Editing Glowing Bubbles (section)

== Why This Works ==

''Fluorescence'' is when something can absorb high energy light, and then releases lower energy light. Black lights give out violet light, which has a lot of energy to it. Fluorescent materials, such as the bubble solution, can absorb the violet light, which gives them a lot of energy. The extra energy they give out as light, but the light they give out will have less energy, which is why they have a blue glow. The term fluorescence comes from the element Fluorine, which glows brightly under a black light. Fluorescence isn't a reaction in a material, so it isn't something that will fade away after a while. This is why the splatter of bubble solution continues to glow on the tarp! Fluorescence is instead a property of a material, so if something is fluorescent then it will always glow under a black light!
