Steve Spangler Science: Revealing UV with Color – Changing Beads

Dangerous ultraviolet (UV) light can be revealed using simple, white beads

Knowing you’ll spend some time in the sun, you carefully spread a sunscreen lotion labeled “SPF 50” on exposed skin. The next day, you look and feel like a steamed lobster. What happened?! Instead of using your skin as a UV detector, do a test with simple white beads to see if the sunscreen you are using is effective. These beads change color when exposed to UV light. Knowing the effectiveness of your sunscreen will make your sun time more of a fun time.
