There are some oddball white fluorescent lamps that have weird phosphor formulas that causes it to light up weird green or reddish pink. And if you got some synthetic ruby (some smoke shops obviously got terpene pearls there that are ruby and much easier to get), put it under the blacklight, they glow red - fake ruby don't glow. There was one thing that actually surprised me, the Osram Powerball ceramic metal halide bulb, that I decided to check to see if it got UV block dopants added to the quartz envelope - I didn't expect the salts to glow hot pink within when I shine blacklight straight at the ceramic arc tube. Also, don't forget, my favorite; peanut butter, they have persistent phosphorescence effects that lasts for a second or two, you need to be in a dark room to see it. I have a filtered Nichia NVSU233A blacklight flashlight I put together years ago, so I had too much fun with it. 🤷

Your bathroom, paper, your toothpaste, clothes especially white tshirts. Your fingernails. Uranium glass. Certain cd and dvd cases. Construction paper. Book bindings. LED light filaments. And many more!

Ok olive glows red

My dude forgot credit and debit cards

I didn't think my crumpet would glow. Yet here we are 😂

They played this kind of music in the Hanoi hilton...

this was a pretty cool video

I just realized sticky notes also glow

not all of these things are fluorescent. only those things that glow BRIGHTLY like white or neon colors are actually fluorescent. the things that glow dimly are either not very or are just reflecting the UV light because some of the light emitted is visible.

I really wanna get this lol but I need help, terpene pearls are being used as synthetic ruby and they actually light up under UV but fake ones don’t light up? Something like that, I’m close… I can feel it lol.

Beer glows engine coolant green. try banana spots also.

Dried urine will glow under a blacklight. Useful in detecting pet accidents as well as mice or rats activity. You can use the blacklight to see how well you cleaned your toilet.

GH, good video. Do you mind if I use just a few seconds, for an educational video i'm currently shooting? I'm happy to give credit

Some halogen bulbs also glow under a blacklight by the way.

Weed vape cartridges really glow under u.v. at least the distillates do anyways.

It’s ok if you turnoff-the background noise.

Idk why u have such less subs u deseve more

I have a uv light and wanted to know what things could be glowing under it. Also earwax can glow under uv light, dont ask how I know this.

It rather phosfloureses

The music is very annoying.

A THC cartridge

Your sphincter glows if you drink enough florescent paint

Spoilers: not as surprising as the title might suggest.

Banana that are over ripe look like mahi mahi

BTW. your cheap LED black light is naff. So much ambient light. Buy florescent tubes

Tldw : any thing organic glows ...

Dislike for the crack head music

Squizitzi that’s Italian for yummy 😎

Yeh the music was not good

I must say im slightly dissapointed... I was looking for the money shot!

Mureen

Urine , seamen , punani juice

Bad music

Try soy sauce lol

Milk

you know what else glows under black light? Semen… Lots and lots of semen.

This is dumb.

This was pretty boring just seeing if random shit glows or not.

Do the people who make these videos think we have 5 hours to watch their crap? Maybe you have nothing better to do but these videos are too long and slow, just not worth it
