What is a liquid that glows under a blacklight?

Question

Preferably one that is cheap and easy to obtain and won't stain fabrics. I'm gonna put it in a water gun and paint my basement walls.

Answer 1

One of the coolest things we did a few years back was to take those glow in the dark necklaces that they sell at concerts and fairs, poke a couple of pin holes in them, then swing them around the room. When we turned on the black light, everything was covered in little dots that glowed. It looked just like you were standing in the middle of the galaxy. Of course they only lasted a few hours, but it was pretty cool.

Answer 2

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 Sometimes forgery of historical documents can be detected by placing them under a black light to see whether or not they fluoresce.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.

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 purposedly 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.

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.

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.

Answer 3

Buy some glow in the dark paint. They have it at Hobby Lobby and Michael's. It is acrylic paint and is fairly inexpensive. They have several different colors.
