Helpful Tips:
What makes glow in the dark bouncy balls glow?
We used glow in the dark pigment powder, which is commonly used in resin, nail art, and other craft projects. It charges under regular light and glows in the dark – no extra tools needed! However, if you want the bouncy ball to glow its brightest, hold it under a UV light for a minute first. For a simpler option, use Elmer’s glow in the dark glue in place of regular clear glue. You won’t need to add any pigment. Just mix with the borax solution and you’re good to go! You can also use glow in the dark paint mixed into clear glue, similar to the technique in our glow in the dark slime recipe.
How long do glow in the dark bouncy balls last?
These bouncy balls are best enjoyed the same day you make them. Since they’re formed from a soft, flexible material, they lose their bounce and shape as they dry out. If you store your bouncy ball in a round mold inside an airtight container, you might get another day or two of fun — but for the best bounce, we recommend making a fresh batch!
Do glowing bouncy balls really bounce?
Yes, they really bounce! These homemade bouncy balls might not have the same firmness as store-bought rubber balls, but they still bounce surprisingly well, especially right after you make them. These glowing bouncy balls are soft and super fun to play with. For the best bounce, toss them gently on a smooth surface like a tabletop or hard floor. Just remember: they won’t last forever, so enjoy the bounce while it lasts!
Why is my bouncy ball flat? Can I keep it round?
These bouncy balls are made from a thick slime-like substance, so they naturally start to flatten if left sitting. To keep them round longer, store them in a small round mold like a bath bomb mold, a mini bowl, or even a Tablespoon measuring spoon.
Is this a safe science experiment for kids?
Yes, this is a kid-friendly science craft that’s safe with proper supervision. The glow in the dark pigment we used is non-toxic and safe for skin. But like any craft involving borax, it’s important to follow basic safety tips. Avoid contact with eyes and mouth, wash hands after handling, and keep materials out of reach of younger children. If your child has sensitive skin or a cut on their hands, consider using gloves while playing. With a little guidance, this glowing bouncy ball activity is a safe and exciting way to learn through play! These glow in the dark bouncy balls are such a fun way to mix science and play! Whether you’re making them for a rainy day activity, a party, or just because they’re awesome, this glowing DIY is sure to be a hit. And the best part? These homemade glowing bouncy balls are quick to make and even more fun to bounce. Give them a try — you’ll definitely be glowing with excitement!
