Product Information

These UV-sensitive beads change color when exposed to sunlight or other UV light source, but remain off-white when indoors or not in the presence of UV. Students can use UV Beads to design and conduct experiments that test the effectiveness of UV protection from sunglasses, sun-block, and automobile glass. String the colorful little UV indicators together to create necklaces or bracelets that double as UV detectors. Color Changing Beads will cycle back and forth 50,000 times for long term use. Assorted colors. Package of 240.
