Since the naked eye can't see them, we are reliant on help to spot them, the black light make this possible.

The Science Behind The Item
UV lights reflect off of any given substance containing phosphor, something found in highlighters, fabrics, etc.
Keep in mind, though, it's not the purple light that is reacting with the phosphor - it's the invisible UV light.
Technically, UV light is radiation - it is a lower frequency wavelength than X-rays. So don't shine the light directly into your eyes!
