Hypersphaera phosphori

Hypersphaera phosphori
Glow-in-the-Dark Superball

These translucent Superballs contain a substance that radiates visible light after being energized.  These "phosphors" - often Zinc Sulfide or Strontium Aluminate - will provide a persistent visible glow when they are moved from light into darkness.  The length of luminescence and brightness depends on the strength of the energizing light source and duration of exposure.  The light (and the balls) and general green, but can vary depending on the pigment of the rubber in which it is housed.  Occasionally, a printed pattern will be applied or the phosphors can be mixed into a portion of the ball creating varied phosphorescence.
