Product Description
Ultraviolet Detecting Beads - UV Science and FunThese UV beads which wabe gift made are an inexpensive fun way to make the invisible become visible.The solar pony beads are pale in visible light, such as indoors or if they are shielded by a UV screen such as automobile glass or sunglasses. The Ultra-violet sensitive beads contain a pigment which changes color when exposed to UV light from the Sun or other UV source.Many of today's space telescopes observe colors of light not in the visible spectrum such as infrared and ultraviolet.One can make a simple bracelet from a standard pipe cleaner or strip of rawhide which can function as a UV detector. Use your imagination to think of other things to use them for.Many other experiments are possible as well... test sunglasses for the effectiveness of their UV protection, or even suntan lotion.In seven assorted colors, all beads are pale, off-white in the absence of UV light.The ultraviolet beads will cycle back and forth (to bright colors and back again) over 50,000 times!Become an ultraviolet detective with these amazing UV-sensitive beads! It's solar magic in action!Make bracelets, test the effectiveness of sunscreen, or experiment with color while you learn about the power of sunlight. Included is a science activity guide with lots of fun experiments with solar radiation and light.
