    Default What is the glow-in-the-darkingest glow-in-the-dark material?

    Related question: what is the blacklight-fluorescingest blacklight-fluorescent material? Hippies and partygoers, please advise?

    Caveat: this information is intended for a Halloween decoration project, so any recommended material or product should ideally NOT be dangerously radioactive, insanely toxic, prohibitively expensive such that it is typically sold in microgram units, or purchasable solely through government contract or the East Asian black market.

    I've got my black light bulb and posters in the basement but for glowing fluorescent material those chemflour rods are the brightest.

    Semen.

    But assuming you don't have access to mass quantities of semen, laundry detergent works really well, is easy to work with (just get a paintbrush and paint it where you want it) and it's cheap.

    Based on my night club based experiances: The glob of mayo that fell on your shirt that you think you wiped all the way off. It didn't.

    A quick search shows:

    White Paper
    White paper is treated with fluorescent compounds to help it appear brighter and therefore whiter. Sometimes forgery of historical documents can be detected by placing them under a black light to see whether or not they fluoresce. White paper made post-1950 contains fluorescent chemicals while older paper doesn't.

    Petroleum Jelly
    Petroleum jelly, such as Vaseline, glows a bright blue color under a fluorescent light.

    Club Soda or Tonic Water
    The bitter flavoring of tonic water is due to the presence of quinine, which glows blue-white when placed under a black light.

    Body Fluids
    Many body fluids contain fluorescent molecules. Forensic scientists use ultraviolet lights at crime scenes to find blood, urine, or semen (all fluorescent).

    Vitamins
    Vitamin A and the B vitamins thiamine, niacin, and riboflavin are strongly fluorescent. Try crushing a vitamin B-12 tablet and dissolving it in vinegar. The solution will glow bright yellow under under a black light.

    Chlorophyll
    Chlorophyll makes plants green, but it fluoresces a blood red color. Grind some spinach or swiss chard in a small amount of alcohol (e.g., vodka or everclear) and pour it through a coffee filter to get chlorophyll extract (you keep the part that stays on the filter, not the liquid). You can see the red glow using a black light or even a strong fluorescent bulb, such as an overhead projector lamp, which (you guessed it) gives off ultraviolet light.

    Antifreeze
    Manufacturers purposely include fluorescent additives in antifreeze fluid so that black lights can be used to find antifreeze splashes to help invesitagors reconstruct automobile accident scenes.

    Laundry Detergents
    Some of the whiteners in detergent work by making your clothing a bit fluorescent. Even though clothing is rinsed after washing, residues on white clothing cause it to glow bluish-white under a black light. Blueing agents and softening agents often contain fluorescent dyes, too. The presence of these molecules sometimes causes white clothing to appear blue in photographs.

    Other Cleaners
    Examples of other types of cleaners that glow under black light include Irish Spring™ soap and Mr. Clean™.

    Emperor Scorpion
    The emperor scorpion normally is dark brown or black, but it glows a bright blue-green when exposed to black light.

    Tooth Whiteners
    Whiteners and some enamels contain compounds that glow blue to keep teeth from appearing yellow.

    Postage Stamps
    Stamps are printed with inks that contain fluorescent dyes. However, the US stamps that I checked (printed 2008) did not glow.

    Jellyfish
    If you have a jellyfish handy, see what it looks like under a black light in a darkened room. Some of the proteins within a jellyfish are intensely fluorescent.

    Some Minerals and Gems
    Fluorescent rocks include fluorite, calcite, gypsum, ruby, talc, opal, agate, quartz, and amber. Minerals and gemstones are most commonly made fluorescent or phosphorescent due to the presence of impurities. The Hope Diamond, which is blue, phosphoresces red for several seconds after exposure to shortwave ultraviolet light.

    Banana Spots
    Who knew? Shine a black light on a ripe banana with spots. Check out the area around the spots.
    Hell, if I didn't do things just because they made me feel a bit ridiculous, I wouldn't have much of a social life. - Santo Rugger.

    Thank you muchly for that comprehensive review of the topic at hand, Cluricaun. I figure I can make my holiday decoration project out of emperor scorpions, bodily fluids, and the Hope Diamond.

    Now I have to let a banana go brown in order to see the spots glow. Fortunately for me, this is the inevitable fate of every single banana I buy. I guess for maximum effect you should only smoke the glowing parts?
