Brand new package of 1200 beads. The pictures go in order from direct sunlight to how they fade while indoors all the way to clear. Genuine Herbster Scientific brand beads are only sold by HWT Inc.

These were not as good as ones I had before from a science supply ...
The image shows the beads with bright colors and in the past I did buy a set that changed to bright colors and they were a little slow changing back to clear. This set was very pale when exposed to light some were pink and some purple but both pale and hard to see the difference. In my package, there were supposed to be 1200 beads (I did not count each my estimates are based on volume) I received 225 blue, 225 yellow, 225 purplish pink, and 300 pink - - - there were 225 that did NOT change color at all in light. These were not as good as ones I had before from a science supply source just easier to get hold of.

I liked these beads
I liked these beads, but some colors didn't show up in the light. The purple and pink show up well, love them. The blue and yellow didn't show up that good. half the bag was filled with the blue and yellow.

Science Fair
Bought these for an outdoor science fair on solar energy in Florida. Did the trick. Not very bright, though.

This is really cool. Even shows a light color on cloudy days
This is really cool. Even shows a light color on cloudy days. A good reminder for sunscreen even when the sun is not out.
