AWESOME FLUORESCENCE THERMOCHROMISM

[Corkoth55]

i want to minor in chemistry and from hearing some of the names you used... i have a long way to go...

[joshuachingto]

hey sir I need a project I need to make a tesla coil can you teach me how to make one i'll subscribe every movies you have if you teach me how to do that

[dmasta46]

good use for it? tron costume...

[Iniss132]

Is this similar to the color changing attributes they use in the paints or plastics of toys that change color when heated or cooled?

[MrOpensaysme123]

i have no idea what any of the things you say. its like,

"the molicules in the sodium oxide are disolving with the ectro tonium nitrate.

i dont really listen. its just fun to watch.

[parkerstoybox]

is that how those flat nightlights work

[miesrah12]

hmmm a Tempatuer detector for the freezer food industry, but we need a diffrent formula

[AshuraK242]

Would it be possible to use this in measuring devices, designed to detect extreme temperatures?

[Danielp098]

Can you make a video on something like a glow stick that lasts for a week, but also where to get the ingredients and how to make it? :)

[terminator6267]

Wow....I bet the antartic explorers use that chemical in special glow sticks to glow MUCH LONGER with the infinite cold that the antartic provides....BRRRR!

[bsboy20]

@Nurdrage, i did this in my HS chem class your an inspiration thank you!

[PistenBoy]

It could be used in space to determine if the temperature of an object is heated or at 3 K

[ajuk1]

A glowing thermometer that changes colour depending on the temperature.

[metalfacesolid]

9 people mist the like button

[ajuk1]

@metalfacesolid Mist... mist fucking mist, really?

[paintballwis]

It could be used for military signaling, just have a small heater and your able to make a bright red/orange/yellow/ glow that might be seen by helicopters/planes, but could be hidden if you are under fire. I FOUND A USE :D

[rorrt]

It could be used for some sort of cool Hypercolour t shirts!

Although that was already done in the 90s.

[bsboy20]

@rorrt you'd have to be in ultra violet light and be dipped in liquid nitrogen... ;/

[rorrt]

@bsboy20

That is a price worth paying for a tee shirt to change from blue, to green.

[ACDCNORWAY2]

COOOL!

[randombloke82]

@thabomba378: the air you breathe is over 70% nitrogen already. Unless you stick your head in the bucket or try to huff the vapour you should me OK.

[randombloke82]

@thabomba378: the air you breathe is over 70% nitrogen already. Unless you stick your head in the bucket and take a deep bre

[jazminedwards]

his videos wouldnt be the same if we could hear his normal voice

[jigglypuff1337]

How long does liquid nitrogen outside some freezer and how do you store it? Shouldn't it all turn into gas or something?

[shogoonn]

@jigglypuff1337 LN2 should be kept in a dewar flask. It will turn into gas eventually. The rate of evaporation depends on surface area and insulation quality. The more you have, the longer you can store it (lower surface area to volume ratio). In a flask like the one in this video it would last for a couple of hours (like 8, maybe 12). 1 litre spherical flask with narrow neck would do for about 2 days (until LN2 evaporates completely). 40 liter dewar will keep nitrogen liquid for about a month.

[jigglypuff1337]

@shogoonn wow that's pretty long, thanks!

[natnetsam]

where do you get liquid nitrogen

[bsboy20]

@natnetsam logistically its difficult unless you have good reasons for its use. which you don't. but if your desperate go to your doctors office to get a wart removed and bring a thermos after you get your war frozen beg the doctor to let you poor the liquid nitrogen into your thermos if they are cool enough they'll let you. my doctor let me fuck around with it one time shes pretty nifty

[UTubeisSHIT523441]

beautifull

[noreason2701]

Now I feel retarded. I should have remembered that...

[noreason2701]

@NurdRage

So why do those little $0.10 glow sticks people hand out at say.. independence day fireworks shows pretty much stop when you put them in a freezer? Are they an exception to the generalization you described in the video?

[NurdRage]

@noreason2701 Glow sticks are not exceptions, they're completely different things. This video is on fluorescence, a glow stick works on chemiluminescence.

[xXxmidgexXx]

i wowed 

[dA55assin117]

Thats sick!!

[MrSkinnyBill]

This may be a difficult question, but how much nitrogen gas is that liquid equivalent to? I am of course referring to the pressure etc of nitrogen in the air.

Would it fill a room, a house or what?

[bytessoftware]

@nurdrage even though I love science, you make my brain hurt.

[SepradistPhantom]

Dr. N. Butyl Lithium? Did you change your name by deed poll?

[augustovera85]

eres genial amigo!! muchos saludos... you should talk about chametrails!!

[SaviourV]

That's the first time I've seen you use ALL CAPS in a vid, NurdRage. This must be a significant find indeed. Well....as good as it gets, I guess, until someone manages to make something useful out of this find. Maybe a temperature-sensitive glow-stick, useful in extremely hot or cold conditions, in dark areas, perhaps? I dunno.

[zomgt3hpoison]

I must say that this experiment is a thousand times more impressive in person than on youtube. I have three questions, though.

Is the solution safe to store in a closed container for a short while (a week at most)?

I got a much more bright green after evaporation when chilled than without heating. I also got a pink color, rather than blue, after heating once and chilling: i54.tinypic. com/9vimjc.jpg . Should I worry about either of these?

Finally, is it ok to see small spots on the paper?

[PrinceNomii]

hey, nurd rage! thanks for this awesome vid

[thabomba378]

do u need a fume hood for liquid nitrogen?

[armiks22]

make some fulminated mercury please :)

[BhudhaLovesBudlight]

....uhhh so what exactly do you do for a living? just curious

[luisdemasiado]

will it shine forever?

[varadjoshi41]

where do you got copper iodide or how do you make it?

[simpsoncheat]

How long does the glow last on the trispyridine copper iodide??

[TakronRust]

Would using europium iodide glow more? Since europium is used in a lot of glow compounds?

[Zanragnar]

Can this product be used as a dye for glowsticks?

[fleemonstay]

I quite liked the blue glow

[superstarmeagher]

...use the fluorescent stuff on undercover cop cars .... so there paint can change when they are chasing someone...

[GohanTheHokage]

Ugh im in high school and i dont even do these stuff

[Hazel0283]

is this how they make glow stick?!

[hawkinfilmz]

how about a homemade thermometer? or a prank by puting some on furniture and when they use a black light tell try to clean it and get mad :D

[SonEriccs]

what can the substance stick to? once dried can it still produce light with a uv lamp? i think it would be great as an equipment thermal indicator. just shine a uv lamp over it while its dark or whatnot and it shows a color. if i knew a bit more about the substance i could probably think of more applications.

[cheetawolf]

so what happens if i stick a glowstick in liquid nitrogen?

[Yeuxvert]

@cheetawolf  Try it!

[cheetawolf]

@Yeuxvert do you know where i can get liquid nitrogen in Michigan?

[shinigami815]

does the fluorescence slowly weaken over time?

[aaappp51]

Where do you get pyridine?:)

[NurdRage]

@aaappp51 i got mine from a company called "Sigma Aldrich"

[TheScienceiscool]

@NurdRage Yet another amazing video! do you think it may be possible for you to show the preparation of n butyllithium? I love organometallic chemistry and this sounds like an interesting compound (also its too toxic to make at school)

[bsboy20]

@NurdRage i love you.... and im a guy just to let you know :)

[TheRolemodel1337]

@NurdRage it smells like tomatosauce for instant spaghettis :p

[PattyMMelt]

0:07

Why would a fume hood be wearing gloves??

[Shark781227]

@PattyMMelt nice one xD

[MoonBurgle2]

this was fun to watch, but I found hte voie change a bit hard to listen to and distracted from the over all presentation.

[UTubeisSHIT523441]

best video ever. Thank you NurdRage.

[TheLasersRule]

@adracamas use that as a light lol

[MasterPenguin777]

why do you mask your voice...

[zbret]

8 People can't see colors :)

[Algonkin1964]

I'm not sure if you are the one implementing ads in your videos but I don't care much for them. They are useless and annoying.

[JaiNobesIsARat]

@Algonkin1964 Nobody likes them, but he's getting paid for them. I'm willing to put up with them if it means NurdRage gets a bit more pocketmoney and therefore more money to spend on videos and more incentive to make more.

Search for the YouTube partnership programme. Anyone can do it, you just need a popular enough video.

[Algonkin1964]

@JaiNobesIsARat Yeah I know... they're just so annoying. They're on almost every YouTube videos now...more and more. Cheers!

[razalin]

Nurdrage, I'm pretty confident that if you were a Science teacher at a school, you would have a 100% attendance roll, EVERYDAY. I've only just found your channel and i'm very impressed thus far, keep up the great work.

[ichbinned2]

@razalin i hope he doesnt use this voice during class tho

[xja85mac]

Someone invented a similar application: bracelets that fluoresce after cooling them in a freezer: I was surprised how something can fluoresce if you strip down its energy, but quantum mechanics always surprise us.

Nice video.

[C00lman555]

you sound like you use a voice synth... lol

[jackcat12345]

probably my all-time favorite video. I have taken the time to watch all of your videos!

[fruitcake117]

science is so awesome

[Wanton110]

Could be used to coat arctic exploration clothes.. When it gets below a dangerous temperature the glow will change, especially useful if it's during the perpetual night cycle.

[Jashomartin]

inhale Sulfur Hexafluoride :D your voice would be so deep!!

[spotlightman1234]

@Jashomartin it would be below the human ear's hearing range lol.

[spotlightman1234]

@Jashomartin it would be below the human ear's hearing range.

[KellyAkhil3]

Ur the Greatest scientist I've ever known.

[GodofSpanaway]

awesome, I love chemiluminescence experiments.

[instazx2]

This has applications for public health and safety, if there are room-temperature transitions and colors that don't require UV. Showerheads could turn a warning color if the water temperature is above a scalding limit (120F). Roofs could be painted such that they turn white above 90F and darker shades otherwise.

On things that do require UV, I could see it being useful for USDA inspectors. They can walk around with a UV wand and spot-check that food preparation surfaces are the correct temp.

[gundown22]

Beautiful



[Deathscythe767]

Neat.

[thegodofchemistry]

dear nurdrage have you ever peed in a destilation setup and distilld it

[spotlightman1234]

@thegodofchemistry what the...? this has to get the top comment.

[thegodofchemistry]

@spotlightman1234 what?



[91770158]

My counter does not allow the chemicals i need for most experiments: Acetic anhydride also known as Acetic oxide Acetone also known as 2-Propanone or Dimethyl ketone Anthranilic acid also known as o-Aminobenzoic acid Ethyl ether also known as Ether or Diethyl ether or Ethyl oxide or Diethyl oxide or Ethoxyethane or 1, 1'-Oxybisethane Hydrochloric acid Methyl ethyl ketone also known as 2-Butanone Phenylacetic acid Piperidine Potassium permanganate Sulphuric acid Toluene

[1zacster]

Hey how much does liquid helium cost compared to nitrogen? I wanted to try and break the world record for the highest cow clock rate(8.4GHz)

[beliel122]

Oh nurdrage, I've missed your videos.

[lizard75722]

that  was awsome

[virtuosoikingpin]

I watch your videos with all the awesome equipment, awesome reactions, and love chemistry. I go to lab and have a very limited time to do everything, get a taste of Murphy's law, then keep getting percent errors of like 30-50%. I don't think I should be anywhere near a laboratory, I'm much too clumsy. I'm just waiting for the day when I grab a wrong chemical and kill everyone in lab o.O.

[quackerzdb]

This was awesome!

[Ratysz]

The best demonstration of the effect out there: well presented, thoroughly narrated and full of pointers to further info. Thanks a ton for sharing!

[Mettrone]

NurdRage can you show me how to make a nuclear reactor, for safety reasons so I don't do it while experimenting with all the necessarily materials. thank you

[varad5454]

whts the price of copper iodide? --- Sent From NurdRage's AppRats (Facebook App)!

[sciencetestsubject]

@varad5454 It's really easy to make yourself, only need copper(II)sulfate (root killer), an iodine salt, water and a filter.

when both are dissolved in water it will react to copper(I)iodide and Iodine

copper(I)Iodide is extremely insoluble in water, so filter it off and dry it.

pyridine however is slightly harder to get.

[herropreasepaur123]

Just wondering, do you use a voice modulator to disguise your voice or is what we hear your actual voice, if so then i wish to switch my vocal cords with yours.

[h2soccergod]

this is so cool. wish my science teachers in middle school did this to attract kids to science

[thegodofchemistry]

dear nurdrage can you shoe how to make acetic acid or a test for every gases please thumps up so nurdrage can see this i miss the old nurdrage

[airbornmtnbiker]

@NurdRage

Is that your actual voice or are you using something to change your voice? Awesome video!

[TSSPhotonPhysicsClub]

Awesome Vid!! Great Contentl Check out our Channel!!

[TrueHunter117]

where can i get liquid nitrogen?

[sugarspiceandallthat]

Why is science so interesting and amusing but yet confusing and frustrating???? Haha. Chemistry you're killing me

[bryakorn1]

great!!! nice!



[an50331]

i know this is a family show but a bit more explanation is warranted, now i have to surf around wikipedia, this nurd is not happy!

[Sw1p3r99]

what the CRAP!!!!!

[xxxrobert123xxx]

Here's an idea, drink a few gallons then have a pool party. Your friends will flip when they see what happens when you go from the pool to the hot tub and back... assuming that you've figured out how to magically counter act any and all adverse effects it would have on your body.

[HuskyWolfy]

this must be what konami thought of for that key card thing in metal gear solid 1

[drummerb0y313]

extremly interesting 

[pumkinvine]

Your videos are always interesting

[Orical001]

so thats how you make a yellow light saber...

[MrJurisevic]

my mind is full of fuck

[blinx12ss]

Science Bitch!

[managrey]

DO YOU WANNA PLAY A GAME...

[managrey]

DO YOU WANNA PLAY A GAME...

[TheCommiSpy]

i have no idea what hes talking about but i like the pretty colors

[Stonehawk]

hey, nurd rage! thanks for this awesome vid. It was a fascinating watch. I was wondering though... if you could maybe answer a hypothetical question in a video sometime: What if you suddenly woke up in 12th century europe, and somehow discovered that the only way to get back home would be to chemically concoct the most powerful explosive you can, given the materials available (to alchemists for instance) at that time. This is for another nerdy pursuit: a D20 campaign :D

[NurdRage]

@Stonehawk Depends on how much time you have. Purely hypothetically, if you had sufficient time (say 10 years) you could concoct *ANY* explosive we have now.

Because we *still* don't have anything now that we didn't already have in the 12th century. All the elements, all the chemicals and all the minerals have not changed. What we have now in our modern time is the scientific understanding to use it.

[JaiNobesIsARat]

@NurdRage That was a great answer.

[liberator279]

why do you change your voice?

come one, we're all nerds here :p

[lazylazyass]

Damn it, now I have to find SuperSuperboy5's comment

[Scuzzz]

didn't know jigsaw was a science pro

[NurdRage]

@Scuzzz I am not jigsaw.... i am his goofy cousin hacksaw. :)

[ArceusLight23]

@NurdRage lol and im his brother bonesaw -laughs-dude where did you get liquid nitrogen

[OhNoNotMyPenis]

@NurdRage

just gotta ask

do you edit your voice in anyway?

[royfireball1]

@OhNoNotMyPenis i think he does

[rushianokun]

Hail to you! Thanks for such an amazing vid!!!!!!  Keep up the cool stuff!

[omullick]

use that youtube muny to buy urself a new hotplate

[NurdRage]

@omullick youtube actually doesn't pay very much. But anyway, "if it's not broken don't fix it."

[omullick]

@NurdRage touche good sir

[greenpogo]

@NurdRage i think that hot plate is the greatest - it looks well used

[k0namiman]

@omullick I think he spent it all on LN2 which is ultimately more interesting than a shiny hotplate. ANyway, NurdRage, is this related in any way to the 'hypercolor' dyes used on expensive thermally reactive shirts in the 90s and color-changing dyes in toys?

[xkingxx00]

yunonurdrage?

[Palizasadomicilio]

Your La... I say, garage must smell like rotten calamari! Nice to see more videos from you!

[NurdRage]

@Palizasadomicilio you think i'm lying to you when i say its a lab?

[dondude69]

I never knew there was a temperature component involved.

[kulhamex69]

What's up with the rapist voice.

[2009landscape]

wow very cool!!

[bstang93]

Love your face science!! :D lol

[GupperNZ]

Daaaamn you deserve a medal or something, for your smartness. "it's kind of hard to explain BECAUSE YOUR MERE MORTAL MIND CANNOT COMPREHEND IT!!!" is what he really wanted to say

[NurdRage]

@GupperNZ LOL

[piersremus]

I start to regret being a ass in class! "damn!"

[DMon593]

Miisssstterrr Scientiisst

[FaiLxTRaiN]

Yay, vids are back!

[annonxzSWE]

What does this help me for?

[whowasthat]

Your voice sounds like the guy from CoD Black Ops

[toocoolforu]

Can you eat it safely ? It looks delicious.

[drnjr31]

Frosty Beer Mugs

[tarnationsauce2]

Kipkay's balls drop or what?

[lunaticial]

it could be applied to a cpu to tell the system when it need to apply coolant

[inverseactuality]

I don't understand chemistry (10th grade, can't take classes on it yet unfortunately) and do not have the money to purchase chemicals and try it, yet I watch all of your videos whenever they come up in the subscription box for some reason.

[kiwiterran1]

i only got 20% out of 100 on my science test =(

[SIC66SIC66]

@kiwiterran1 Maybe because you spend too much time doing nothing, and not enough time learning? ;)

[kiwiterran1]

@SIC66SIC66 theres no holp for me..i was born dumb =(

[SIC66SIC66]

@kiwiterran1 Nah, everyone has got his skill, you maybe just didn't find it yet.

Btw, playing Starcraft is a skill if you ask me ;)

Do you watch/play SC1 or 2?
