Solar Bead, uv bead colour change

Product Description

• These 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 *0,**0 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.

The amazing color changing beads due to the sunlightSolar Beads contain photochromatic dyes that react to UV light and cause the normally white beads to change into vibrant colors when exposed to the sun or UV emitting black light

Then, when removed from sunlight, the beads revert back to white. Solar Beads can also be used to perform a number of science experiments: Find out what happens to your beads when they wear sunscreen, sit behind your sunglasses, are underwater or on a cloudy day. What keeps the beads white will prevent your skin from being burned
