Demonstrate The Presence Of Ultraviolet Light With Color-Changing Beads

Your students can't see ultraviolet rays, but they'll know they're there with these special beads. Have your class make bracelets or necklaces while the beads are white, and then wear them outside. When they see that the ultraviolet-sensitive pigment changes colors, even on a cloudy day, your young scientists will understand that UV light is around them, even when they can't see it. The beads will revert back to white when they are no longer exposed to UV rays and will change over and over again without fading. Includes approximately 2,500 beads that change into assorted colors.

Approximately 2,500 white beads that change into assorted colors, with hole for stringing
Size: 6 mm by 9 mm each, with 4 mm hole
Colors: Beads turn red, orange, yellow, green, blue, and purple
