UV Beads, Change to Blue, Ultraviolet: Educational Innovations, Inc.
Watch white beads change to blue when taken outside the building! When returned they turn back to white. What causes the change? Humidity? Temperature? Fresh air? Birds flying overhead? The beads contain pigments which react with ultraviolet light from the sun, even on a cloudy day. They also change with most classroom UV light sources. Students can make their own UV light detecting bracelet by stringing the beads on a pipe stem or on a strip of rawhide. Great for teaching UV awareness! Use the beads to test the UV blocking effectiveness of sunblock, sunglasses, windows, etc. Lesson activities are included. The ultraviolet beads will cycle back and forth (to blue and back again) over 50,000 times! Approximately 250 beads per package. All of our UV beads are the same size. Approximate bead dimensions: diameter 8.5 mm (5/16") - center hole 3.6 mm (9/64") Read more on our Blog - Chemistry of Ultraviolet Detecting Beads with Video Read more on our Blog - UV Radiation Activity
