UV Beads (1000)

Product Code: SE-7729


Shining an ultraviolet flashlight (such as the UV Flashlight) on these UV-sensitive beads causes them to change color.

UV-sensitive beads are white when indoors but change color instantly when exposed to UV radiation. These beads help make students aware of UV radiation. Students can explore how much UV there is on a cloudy day or how much UV is blocked by car windows. Want to quantify your results? The Wireless Light Sensor can measure UVA, UVB, and UV Index for a more thorough investigation.

Each bead is created with a pigment that changes color as the ultraviolet energy is absorbed. When the UV radiation is removed, the beads will return to their pale white color. This process can be repeated many thousands of times. Each package includes 1000 beads.
