Why do things glow when they’re cold?

See the full video here:
Making Cold Light (Cryogenically Induced Phosphorescence)

[spaceaxolotl]

Slowly turning into Vsauce with that last part

[JTST]

Action Labs be like:

-> Try an experiment
-> Try the same experiment but involve liquid nitrogen somehow

[judesussman]

I love Cryogenically Induced Phosphorescence

[bakedatbeen]

So why do things glow in the dark?
"Yes"

[FatYoshi]

This guy is like the calmer, nicer, less chaotic version of Vsauce
Love them both

[kardoxfabricanus]

"I cast Cryo Light!!!"
that sounds like an awesome ability in a DnD class, where you freeze something so much that it starts glowing fluorescent lights.
thanks for the video it might actually inspire something interesting!

With the video loop i thought for a second that he'd actually tested it 😅

[genericalfishtycoon]

The first part of the video has a far more nefarious implication once you let the video play all the way through. lol Well done again sir.

You should turn off the auto-exposure mode in your camera and manually lock the exposure to the correct exposure for the florescent light level. Yeah, it'll be overexposed while the black light is on, but it will be possible to observe the smooth exponental decay curve of the florescence after the black light is turned off.

In this video the brightness is wildly fluctuating as your camera tries to adjust to the changing light conditions.

Don't leave us hanging, man. Time for a cold bath.

This collab has got to happen: action lab, veritasium, and vsauce

Edit: yknow what everybody wants everybody in apparently so this is the new best collab:
Action lab, veritasium, vsauce, Nile red, Steve mould, Mark Rober, 3 Blue 1 Brown, kurzgesagt, melodysheep, numberphile, asapSCIENCE, the backyard scientist, mrgreenguy, JaDropping science, physics girl, Bill Nye, sciencephile, slomo guys, the green Brothers, styropyro, organic chemistry tutor, Steven he, nardwar, smarter everyday, practical engineering, integza, electroBOOM, plasma channel, ididathing, applied science, Cody's lab, SciFun, linguist, T Folse nuclear, into the microcosmos, TKOR, crash course, Allen pan, thats all for now lmk who else to add.
This collab would be amazing, and to make it even better it has to be IRL

Remember to check back to see if I added your request, if it is during the us day time I'll get to it soon, but at night it will take more time

Edit: 2 months later I completely forgot I made this lol, truly do hope there is a collab with all the science yters tho

[theCidisIn]

You are one of my favorite science communicators. Thanks for all the awesome content!

If you took a glow in the dark toy, froze it in liquid nitrogen, charged it under a black light, and then shut the light off, would the toy glow brighter/longer?

[JakobMakesStuff]

If we consider a material that exhibits phosphorescence at cryogenic temperatures, one might study how these temperature conditions affect the quantum states of the electrons involved in phosphorescence. This could provide insights into how these electrons interact and overlap, potentially offering a model to observe phenomena like superposition or entanglement in a controlled environment.

You really are becoming powerful day by day

[IAmNumber]

WTF this makes me want to buy a black light and liquid nitrogen

[zacharyneely]

Cool video, I always wondered why fluorescent
Markers acted that way under certain lighting conditions. Thanks for sharing

[jodiecavinder]

My dear you already glow! And you show the most interesting videos!

[chocolate]

Last part sounds like something Nile Red would do

[minusskydiver]

Liquid nitrogen:
Makes magnets float
Makes objects glow
What else can it do?
