UV Detecting Beads

$0.55
SKU: UVBeads

The beads contain pigments that react with ultraviolet light from the sun, even on a cloudy day, turning them from white (no UV) to colored. Make your own UV light detecting bracelet by stringing the beads on a pipe stem or on a strip of rawhide. Great for teaching UV awareness! Use the beads to test the UV blocking effectiveness of sunblock, sunglasses, windows, etc. Available in five colors (purple, blue, yellow, orange and red), all beads are pale, off-white in the absence of UV light. The ultraviolet beads will cycle back and forth (to bright colors and back again) over 50,000 times.
