Reflective Sticker

Sample: A highly reflective sticker of the highway variety.
Source: Box of similar stickers, contributed by Ben Zank.

If you've ever driven on certain roads in the US (sorry Canadians, but I have no idea if similar things are used up there), you might have noticed that the labels on certain telephone poles or electrical boxes seemed to appear unnaturally bright and reflective.

To acheive this effect, tiny glass spheres are added to the yellow pigment put on the sticker. Each sphere acts like a tiny lens, taking in light, bouncing it off the pigment, and reflecting it back out, at almost the same angle it came in at. This means maximum brightness to the observer. A similar effect can be seen on a dew-covered lawn in the late morning. Called Heiligenschein (I hope I spelled that right), this has the effect of making it look like an angelic halo of light surrounds the head of your shadow.

Thank you! I am partial to the cellphone ones myself. I suppose destroying things (accidentally, of course) works out for the best occasionally.
