Glow in the dark things were not invented because you can't invent something that was already existing! Someone did discover it though: Hennig Brand. He was a German scientist (we would call him a scientist- in those days, he was called an alchemist) and he found the substance phosphors, which all glow in the dark things contain. Brand saw that the phosphors, which reacts to a great extent, glowed when it was combined with oxygen ("glow" in the dark). This is the substance that causes glow in the dark items like clothing, toys and bracelets to glow!!
Hope this was useful!!!The original glow in the dark was made from a toxic material called Radium. My Uncle Takeishi Osaka of Tokyo Japan invented the modern version of glow in the dark. You oldsters may remember that glow in the dark once only came in that off green sort of color. He also invented a way of ionizing that allowed pigment to stick to the chemical allowing the various colors we now have. Uncle Takeishi died in the late 1980's. He dedicated his life to helping the blind and this was one of his achievements in that area.
When things that are supposed to glow in the dark don't, it is usually because they were not exposed to other sources of light. For example, glow stars only glow if the light in the room they decorate has been on for sometime, in a kind of absorbtion process. Without previous contact with a light source they can't glow.

A dead crab claw would not naturally glow in the dark. However, if the claw were to be coated with a phosphorescent or bioluminescent substance, such as certain chemicals or organisms, it could potentially emit a faint glow.
No, glow-in-the-dark items, including splat glob, need to be charged under direct light to emit a glowing effect in the dark. The glow will fade over time as the stored light energy diminishes.
To make glow-in-the-dark caps, you can purchase glow-in-the-dark paint or stickers designed for fabric. Apply the paint or stickers to the caps following the product instructions, usually involving exposure to light before glowing in the dark. Ensure the caps are clean and dry before applying the glow material for best results.
Glow-in-the-dark paint was invented by Bob Switzer and Joe Switzer in the 1930s. They were looking for a way to make bicycle lights more visible at night and discovered a luminescent paint that glowed in the dark after being exposed to light.
