White paper is treated with fluorescent compounds to make it appear brighter. Historical documents that have been forged can sometimes be detected by placing them under a black light to see if they fluoresce; fluoresces have only been used in paper made after about 1950.
Club soda or tonic water contains quinine, a bitter-tasting fluorescent compound that glows blue-white under a black light.
Vitamins (specifically vitamin A, thiamine, niacin, and riboflavin) fluoresce strongly. A small piece of a vitamin B-12 tablet crushed and dissolved in vinegar glows a bright yellow under UV light.
Chlorophyll fluoresces with a blood red color. Grind spinach or swiss chard with ethanol and filter the resulting chlorophyll extract. Bright white light can be used to drive the fluorescence. Place the extract in a petri dish on top of an overhead projector lamp in a darkened room to get the full effect.
Antifreeze fluid contains additives that fluoresce. Investigators sometimes use black lights to look for antifreeze splashes on pavement and vehicles to reconstruct automobile accident scenes.
Laundry detergents contain fluoresces to make the whites "whiter than white". Detergent residues on white clothing causes it to glow blue-white under a black light. These fluoresces sometimes make white clothing appear blue in color photographs.
Dental enamel and whiteners also contain fluorescent compounds that fill in the blue part of the spectrum to prevent the enamel from appearing too yellow.
Postage stamps are printed with inks that contain fluorescent dyes.
Some liquids that glow under a black light include tonic water (due to quinine), some laundry detergents (containing optical brighteners), highlighter ink, and certain hand sanitizers. These substances contain molecules that absorb the ultraviolet (UV) light from the black light and re-emit it at a longer wavelength, creating a visible glow.

Does vinigar glow under a black light?
No, vinegar does not glow under a black light. The glow observed under a black light is typically due to fluorescent substances that react to the ultraviolet light emitted by the black light, which vinegar does not contain.
Do highlighters glow under a black light?
Yes, some highlighters contain fluorescent materials that can glow under a black light due to their ability to absorb and re-emit light at a different wavelength. It is important to note that not all highlighters will glow under a black light.
What color will gold glow under black light?
Gold typically does not glow under black light as it does not contain materials that fluoresce under ultraviolet light. If any glow is observed, it would likely come from impurities or contaminants in the gold.
Do fluorescent markers glow under a black light?
Yes, fluorescent markers contain substances that absorb ultraviolet light and re-emit it as visible light, causing them to glow under a black light.
Why does landuary detergent glow under a black light?
Laundry detergents often contain optical brighteners that fluoresce under ultraviolet light, such as a black light. These brighteners absorb UV light and re-emit it as visible blue light, making white clothes appear brighter and whiter. This is why laundry detergent may appear to glow under a black light.
Does vinigar glow under a black light?
No, vinegar does not glow under a black light. The glow observed under a black light is typically due to fluorescent substances that react to the ultraviolet light emitted by the black light, which vinegar does not contain.
Does any urine glow under a black light?
there is no kind of urine that will glow under a black light. Urine will glow green under a neon light, yet it is mainly unseeable with the naked eye without a neon light.
Do cats glow under a black light?
No.
Do highlighters glow under a black light?
Yes, some highlighters contain fluorescent materials that can glow under a black light due to their ability to absorb and re-emit light at a different wavelength. It is important to note that not all highlighters will glow under a black light.
Why does listerine glow under black light?
flouride
What color will gold glow under black light?
Gold typically does not glow under black light as it does not contain materials that fluoresce under ultraviolet light. If any glow is observed, it would likely come from impurities or contaminants in the gold.
Do pearls glow under a black light?
No, pearls typically do not glow under a black light. The fluorescence of pearls varies depending on the type and quality of the pearl, but they do not usually have the properties to fluoresce under UV light.
Why does ginger ale glow under black lights?
yes it does
Does a diamond glow white or black under a black light?
it will glow white, or more than likely, blue
