Cool beads that teach a lesson The title of "Solar Energy Beads" is a bit mysterious, but what they REALLY do is to let kids be aware of ultraviolet light. They won't change color in the strongest indoor light, but even a cloudy, overcast day will change them from pearl-white to purple, pinkish-red, pale blue, or yellow very quickly. Kids can test "sun screen" effectiveness by putting beads in small plastic bags coated with each product and seeing which keeps them from changing color the longest. But I've been handing each kid a bead to put on their keychain or backpack so they'll KNOW when there's UV light around and they can think about sunscreen. As I said, UV makes it through overcast but no kid believes you — until they see these beads change color on a bright cloudy day. My skin is far northern European. It has two colors: white or red. It doesn't do "tan". Sun damage is a real problem and these beads remind you to protect yourself. My daughter is going to be handing them out at summer camp where she's a counselor this summer. They'll test the sunblock they brought with them to camp to see which needs to be reapplied most often. But they're just cool things to have around for kids to see turn color and realize sun CAN be harmful, even on a cloudy day. June 12, 2014
