Product Information Color changing beads actually change color when exposed to sunlight! Ultraviolet Beads "glow" with bright colors when exposed to the sun 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: sunglasses, sun-block, and automobile glass for example. Combine science and art to create jewelry and other fun art projects using the beads. 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 contains approximately 240 UV beads.  Tell a Friend about this item
