50 Assorted Beads &
1 Yard Beading Cord
(Enough for about 6 bracelets)
 These UV beads are an inexpensive fun way to teach physics and make the invisible become visible. These beads are truly Science Fun! Combine science, art and practicality. Our 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. Our 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. Children can make a simple bracelet  or other project with the cord provided in this kit which can function as a UV detector.  More cord is available by the yard.  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 five 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.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.
  • Beads measure 9mm in diameter.  Holes measure 3mm.
