OK what i meant was. You hear about something being UV Reactive. How do you make it glow? Blacklight? A UV light? What does a UV light look like I've never seen one?
Yes, UV/blacklight CCFLs agitate the flourescent or phosphorescent molecules in UV reactive items to the point that they emit their own wavelengths of light. Phosphorous can be found many places, such as the bleaches or whiteners in typing paper, bacteria, and a number of bodily fluids in all manner of living things.
Scorpions for example are nearly impossible to find at night in the desert without a blacklight.
