The other day I was out shopping. Right now it's Back To School Sale time, so things like crayons and colored pencils and markers are all on sale. I picked up three packages of fine line Crayola markers for Pennsic Heralds Point, which cost a total of two bucks. But while I was there, I looked at the colors offered in the "Bright Colors" collection. Among the offerings are "Infra Red" and "Ultra Violet".

All marketing hype, of course. But the geek in me wants to see Crayola sell markers that are *truly* colored infrared and ultraviolet. *Those* would be cool to have.

Thanks!

Now all I must do is convince Crayola to make a marker with no color except that... and likewise a marker whose dyes only absorb IR.

It's funny, I learned a lot about UV radiation, but very little about IR. You could probably do colorless and IR-radiating by using 2 colorless chemicals that create an exothermic reaction.
