest way!
