Experiment with your Mini Black Light key chain for a personal fluorescent show! "Black Light" is really ultra-violet light, which is naturally present as a component in sunlight. Ultra-violet wavelengths are very long with a very high frequency, and can be used to detect florescent material that would remain invisible under normal conditions. When you shine ultra-violet light on fluorescent material, it lights up with a beautiful bluish-green luminescence. Great for science experiments with using different lengths of light waves, or as an interesting addition to your next science fair project. Try using the black light with our special Invisible Writer (WINV-100) and leave secret messages that can only be revealed with your Mini Black Light!
