Description
Shining an ultraviolet flashlight on 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 make students aware of UV radiation. Students can explore how much UV there is on a cloudy day and how much UV is blocked by car windows.
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.
