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.
