yes they are
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.
A good hypothesis for glow in the dark water could be: "If a luminescent material is added to water, then the water will glow in the dark due to the light emitted by the luminescent material when exposed to darkness."
Highlighter ink does not glow in the dark on its own. To make water glow in the dark, you would need to use a fluorescent or phosphorescent pigment designed for that purpose. These pigments are usually powders that need to be mixed with water in specific quantities and then exposed to light to charge up before they will glow in the dark.
Yes it can be made to glow if you use tonic water. Use half tonic water and half water and our jello will glow!
Not that I know of go look in wal-mart
well I think a good question would be, what is in the highlighter that gives off its glow
No, Glow in the Dark Silly Bandz are neat because the glow in the dark!
I'm not sure if they make glow in the dark, but they make neon and if that is not good enough, you can buy glow in the dark fabric paint and turn them glow in the dark by yourself. they will be your custom designed glow in the dark converse if you do it by yourself
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.
