How does it work?
Don't blink your eyes because our color-changing beads have a new formulation that makes the beads more reactive to the sun and the colors more vibrant. The solar-active pigment keeps the beads from permanently discoloring and speeds up the time it takes for the beads to change back to their original white color. The UV-sensitive beads contain a pigment that changes color when exposed to ultraviolet radiation from the sun. The energy beads are not affected by light from light bulbs that do not emit ultraviolet light. The beads will remain white indoors, when shielded from sunlight.What does it teach?
Use the beads to teach kids about the ultraviolet radiation and the care that needs to be taken to prevent the damage it may cause. Ultraviolet (UV) light is the invisible radiation that will give you a sunburn and injure your eyes if you're not careful. Sunglasses and sunscreens absorb UV photons. You can test their protective qualities by using your UV detecting beads.
Experiment:
Test your sunglasses by placing them in the sunlight and covering a few of the energy beads with the lenses. If the beads remain white, then your sunglasses are blocking harmful ultraviolet rays.
Test the effectiveness of your sunscreen by coating a few of the beads and placing them in the sunlight. If they change color, better buy some more cream! Manufacturers suggest that you throw away sunscreen that is over a year old because it loses its effectiveness.
Product FAQ
- Do the beads fade over time?
After we left the beads out for the entire day and brought them inside, they returned to white.
- How long do the beads last?
We still have some of the original batch from a couple of years ago that are still going strong.
- Are the colors in the 1,000 pack packaged separately?
Yes, the colors you get are red, orange, yellow, blue, purple and now green!
- How many bracelets will the 1,000 pack make?
In general, a good bracelet requires 12-15 beads, which means you can make about 65-85 bracelets with the 1,000 pack of beads.

UV Beads are terrific
These were a HUGE hit with both Pre-K and KG students. When it's cloudy the colors are very pale & the yellow stays white; but the more sun the brighter the colors and the faster they change. They do take a few minutes to fade, and longer to go completely white again, but my students can't get enough of them. Months later they still work great. My only complaint is you don't get an equal amount of each color and I couldn't figure out how to block the rays with sunglasses and still see the beads without exposing them to the light. I wear my bracelet a lot here in California to remind me to put on sunscreen. I'm definitely ordering more. Thanks Steve!! |
