12 Surprising things that glow under UV light | A blacklight experiment

[@konkandesi]

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.

[@justimagine2403]

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!

[@hardcandy921]

Scorpions too!

A whole lot even when you don't actually expect. I have had too much fun with my filtered Nichia NVSU233A blacklight flashlight I put together years ago.

[@Dr_Mario2007]

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. 🤷

So that's why they used it in the Splatoon campaign

The music is very annoying.

[@GeekHoodlum]

Ha ha. It kinda is.. won't be using this track again👍🏻

[@Davineff1]

@@GeekHoodlum no I loved it! there will always be someone who says that. not looking forward to silent videos

[@dinizen]

@@Davineff1 im in the ''very annoying'' camp.

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

[@GeekHoodlum]

No worries 👍🏻

I just realized sticky notes also glow

I used to have psychedelic poster that would glow with a black light. If I orint images of psychedlic posters on sturdy foamboard, will they also glow with a black light,?

[@lovelylipbonesouwwwwwwwolv2198]

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.

[@GeekHoodlum]

Great tip. I'll have to give that a go!👂🏻

[@ginkumpow3726]

I've heard to never take a blacklight into a motel room.

Beer glows engine coolant green. try banana spots also.

[@maddenborntowin7273]

We can also use a invisible light pen as a black light

[@hotquebec]

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

[@0utcast]

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.

[@Grateful.For.Everything]

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.

[@hadleymanmusic]

It rather phosfloureses

[@djzrobzombie2813]

Dislike for the crack head music

Fair call. I won't be using this one again 👍🏻

[@Mor2gain_760]

It sounded fine to me...

Brooo I have that same flashlight

Scorpions glow under uv

[@bi_panic_2874]

A THC cartridge

[@michaelc3977]

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

[@0utcast]

its probably a cheap 395nm light he needs to get a 365 nm source. 365 doesnt put out much in the visible spectrum and is the wavelength you want for maximum fluorescence. a 365nm led source is ideal

[@Spacecookie-]

Spoilers: not as surprising as the title might suggest.

[@delavan9141]

Recommend sound off.

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

[@niveoIe]

Theres literally a playback speed function..

[@punktalley]

I know I only got 4 hours, 59 minutes and 47 seconds to watch this crap.
