use a blue light instead of black light
well I think a good question would be, what is in the highlighter that gives off its glow
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.
Blacklight activated water is made with highlighter pigment and water...of course this may not be the answer you are looking for
you cut the highlighter in half and take out the felt tip and you put it in a small amount of water. After you put the felt tip in a small ,amount of water you put it under a black light and the water should glow. The best color to use is a yellow highlighter.
To make water appear to glow, fluorescent highlighter colors like neon yellow, green, or pink work best. The fluorescent dye in these colors emits a bright glow under UV light, creating the effect of glowing water. Remember to use caution and handle highlighter dyes with care when using them for this purpose.
This is a cool experiment for my fourth grader but she also needs to understand why the liquid glows.
Put radium in it. Just kidding please don't put radium in it, as it's radioactive and causes cancer. I would suggest putting glow-sticks or anything glow-in-the-dark in it that's safe to put in water. I've also heard of squeezing hi-lighter ink into the water
you dont
Yellow highlighters contain fluorescent pigments that absorb and then emit light at a longer wavelength, making them appear to glow under ultraviolet light. This phenomenon is known as fluorescence and is commonly used in highlighter inks to make them stand out.
AnswerSimple, you grab a bowl fill it half way with water crack open a highlighter (prefer yellow) squeeze the ink out of the highlighter into the bowl of water and turn on your black light and you have glow in the dark water.(:
Highlighter water contains fluorescent compounds that absorb ultraviolet light and re-emit visible light, creating a glowing effect under a black light. The fluorescent molecules in the highlighter water get excited by the UV light and emit a different color of light, giving off a glowing appearance.
To make glow sticks glow again, try placing them in hot water or in the freezer for a few minutes. This can help reactivate the chemicals inside the glow sticks and make them glow brighter.
