Ground up Vitamin B Tablets

When one ground up pill is added to water, it glows a sickly yellow-green. Really cool

Cup Noodles

the popular Cup Noodles definitely glows under black light. The residue on the sides of the styrafoam glows, and if you pour the broth into a shallow bowl that will glow too. Yuck
—Guest Angela

Milk Money

Pour yourself a tall glass of milk and break out the black light. Milk glows brightly, with a sickly yellow tinge... looking a bit like eggnog. Modern US paper currency has dye in the security strips that glows (excluding $1 & $2 bills). 5 dollar bills seem to "bleed" their UV dye moreso than the rest.

laundry detergent

I put a bit in clear bottles and filled them the rest of the way with water.

Most state DL's and ID's

Many states in the USA provide hidden images or words in their driver's license and ID's for authenticity when checked at bars or clubs. Many major credit cards will also have hidden images or letters, too.

How can you forget drugs?

Cocaine glows under a black light. That is how they can quickly tell it from sugar and baking powder!

Highlighters, especially yellow ones, glow under black light. This can be especially fun for body art, because the yellow highlighter often doesn't show up on skin in regular lighting-- only under the black light.

Crt tv screens and monitors

I bought a small led black light from the pet store.I can use it to draw words on my tv screen in the dark ... The screen remains lit where I exposed it to the light for nearly a minute.

Glowing Teeth

A lot of people's teeth glow under black light. I bet it's because of whitening toothpaste, unless it's the fluoride compound that glows!
