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, personally, am thankful for your contributions to the field whatever structure you choose for their release. My input would be that you should feel free to do whatever maximizes your ad revenue per unit time invested. You deserve it.
NurdRage, I'm not a chemist, but your original videos on how to make real glowsticks by using TCPO, the dyes, etc, was actually what got me interested in chemistry at all! Since that time, many years ago, chemistry has become one of my favorite topics, and every time I see you post a video, it's a must watch. Thank you for all of the great science content over the years!
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.
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.
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"
I couldn't believe the idea would work until I saw the flash in the microwave 😲 Thanks for explaining that it doesn't 'just happen' and multiple timings need to be correct (evaporation, heating up, mixture). 🙏
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!
I'm 30 now and those moments of suddenly understanding something on an intuitive level that are so satisfying aren't happening as often as they did in my teens, but your explanation of thermoluminescence dating just hit the spot. Thanks man
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. 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.
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.
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).
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.
I do remember the original series. It took a while but I eventually realised that there was nothing stopping me and got a small home lab together. I'm a terrible chemist but I'm having fun and improving as I learn.
Green phosphorescence is so common I'd love to see a video delving into other colours of phosphorescence. Imagine glow-in-the-dark stars that are actually yellow
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.
@@RicoElectrico Nilered made clear in a video interview that he was not a chemist, but he was more interested in video and cinema. He makes videos because that looks cool on film, not for the sake of science. It's not a bad idea by itself, but it's disappointing if we're here for the science. Dont expect follow ups and improvements from Nilered, once an experiment is complete, he's over the topic and not interested by it anymore. It's not amateur chemistry. it's making a cool video. if he can get strontium nitrate from sigma he's not going to bother making it. what matters to him is the final glow. Nurdrage videos are science madness. make it work from the hardware store. hack it from raw dirt if you can hack it from raw dirt, just because you can. much more deep and interesting for me as a science interested person. Thats also why I love the aussie cubane guy. So much fun. understand how to do stuff in a garage that shouldnt work in a garage.
@@f4grx NileRed is an excellent "gateway drug" for people who didn't know they had a natural curiosity for science. "Making grapefruit flavor out of vinyl gloves" is a captivating title for people with only basic science knowledge. "Concentrating nitric acid with amateur means" is not... Until your knowledge grows and you realize how much of a pain the F-ing A it is that private people can't readily get their hands on WFNA. Then that title pretty much reads "I'll lead you to the holy grail" whereas the former reads "Another random excursion in organic chemistry that may or may not include tar".
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
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 🎄
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.
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
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.
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.)
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.
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 :)
Hello, Thank you so much for all your videos. Glow in the dark stuff in particular is very cool. I would be very interested by the purification methods to get the purest possible chemicals and the longest glow time. Also, what dopants and salts would give *red* colors? Thanks again
Would you be willing to cover the basic for the process of Phoshor coating a tube (IE passive night vision), and how it'd be gas-filled, etc? A bit beyond the basic DIY amateur chemistry 'purely lab process'...Just a thought, as I'd imagine it'd get good views. IF you consider a follow up, please cover your take on green phosphor vs white phosphor coating. Gen2-3 NVG tubes (IE green Phos) is less desirable than Gen3-4 tubes in White Phos. ...Naturally the immediate thoughts are how dangerous White Phosphorous is to work with, and if that's the same stuff that's powder-coated to those Gen4 tubes. Good content as always though.
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
Could a large permanent magnet pull the iron ions to the bottom of a container of the Al and Sr salts and concentrate away the iron? Dispose of the iron concentrate.
Love your video. You mentioned a mole. I've looked that up and still confused. You are great at explaining what you are doing. Could you explain what a mole is. Not the animal........How many moles are in a mole ? Sorry !
1:11 Quite the opposite, I remember it well. I was 18 and in my first year of college. "We'll need pure urea. Now, before you get any _stupid_ ideas and start pissing all over your lab..."
I had a hope that you would cool it down just like you heated it up to see if the glow lasts longer, Robert Murray did a video on luminescent panel it's interesting for solar windows. Could phosphorescent materials be used for energy storage?
Cooling 20 degrees to zero is imperceptible. You need 100 to notice, so it was easier to heat it. It would take me some time to get liquid nitrogen and I thought this video was delayed enough as is at 4 months. Phosphorescence is not good for storage due to the massive inefficiency and energy loss.
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)
i recently stumbled upon a easy way to make another phosphorescent material without any rare-earth, nitrates/nitric acid... i think it was with zinc chloride, Urea or thiourea, copper sulphate dissolved in water and i forget maybe some citric acid, maybe a splash of HCL (nothing was measured and just made some assumptions on amounts) and similar synthesis to the one pot microwave synthesis of N doped carbon quantum dots, its "low temp" never combusts, ends up clear-whiteish-yellow and turns to a hard resin/candy like material, phosphoresces once cooled, it is short lifetime and not very bright, also will redissolve in water and lose it properties, orange/yellow-green glowing color (probably copper doped zinc sulphide? QuantumDots?)... found this out as i was curious if i could make a phosphorescent material with things i had laying around, i ended up not messing with it much to see if i can get better performance, maybe boric acid would work better.
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...
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
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

I think it's really interesting how even small changes in dopants can have noticeable effects like that... cool video!

i recently stumbled upon a easy way to make another phosphorescent material without any rare-earth, nitrates/nitric acid... i think it was with zinc chloride, Urea or thiourea, copper sulphate dissolved in water and i forget maybe some citric acid, maybe a splash of HCL (nothing was measured and just made some assumptions on amounts) and similar synthesis to the one pot microwave synthesis of N doped carbon quantum dots, its "low temp" never combusts, ends up clear-whiteish-yellow and turns to a hard resin/candy like material, phosphoresces once cooled, it is short lifetime and not very bright, also will redissolve in water and lose it properties, orange/yellow-green glowing color (probably copper doped zinc sulphide? QuantumDots?)... found this out as i was curious if i could make a phosphorescent material with things i had laying around, i ended up not messing with it much to see if i can get better performance, maybe boric acid would work better.
I enjoy watching this stuff but for my and my neighbors sake I'm just going to go buy something pre-made. 😆
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...
i saw this on reddit
Part of club "I remember the original video from 2009" club here.
How about you make plaid? 😂 /teasing Great video!
I'd like to see how you would take this and make acrylic paint out of it.
If you then sent me the acrylic paint I would then send you back a painting.
1:12 I remember
That was 15 years a go at this point?!...
Uhg... I feel even older now...
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
