How quickly do the beads change when exposed to light?
and how quickly to they return to white once inside?
Thanks for the tip,
Scott

I have used ultraviolet sensitive beads with kids to demonstrate that the
sun gives off more than just visible light. While indoors, we string them
up on a lanyard or on a pipe cleaner (for a bracelet). Then we take them
outside and watch them change from clear to their various colors. I call
them sunburn detectors. The kids love them!

Does anyone have a suggestion for a simple, inexpensive way to
demonstrate, or better yet, let kids experiment with, the idea that
light consists of wavelengths beyond visible light, i.e. infrared?
