Steve Spangler Science: Blocking UV Rays

See how old prescription bottles have the power to block UV rays.

Don’t throw away your old prescription bottles. Solar science educator, Jim Stryder, shares a unique method of demonstrating the “power” of ultraviolet radiation (UV rays) for K-12 students using our Color Changing UV Beads and a plastic prescription bottle.

Upon refilling a prescription at his local pharmacy, Jim noticed a marking on his brown prescription bottle that read – “UV BLOCKING PLASTIC.” Being the solar science enthusiast he is, Jim immediately filled an empty prescription bottle with Energy Beads. To his amazement, the bottle blocked out nearly 100% of the UV light! Come to find out, many drugs are sensitive to damaging UV light, so the bottle is specifically designed to preserve the life of your prescription.
