Product Overview
Ages: 6+


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 short 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.
