UV Beads Crystak Bracelet
When the UV beads are exposed to daylight, even on cloudy days, they change from clear to coloured. Bring them inside and they turn clear again. The beads are not affected by regular light bulbs because they lack UV light. Try putting sunscreen on a bead and see the ‘UV Blocking’ effects. What else blocks UV? Try exposing the beads under a pair of sunglasses. The fun is endless.
