Who doesn't love glow-in-the-dark Halloween costumes, stickers, or glow sticks? Many bugs glow in the dark, too. Unlike glow toys, these bugs make their own light. These bugs are bioluminescent (by-oh-lew-muh-NESS-ent). Chemicals in their bodies combine to make them shine. Although bioluminescent animals light up, they don't give off heat like a light bulb does. Fireflies are the most common glow-in-the-dark insects. They light up to communicate with each other as they look for a mate.
Because there are certain chemicals on them that collect light, then slowly give it back off, but you really only see it when it's dark.
Glow toys are those which give off a light. There are many types of glow toys including glow sticks, glowing cars and even glowing crayons which children find really interesting.
There are many retailers that sell glow worm toys online some include walmart.com, kmart.com, toysrus.com, amazon.com and ebay.com. You can also find glow worm toys in public retailers such as toys r us, walmart, and kmart.
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.
Glow-in-the-dark eggs typically contain phosphorescent materials that absorb and store light energy. When exposed to a light source, these materials become energized and, upon being taken out of the light, slowly release that energy as visible light, creating a glow. The duration and intensity of the glow depend on the specific compounds used and their properties. This phenomenon is commonly used in toys and decorations to create a fun, luminous effect in the dark.
