Honestly, your first glow in the dark videos are what I first started watching, allllll that time ago. I often showed your videos to my high school science teachers for project ideas and just some neat science. Thank you for being around for so long, and continuing what you do. I sit her now and watch your videos with my 5 year old. She has a love for science you are helping to grow into a passion!
I can't believe it's been15 years since that first glow in the dark video, that's some major nostalgia! Glad you're still here posting interesting, informative chemistry.
I do remember your first videos (not THE first video, but I started watching when you made the Nuka Cola glow stick, which was maybe your 10th). I subbed on an account that I lost access to and then resubbed on this one as my very first subscription maybe 10 years ago. You've consistently been my favorite chemistry youtuber for about 15 years now. I hope that you keep up the good work for as long as you continue to enjoy it! Thank you for the many hours of education and entertainment.
i'd definitely be interested in seeing how orange glow in the dark powder is made, as well as pink. as for related topics, i'd be really interested to see how the powders respond not only in different suspensions (like resin, paint, or nail polish), but also at what thickness does the powder no longer get brighter by being thicker. it's a bit outside your norm, but would be interesting to see none-the-less.
This is excellent and very careful, well documented work. Strangely, I have found the effect of cooling Sr aluminate to liquid nitrogen temperatures has relatively little effect on extending its phosphorescence decay half-life, whereas the effect is dramatic with ZnS based phosphors. I've never seen an explanation for this and wonder if the mechanism doesn't differ in some important way from the usual triplet state forbidden-transition system for many phosphors.
hmm... when doing research for this video i found a few other mechanisms for trap escape. Like quantum tunneling and quenching by other impurities. It might be that those effects are unaffected by temperature and become dominant at cold temperatures. So while the thermal escape might get switched off, the glow still decays at a similar rate from those other effects.
Wow, what an amazing video! If you're putting this much time into making a video you definitely should consider making it a video series where you show your progress along the way. Making the viewer feel they are exploring the science with you and is engaged along the way is better content imo but may have some other pros and cons. In the end the best videos are the ones you have the most fun making.
I am not sure how many years I have been subscribed but I know it's been more than a decade. I have seen most of your videos including the original of this great remake. Thanks for all of the great science and content NurdRage. Merry Christmas and happy New Year!
Fantastic job man! I actually like your method a lot more than mine, mostly due to how reliably replicable it is (the flash indicating the reaction is complete) Simply baking the reagents together like I did was much too "guess and check"
Homemade GITD (glow in the dark) compounds are always awesome and interesting because sometimes it means using novel chemical supplies that you can buy at hardware stores and gas stations like here. I also have tried GITD plastic against a powerful 365 nm blacklight (including Nichia NVSU233A) for sh*t and giggle, it can sure light up so ridiculously bright, covering the room in aqua light at night time, and I wouldn't recommend looking at it directly unless you like burning out your eyes (and even if you can't see the ultraviolet, don't look at the blacklight flashlight's business end when it's on either, it won't be pleasant).
hmm... not a bad idea.... but I don't have anything THAT radioactive... i'll have to look into it. (and i don't have the equipment to safely handle tritium specifically.)
37:18 is there a way to get just methanol from denatured alcohol. Not wanting to just get the ethanol as that's just easier to get at the liquor store.
@@jimurrata6785it may also be MEK (methyl ethyl ketone) as it has a very similar boiling point, but as you said, methanol is not used that commonly in denaturing anymore afaik
If you want to use the UV light for flourecent minerals as well, get one with a filter on the front. Since the filter blocks most visible light it should look like opaque/black glass.
Glow sticks work by a completely and totally different mechanism than glow-in-the-dark materials. But i do like your thinking. As for the actual mechanism, in glow sticks the light is generated by the reaction of peroxide with peroxylate chemicals. The cold temperature slows down this reaction. So they last longer.
I have some strontium nitrate road flares i have been meaning to extract, but just havent yet, mostly because i dont know what else is in there and dont know what that will do to the extraction. Shouldnt be anything other than some carbon based fuel and not be an issue, but im also lazy. (Edit) And yay! Someone finally used the cheap and readily available soirce of urea I've been suggesting for years.
Wow. Great chemistry. Well explained. Again pointing out how little i know. Smaller video's are just as much fun Nurdrage. Your work is top notch. Thanks.
I like the one long video, you did fine. I would like to see different mixes for the glow powder, see what other metals would do. I would like you to consider trying the pyrophoric method for some superconductors like YIBCO. I would like you to try some variants TiBa9Cu10O20, ZrBa9Cu10O20+, NbBa9Cu10O20+ Or try to make a magnet with Eu₁₆Sb₁₁ - supposedly 3.4-3.5 times stronger than a Neodymium magnet chemistry. Downside is Sb, I do not think that is a good material to work with.
it may be a good idea to filter the crude aluminum chloride solution before converting it to aluminum nitrate as the foil has traces of iron, which wont dissolve because the aluminum is more reactive but when you add nitric acid, will dissolve so it would necessitate greater purification later in the crystallization step also theres actually two types of C.A.N. fertilizer, theres the mix of calcium nitrate and ammonium nitrate like you have, but also what i like to call nitrochalk which is a simple blend of calcium carbonate dust and ammonium nitrate which has no calcium nitrate present at all, meaning some nitric acid would have to be added to dissolve it properly
Thanks for this video, I remember the original years ago. I would be interested to know if a good red is possible. All the commercial reds I've seen have been disappointing
Fantastic video!!! Thanks a lot! I really enjoy how much in detail you go, even on the more practical sides of things aswell as various alternatives and bugfinding. I don't mind the project compiled into a video like this instead of seperate videos, since here it's all fresh in the memory when you go into the itty bitty details of why and how. Also I would like to see other colors, such as red and orange, purple and teal. Is white possible? And seeing how to do ultra purification would also be really interresting! And Merry jollyholidays :)
I kind of lost interest in NileRed once he moved into his fancy studio/lab and became more interested in being a typical TH-cam personality. NurdRage in his basement lab remains way more relatable and more hardcore pure science, which I appreciate muchly.
This was extremely interesting! I'm not a chemist, but really enjoy learning about fields I have no involvement with; as such, I'd be more curious about other colours of glowing materials than ultra purified variants (blue glow was new to me, I've only ever seen green). The swordsman Musashi advised to know the ways of all arts & professions - which is much easier now with the internet than in his century, though also more difficult because the world is so much more complicated. Thank you for helping with continued education! Merry Christmas, NR 🎄
This is sweet. Just a hunch, but I guessed calcium was more blue based on complements... soooo... is copper going to be more reddish-orange somewhere? 🤔 Excellent video as always. Worth the wait.
Some amusing pareildolia: as he's saying the jars are disposable, I see the disappointed goomba dad face in the jar. (21:00, but the closeup at 21:38 makes it a lot easier to see)
Can we make a new glowstick video and also talk about the plastics used in glowsticks, I've found that the biggest brand worldwide now has problems with the plastic being very brittle and shattering instead of bending, rendering the lightsticks useless. The flexible plastic seems to be deteriorating and becoming like thin glass, it's actually dangerous as the liquid and internal glass tube fragments spray out all over the place...
This is unfortunate. What if someone has a lot of glow in the dark powder but what they really need is foil, pottery glaze, fertilizer and DEF? Can you show this process in the opposite direction? Playing the video is reverse doesn't work.🤣
I was there when the dark glowy magic was first written and I'll always be there for any new content like a mosquito that invades the bedroom it's slight hum always in the background waiting for NURDRAGE to post. Short form long form weeks or months between posts I'll be there
the modern glow-in-the-dark materials got just stupid. they can last for 24 hours. back than we were happy if the dino-stickers would barely glow for like 2-4 hours. XD
Yeh. Such materials in paint form can replace tritium glow cell strips in applications for signalization where them can still receive some light from external sources to recharge, and electronic signalization would be inaccessible or too expensive, like in signs for roads in secluded places and such.
Would you guys prefer my mega-projects to be compiled into one video like this? or with the individual steps made in separate videos?
Whatever makes you more money.
I am pretty sure that most of us will watch whatever you post however you post it! We are in for the long run!
In one video like this, it’s looks like a documentary
Whatever is the best compromise between enjoyment and profit for you
I prefer the longer videos
No strong preference. Whatever works best for you.

BTW did you get my message on the discord?
The lack of impurities @ 36:01 is unsurprising but still remarkable. Thanks for the videos.
Indeed that was a *striking* difference in performance.
It's those old glow videos that got me to subscribe. Has it really been 15 years already.
IKR... No shut up we're not getting old!! xD
I love these "make random things with random things" type videos.

Saw nurdrage + fertilizer +diesel and clicked the notification immediately.
I remember the ancient lessons, little did we know that was the golden age.
Thank you for all the great videos over the years!
thank you so much! merry christmas!
I love my glow disc golf discs! Night rounds with LED's on the baskets, glowsticks on the tee pads and UV paint on the obstacle trees!
Yes. My all time favourite Chemist TH-camr's back with awesome content!!! ❤❤❤
The long form video was a real treat!
Not that i ever expected it.
definitely do other colors! and if possible, can you make glow power in near ir that is only visible to regular and ir camera ?
Could you add any type of radioactive source like tritium and have a continuous glow?
hmm... not a bad idea.... but I don't have anything THAT radioactive... i'll have to look into it. (and i don't have the equipment to safely handle tritium specifically.)
Great video! So worth the wait. Always enjoy your work.
Me remembering that early video from back in the day, feeling my bones turn to dust.
37:18 is there a way to get just methanol from denatured alcohol. Not wanting to just get the ethanol as that's just easier to get at the liquor store.
Most 'denatured' alcohol is simply ethanol with Bitrex (denatonium benzoate) added. You'll throw it up but it won't poison you.
@@jimurrata6785it may also be MEK (methyl ethyl ketone) as it has a very similar boiling point, but as you said, methanol is not used that commonly in denaturing anymore afaik
If you want to use the UV light for flourecent minerals as well, get one with a filter on the front. Since the filter blocks most visible light it should look like opaque/black glass.
33:11 is this why glow sticks last so much longer if they are put in the freeze ?

YES, Ultra purification please. I'm such a nerd for those extra decimal places of purity.
Yes I'd love to see the ultra-purification, also we love anything glow in the dark
Happy Seasonal Thingy Mr. Rage! =3

I REMEMBER your original Strontium aluminate video!!! :)
Great video!
Thanks for the trip.
Good time to think about
Thenandnow thanks

I like the video before watching but one I know it derives a like and won’t let me down keep up the great work
They would be ideal for Christmas decorations maybe? Merry Christmas NURD.
BEST. CHRISTMAS PRESENT. EVER! WELCOME BACK!
More colours!

@@moogyboy6exactly, Nile seems to be careless for the views sake. It gets annoying at times.
Hmmm acid ? Fertiliser? Sounds like a good time🎉
Would this work as a luminescent radium paint? I know it used to be made with ZnS so if this is better then I imagine it works wells.
I am now wondering if one can do something similar to doping peanut butter.
Maybe try making red and if possible make a crude tricolour CRT with each of the powders
Would precipitating from sodium aluminate and calcining work?
I may have missed it, can you dope peanut butter?
Edibles 😂
Nurd rage can you make a video on caesium metal extraction from amature level obtainable stuff

Oh yeah what a great excuse.

'Making glow in the dark powder like nurdrage'
Thanks for obsessing over this project so we don't have to.
Thank you so much!
Isn’t it viable to just precipitate the Al3+ with alkali then re-dissolve? Oxidizing chloride seems outrageous 😂😂😂
who hasnt seen gold or silver........

You tricked me by omitting the rare earth salts from the description. That implies something simple. This is false 👎
Video description clearly says europium and dysprosium are used.
hang on babe, nurdrage just released a new video.
Very nice uwu
There was a glow in the dark alright. Whoop whoop here come da police...
Your silver inks don't work. And I think this shit will too.
