NightHawkInLight's super CaCO₃ micro-sphere pigment recipe:
Sodium Carbonate (washing soda) ......... 20g dissolved in 200 mL water
Calcium Chloride (painter's desiccant) ... 10g dissolved in 100 mL water
Citric Acid (used for canning) .................. 3g dissolved in 30 mL water
1. Combine Calcium Chloride and Citric Acid solutions into one container.
2. Adjust the temperature of the liquids to be between 10-20°C (50-70°F).
3. Pour Calcium Chloride/Citric Acid solution into mixer and begin stirring.
4. Pour the Sodium Carbonate solution into the mixer and begin a timer.
5. Allow solution to mix for 1 minute.
6. Turn off mixer and pour the liquid into a separate container.
7. Wash the mixer with vinegar and water to prepare for the next batch.
***Make 3 total batches following steps 1-7, each time allowing the solution to mix for 1
minute. To save time you can make large quantities of the starting solutions all at once,
chill all of it to 10-20°C, and then measure out enough for individual batches by volume
just prior to mixing.
8. Make a fourth batch, mixing for an increased time of 5 minutes.
***Optional: Make a fifth batch at 1/3 scale, mixing for an increased time of 8-10 minutes.
9. Allow 20-60 minutes for the pigment to settle out of all batches.
10. Pour the water off the top of the settled pigment and refill containers with water.
11. Repeat settling and pouring off water 1-2 more times.
12. Cut a rectangular opening in the bottom of a disposable bread tin.
13. Line the tin with paper towel and a sheet of white printer paper.
14. Pour the pigment solutions into the tin, using the paper as a filter.
15. Pour extra distilled water over the pigment to wash it.
16. Once filtered, place the whole tin into an oven to dry at 100°C (212°F).
17. Collect pigment, breaking up clumps in a blender if needed.

This was a huge project and my longest video to date! A long overdue update to my IR cooling paint project, this time using common and very affordable materials. Besides the paint itself I was happy to discover some new methods for making size controlled calcium carbonate microspheres. That may prove useful for all sorts of things. www.patreon.com/NightHawkProjects
wonder if an airless sprayer might work, these can spray thick paint.
Could these pigment be mixed with car spray lacquer and sprayed on. Some of the colour shifting paints don't dissolve and have to well mixed into lacquer (ref: dip your car channel)
By far this video is the most informative and well designed video I've seen in some time. Concise, with references and intuitive explanations! The tech is superior in so many ways due to ease of use, price point and availability. The tech is also cutting edge with novel viewpoints. Most importantly, you have shared this for free, speaking volumes of your character and thought process. Bravo and thank you.
I wonder what carbonated water would do?
How about automatic Ikea shutters one with the cooling paint and one black. Depending on the temperature they one drives up an the other down. With that temperature control in a room would be pretty easy.
This is just brilliant...cutting edge science, in your kitchen! I tip my hat to you sir.
This is actually incredible! Seriously, he just took something that was previously very impractical and created a recipe that can not only be mass produced, it's also easy, safe, and inexpensive enough to do at home. And he posted it all on the internet. For free.

I'm a chemistry professor and I run a research lab. I spend an embarrassing amount of time consuming science content on RUclips. I can confidently say that this is the best research process I have ever seen demonstrated on RUclips. Presuming you have robust and reproducible data of all the observations you present in this video, this is easily a publishable project and I think it would benefit A LOT of people if you were to pursue publishing this work. There are a lot of people in my profession who wouldn't be inclined to follow the science presented in a RUclips video, but would confidently follow the exact same science if it appeared in peer-reviewed publication. I don't think they're correct in that perspective, but I know that bias exists. Anyway, please consider publishing this work, and if you wanted or needed any input to help pursue that I would be more than happy to offer any assistance I can. ABSOLUTELY EXCELLENT WORK!
Thank you very much!
Have you considered (or tried) using a clear acrylic paint as your binder/resin? You may lose the scattering effect of the water inclusions, but you may end up with a coating that has some environmental durability.
To test, just put some of your powder into some polyacrylic paint (Minwax makes one) and test rest them side by side in your box.
The other advantage is that a paint based solution would be applied using a roller.
@@jmacd8817 I'd like to see it tested with clear hobby acrylic paint as base and if some thinner is used, it should prob be sprayable with an airbrush or equivalent

"There are a lot of people in my profession who wouldn't be inclined to follow the science presented in a RUclips video, but would confidently follow the exact same science if it appeared in peer-reviewed publication."
Interesting since a large number of research papers and even peer-reviewed publications have been shown to be garbage. I guess you can chalk that up to the hubris of the expert class.
My company is in R&D for sky cooling liquid applied acrylic roof coating. We are using a crosslinking acrylic that "mends" together between coats to create a solid, durable membrane. Given that this recipe is out now..I guess it doesn't matter to keep it a secret anymore lol. I will make a new video with results of small scale tests. We currently have capacity to produce 30000 square feet of 60mil thickness of liquid applied membrane. It can be sprayed with a standard paint pump, or rolled on with 1-1/2" nap. @Nighthawkinlight thanks for this amazing contribution. This will not only reduce heat waste, but also reduce consumption of electricity for air conditioning. My hat is off to you!
Very much looking forward to seeing your results!
Wtf more info? What a gold mine for potential roofing applications.
I would seriously like to buy paint for about 100m2. I live in the Netherlands. If possible, let me know please
UPDATE:
Our test results were better than other coatings in the market, but only by a fraction of a percent! As we added more powder to the ratio, the resulting membrane developed microfractures, some of which went all the way through. So it was a no-go. We are now developing a prefinished roof panel system instead. This takes out all the guesswork and human error that occurs while spraying or rolling it out as well. It will take some time to recover from the losses incurred from the coating system tests. In short, we are giving a customer another new roof..
We will be putting together a panel coater conveyor system complete with heated curing. There are many hoops to jump through for metal paneling to be approved by the various testing organizations, but I am going to be optimistic. We have learned that using very thin coats and a more rigid acrylic base gives the sky cooling results, but it is not as durable. (pressure washer with brine added to the soap dispenser to simulate the expensive salt water test) We will likely provide a variety of sky cooling panels that range in warranty length and, inversely, sky cooling effectiveness. All this to say results will be coming in a few months more.
Thanks for the update, keep them coming!
I didn't scroll through all the comments, but in case no one else mentioned this about research article fees: when you hit a paywall (i.e., a journal wants to charge you for an article) you can often email the authors (especially the marked "corresponding author") and ask for a copy of the article and they will usually send you a copy for free if it's for educational purposes.
Those article fees are ridiculous and anyone doing educational stuff like this should not have to pay them out of pocket!
Also, like a lot of others said, this is really impressive work. Thank you for sharing!
absolutely love how this dude vanishes for months and comes back like "sorry for the absence guys my NASA grade research and development that I conducted in a barn took longer than expected" love the work and how well put together your videos are dude. I eagerly and patiently await future breakthroughs!
I would much rather watch a 40 minute well researched and well produced video once in a while than a blink-and-you-miss-it short every day.
Knowing how much NASA likes to "crank the silly thing"(actual comment in AGC source code as annotation for astronauts), I wouldn't be surprised if NASA already hired him.
Better have patience to wait, bc this is bs. He should stick to programming. No one coming up in science ever took soil chemistry. And people think they can just take a crack at it and independently arrive at stuff they could have looked up in school. This is worse than selling solar anywhere east of the salt divide in north America or bogus windmills with wispy blades. Hey everyone let’s whitewash everything like Tom Sawyer. Hey paint my fence for me, it’s fun! That’s all that’s happening here, fancy whitewash. It’s diminishing returns making the spherules. Just paint things white smh 🤦
Honest quality content takes time to produce and get results.

I am now 21 and you have consistently amazed me and thought me more than school ever did and I want to express my gratitude and love for what you do and who you are. Thank you.
Thank you very much!

I have considered putting this as a top coat on my Swamp Cooler. I also live in New Mexico.

Pouring spheres into the container was a great way to explain the why and how you went about the solution..... I look forward to seeing how well it cools the shed.
No joke, as a PhD candidate, I feel like you’re genuinely putting a lot of scientists to shame with such an excellent presentation. This is what good science is, not this ivory tower crap we’ve got so much of now. My PI acts like we’re real hot shit just because we have some reasonably fancy and nice equipment, but the way we do science is just not the way it should be, and you’re demonstrating how great science is when you do it right
Thanks, that's a high compliment
@@GeorgeWashingtonLaserMusket It's a bit of an oversimplification. It's easier to get published if you already have a good reputation, but it's entirely possible to publish without a reputation as well. The real problem are the large journals/publishers like Springer et al.
As a non-established scientist you're probably better off publishing to SciHub than through a traditional publisher...
Maybe we shoud ignore the fact that the "ivory tower crap" he points out around 18:07 had conclusions which "were super helpful".
The thing is, What you can start exploring depends on what you Know.
All learning is Good.
Having fancy machines can make some things so much easier to explore, which is Hot Shit !
I’m an undergrad involved in research and it pisses me off. We spend as much as the government will give us and get equipment that’s like $50 for a nut and our experiments don’t go anywhere because the shit breaks and there’s no one to fix it. I could do so much more with $2000 than my PI. He’s great, but science, like government, is too big and wasteful to do anything good nowadays. We should be exploding with knowledge because of the exponential growth of knowledge, but we aren’t because it’s being bogged down with white collar bullshit and they spend all their time in worthless fucking meetings while my own interests and ideas aren’t shit to them. I’m gonna save the world without them and do it on my own or with people who are actually bent on making progress.
As a chemist, I love how you make things my colleagues and I would spend thousands of dollars on to research, just with household objects. You are an inspiration.
Seriously, this dude is a legend. Been following his channel for years and he's like a blue collar Einstein. Probably a better comparison out there, I just can't think atm. His channel has gotten me through so many at home projects.
Er, about those thousands of dollars - where do i send my bank details ?
I always like when it's chemistry one can do at home too since I no longer have access to all the fancy stuff in the lab.
Dude, there are some damn smart people on RUclips and you are on the short list at the top. Your videos have always been impressive, but this one is out of the park.
As a side note, this is what the internet was designed for. What the academics, engineers, programmers, etc. were all working for. A place to share great ideas with the world. And for those ideas to get improved by others, which then leads to more improvement. Which is friggin awesome!
Like literally though, it was made to share scientific discoveries, papers, data. That was it's original purpose, back when that one guy connected all the computers around CERN to do just that. And then someone went: "Wait, what if this, but worldwide though?"
Your multiple rinse steps may actually shrink the size of your microspheres a bit. Nanoparticles have a very large surface area so, even though CaCO3 is pretty insoluble some it will dissolve in the rinse water. I discovered this was true when I tried making magnesium fluoride nanoparticles (as a polishing agent). Multiple wash cycles eventually caused the MgF2 to totally disappear! Using LeChatelier's Principle, I found that adding a very small amount of a water-soluble magnesium salt prevented this.
You also might be able to use this "problem" to your advantage if your smallest particles aren't quite small enough.
This is a wonderful tip which invites an experiment!
Holy crap, this is genius.
Just off the top of my head I feel like the most important parameters to test are to find a way to determine how much (if any) the Water temperature, Duration of each wash cycle and the nanoparticles size will contribute to how much degradation (shrinking) of the spheres occurs.
Once a consistent method of testing these parameters is developed and employed, this can be applied with a large array of applications where density, temperature and likewise even pressure (such as hydrostatic pressure in any type of stratified fluid) are key principles to how efficient said application can be.
Like using Aqua Regia for dissolving Gold.
This dude really just out here making lost recipes and coming up with new ones out of the blue every 3-6 months. Never disappoints

I had a dream about making this last night, and painting it on the roofs of houses, after falling asleep while listing to NOVA's "Climate Change Crisis." Hopefully, if I don't get to do that, someone reading this will and we won't fight others doing the same.
I'm passionately inspired and deeply moved by your determination to make this. Thank you for reminding me what it means to be a scientist. I hope you can get nominated a Nobel prize for this contribution to humanity's future.
Thank you very much!
Volcanoes and solar flares have more effect to "climate change" than humans ever will. I have no problem with the paint itself, but don't fall for this media-hype of the world falling apart because too many cows and cars belched out gas that natural processes such as photosynthesis can solve on their own.
any progress on making it a roof coating?
@@darwinjina I work on Buildings as an HVACR dude. Roofs have been increasingly turning from Black to white over the last 20-30 years. (I don't understand why they were black to begin with? Other than glare? But obviously heat efficiency should have always been priority over glare. The problem is keeping them clean, It is literally impossible. Roofing materials are some of the most durable/flex products on the market nowadays and they still stain and get dirty over time. Obviously we walk all over the roof to fix and install things. He brings this up in the video. Still, a white dirty roof is going to be far cooler than a black roof. But the real money in this project is finding a way to get it into PVC or similar roofing materials. Exciting! I love watching nerdy videos like this, and he explains everything in a way we can all understand. New subscriber here!

I concur with the pinned comment from the chem professor.
I normally don't comment on videos, but I just wanted to say that the content you are creating is singlehandedly pushing the boundaries of home science. In addition to how well the information was presented, this discovery could absolutely be a breakthrough in home cooling, and it is done using very simple materials and at a level that anybody could replicate. This is truly inspirational material for any future scientists; please keep up the great work.
Former STEM grad student here - I've seen the term "citizen science" thrown around in research papers! It's exciting to see breakthroughs like this happen in an accessible way!
I've said before that developing this into a quality coating material should be a government initiative and the product should be sold at scaled prices to an individuals income level with limits to allow enough paint per person to use for personal use. This technology clearly has the capability to effect our national electric consumption for cooling costs measurably across the sun belt for a large portion of the year and if leveraged into removable panels, could impact even more northern areas for the Summer months.
I think we are fast reaching the point that everyone should be contacting their government representatives to make this happen.
@@brianmi40 Will be doing that soon. Are you interested?
@@surajchougule4351 Thanks, I've picked up everything myself to make a batch, including 2 different mediums to apply it with (i.e. Spar Urethane). Am traveling now, but when home next I'll be making a small test batch and working on getting a good medium and proper mix to achieve the reflectivity.
In the meantime, more than a little shocked someone didn't immediately contact the Purdue guys and get this headed into the market.
SOMEONE is going to sell a LOT of this when that happens and the roofing manufacturer that gets it integrated into their product will do the same.

My folks live out in the sticks in Central Texas, no river and no wells. They have a rain catchment system but there’s been no rain so they’ve had to truck in water.
What they do have is humidity. They put a condensation recovery system on their AC and get a good 3-5 gallons a day off the AC for their 150 sq ft cabin.
My Dad and I are trying to figure out how to use these panels as condensate catchers to farm water from the air. Right outta Tattooine :D
We’re also going to cover their water tanks in this stuff and see how it holds up to the weather. The tanks aren’t shaped in a way that allows for the film shield, but right now the dark green tanks heat the water so hot we can’t bathe the baby in it. Just getting it down to ambient would be great.
BTW I knocked together a spreadsheet that gives you volume and price predictions based on how many square feet you want. It’s tuned to the local stores but should be easy to modify. Let me know and I’ll send you a Google doc link. (Edit: I mean, I'm sure you had to price out all that R&D you did, but this one could be published. I can polish it up to make it easier for people to customize)

Recommendation for paint/coating application: Attach two parallel guide rails to your canvas, place a dollop of your coating at one end, and use a squeegee perpendicular to the guide rails, wiping down to spread the coating evenly across the rest of the canvas. The height of the guide rails will determine the thickness of the coating.
Screenprinting.... without the screen. Clever :)
That's pretty much what I was thinking, at the right consistency this is less of a paint and more of a putty or paste. Would be pretty trivial to skim-coat large surfaces with a similar method to how you apply drywall mud or plaster on walls.
It might be possible to have a solder mask cut (probably in a diamond grid pattern) so you could apply it the same way as a pcb gets pasted. You'd probably need a more viscous coating for it to work though. Spread it on with a stainless scraper, and remove the mask. The fluid should spread out a bit after its removed, and gravity should flatten it out and fill in the missing spots. You could also play around with the thickness of the stainless mask too.
Nice to see that a few of us came to the same solution! However this would only allow for one size of panel, but especially for experimentation would make everything a lot more consistent
DUDE!! What you did on your “kitchen counter” for less than the cost of of an expensive meal for two was what colleges spend hundreds of thousands on to discover. Well, well done!!
85 % of college is a scam they wast your life indoctrinate you and then if you have a breakthrough Idea they will steal it and if your lucky maybe they will give you a small footnote in the patent that they file on your hard work and maybe and this is a big maybe you will get a $180,000 dollar a year job out of it your insight and hard work, good luck with college, more then likely you will end up working for Burger King or Amazon to pay off your scam debt.
He did a great job. But, it's important to recognize that these radiative cooling ideas are bouncing around everywhere these days. The research that is the foundation of it: chemical, coating, IR cam, atmospheric science is high-funded research. "Standing on the shoulders of giants."
If you take a killer photo with your iPhone does that invalidate, say, Ansel Adams?
Mind that he refers to several papers he read about it.
THAT is where that research money went to and exactly how it should be.

The way you are inventing truly innovative and socially productive things out of such accessible resources using principles of chemistry and the scientific method, is incredibly fascinating. I have never seen anything quite like it on RUclips.
We need more people like him who share valuable, important, helpful information (simplified) for a better world.
I worked in the coating industry as a formulator for about 10 years. For application you can potentially look into wire bar applicators to help apply an even surface. Application also depends on if the paint has a low enough viscosity and a low enough surface tension to be able to self level. You could also look into addition of a wetting agent which would likely be some sort of surfactant. Ideally this coating could be made much much thinner in which case you need to ensure an even dispersion of the particles without aglomeration. I loved this video and the level of instruction and detail!
If you had a thinner paint wouldn’t you need to apply more coats to achieve the same reflective efficiency?
Thanks for the advice!
@@jeremybyington I would think that getting it into a paintable formulation (brush or roller) would be a benefit outweighing the need for any large number of coats to achieve efficacy.
@@jeremybyington I guess it depends on how much of the effect is just a surface effect. Reflectance portion is surface effect. I'm not 100% about the emission part.
I was wondering if this could be screen printed. Perhaps on a shirt even....

here is a "pro tip": often you can just email one (or more) of the authors of those papers and just nicely ask them for a copy. Most often they will be happy to share it, since they are scientists and arent even getting paid anything from those absurd prices (they actually have to pay to publish their paper and get nothing in return from the publisher besides being published)

I think you should publish a paper on this. You've done the research, you have references to existing literature and you may well have furthered the field. Your brother is a physicist so you have an easy in if necessary. And by publishing a paper you may inspire some scientists ,like those who published the papers you cited, to further improve the method or even some of the things you talked about at the end.
Agreed. Making this a reference-able source could really make a difference.
So some paper mill journal can make 42 dollars per reader selling his work, as he mentions at 12:11? A number of people with experience in the field seem to have found their way to this RUclips video. What is the future, greedy science and tech journals or AI searches that can find all kinds of information? How many “peer-reviewed articles“ had to be retracted in the last couple of years? I’m certainly no expert, but when a major publisher like Wiley has to shut down 19 journals for low quality, anyone would be skeptical.
This is such an interesting video! I wish chemistry in school had been so inspiring!
My first job out of college was as a graphic designer For a 100-year old screen printing company. (I saw some other comments on that, and wanted to elaborate.) We used to print several different types of inks for decals. Some were water slide-off decals, heat transfer decals, ceramic decals for cookware, cigarette pack tax stamps, and temporary tattoos using makeup pigments.
All of these decals had some things in common. Each had an adhesive layer at the bottom. Above that was a base layer. Sometimes a white or silver layer to make the decal opaque. Above those were the colors, each one layered to create the design. Finally, a sealing clear layer. So the design was sandwiched between all of these layers. The layers need to be printed in reverse order on the appropriate paper.
You could make “tiles” of sandwiched layers with an adhesive at the bottom by screen printing them like giant decals. Then apply several of them to cover the products!
I was thinking along with the same lines. Take the human element out of it and use an extruder (3d picturesque) and get consistent layers over adhesive backing and cover it with a protective coating.
that is an amazing idea! I think they would need to be interlocking tiles though like some laminate fake wood flooring & like them be produced as rectangles or parallelograms for efficiency & effectiveness but this would truly be genius as one could create portable
pavilions,kiosks,car or RV shelters & so much more! I guess I'm thinking of modular set-ups but there's also the thought of finding a way to incorporate this tech into panels erected strictly to see if a large quantity of them in a zone of extreme radiated heat could reduce the rate of global warming without creating more waste materials that would be detrimental as so many other options do !

Didn't know. Thanks for the share!
I look for that Every time I'm at HD.
When NightHawkInLight drops a 40 minute video, you know he's about to drop some golden knowledge. (Lowkey wanna try this paint on my Sony cameras to see if they would actually work in the Texas sun)
Painting acetone on your cameras probably isn't a great idea
He is the son of Hawkeye from Mash so I would expect nothing less.
@@ChaosPootatojust gotta put non acrylic base coat on it.
@@ChaosPootato Haha Fair enough. Mostly just quipping on something relatable to fellow video/production enthusiasts.
Lol Nice name btw. Got some layers going on there.
Lol i didnt even realise it was 40 minutes lol.
I think this is a huge and enormous breakthrough. Maybe because other findings are hidden, but this knowledge given freely to the public is revolutionary
for spraying, there are special bigger spraying nozzles for different kinds of substances. The spraying gun used for Plastidip comes to mind. It's very viscous and yet sprays it in fine layers
I cannot put to words the amount of information and entertainment I get from this channel on every single video.
In my experience, if you reach out to the authors of a published paper, they are usually willing to give you the whole paper for free, or at a reduced price.
I tried with that particular paper but no reply.
@@Nighthawkinlight websites like scihub and libgen do help in that regard 😉
Reduced price? I've never seen that. Either they send you the PDF or they don't. Is it even legal to sell the PDF privately, bypassing the journal?
@@unvergebeneid The journal plain doesn't get a say in how you use your paper, because you haven't written it on their behalf. The academic institution though under employ of which you have written it, might have a word, but who knows what word that's gonna be.
I just use sci-hub, papers for free.
As a physicist, your application of research and scientific trial and error is incredible! The thought of microspheres has never crossed my mind before, but the presentation of your methods and all you’ve learned was VERY interesting. Awesome video!
Thank you!
Imagine that! Never crossed your mind, well then it surely must be good science! Lol you never once opened a soil science text book. If you had, you would realize this is based on a a rationale that neglects the biggest detail, which is it won’t work in the weather. All I can chalk that up to is y’all can’t conceive of earth systems. Your chemistry knowledge isn’t framed by how these reactions play out and interact in the environment. The only system that accounts for all of chemistry in a way that demonstrates how the periodic table works is in the soil. If you studied this, you’d realize silicon is best suited, not carbon. It’s like a very basic thing, you either see it or you don’t.
@@pbs41if3lo and behold, a lone youtube commenter who has all of the earth's wisdom.. ;-/
I don't think I have left a youtube comment in roughly ten years. This is some dope stuff dude, the opal video led me here and I'm seriously impressed by your process. Instant subscribe, please keep making incredible videos.
This was a super cool watch! I appreciate the work and thought you put into this, and it was interesting to learn about all the chemistry behind the project!
You should really write a scientific paper about this, to get this out to a wider audience. Your research deserves more recognition
I loved Mr Wizard when I was young. (I am 68). I have basic high school chemistry knowledge. Your presentation explained this process in a way that made complete sense. You are Mr Wizard Redux!
Wow wonderful job! This would be perfect for a small home, or tent! Maybe if the paint is combined with something that can flex, such as a fabric, or maybe vinyl it is possible to create a super cooling shirt! This could be the future of fabrics, especially in the hot sun! I could see plenty of uses for this for maybe even shade structures, to keep everyone underneath cool.
The idea of cooling fabrics immediately makes me think of nano-engineering. Maybe we can “tune” textiles with quantum dot technology to absorb heat when cold and radiate it away when hot. This breakthrough could be on par with semiconductors in terms of potential industries with applications including transportation, energy, housing, fashion, agriculture, and who knows what else?!?!
I'm so glad that you, tech ingredients, and Robert Murray Smith are aware of each other. Stuff is speeding up. 😊
You could keep this all to yourself until you achieve a patentable product and instead you’re doing the right thing and sharing your findings in detail with a global audience. That’s commendable as hell, dude.
technically if he filed a patent now after haven publicly sharing it, its my understanding he can reasonably contest any other patent claims posted after this release date. Hence patent pending; a period of time observed to find other patents or reduce the difficultly to extend or reject said patent based on supporting evidence and ability to file in a reasonable fashion. ~This is not legal advice.
No, he should file a patent. Why would him not doing that be "the right thing"? You don't believe that he should get credit or financial compensation for the work he's done? Is very kind and generous for him to share and the information is great. Doesn't mean he shouldn't get sa patent. I would. And so would you. It would be naive not to do so.
@@ChristaFree He should file a patent if only for the sole purpose of preventing someone else from doing so, and monopolizing it like medical companies did with insulin.
@@adondriel you do know a patent shares the information with the wprld right? You want insulin and dont wanna pay big pharma prices? Look up the patent amd do it yourself. Its only illigal if you get cuaght. And im fairly certain no jury will convict you for making your own insulin.
@@ChristaFree i dont think he created this
You are going to be our Summer Vacation weekly project fallow along. Mark Rober's channel has a "summer camp" but it's 300.00... and the flimsy little projects... my son is able to build them in about 15 minutes. And they're not really science. They're engineering, but they're not challenging enough, or practical. The stuff you do is amazing! We are here for it.
Not sure how or why your channel slid into my feed but it is one of the best things that has happened to me. I watched this video with the marvel and awe a child feels with their' first school science project. You explained everything I have ever wanted to know about cooling paint, why it works, and what my next steps are. I personally will not recreate your process but can move forward with my next paint projects enlightened with understanding and will choose my paint with the knowledge to make an informed decision.
As a chemist, I must admire your dedication. Some of what you have done here might be applicable to making artificial opal from sodium silicate solution , a project that I have been thinking about trying for a long time.
For your comments about using citric acid and it not being picky about water quality afterwards, I'll add that in soapmaking, citric acid gets used commonly and it performs "water softening" in the bar. When mixed with the NaOH used in soapmaking, sodium citrate is made in-situ, and keeps sodium soaps (i.e. sodium + fatty acid) in solution, vs them reacting with calcium and magnesium in the tap water, making calcium or magnesium soaps that are less soluble and leave soap scum, and the suds of the soap are less sensitive to water hardness (to a point, everything has its limits)
What is the usual lye/citric acid ratio?
Thank you as always for all that you do. By far my favorite RUclips channel and creator. Your videos and ideas are extremely inspiring.
The _Heisenberg_ of paint. Worthy of winning _The Best of RUclips Awards_ . Outstanding content.
I first discovered your channel years ago when you were building pvc air cannons. I was surprised by the innovative yet easily accessible designs for the homemade piston valve. Since then I have watched every new video you post. All of them are very engaging and informative. Your channel stands out as the gold standard for science channels on RUclips. Now that I'm older and have a job, I can finally repay the creators who have influenced me throughout the years. Keep up the great work!
Thank you very much!
You outdid yourself yet again.
What's more this time you even managed to outdo Tech Ingredients which is immensly impressive.
Compare them spraying 50 different coatings over the course of the whole day against your cake frosting application once AND your ingredients are even more accessible.
Bravo! You really could start a chemical company, you're definitely further ahead in this than any research lab out there. And then there's your non-flammable fireworks.
So I went looking for full spectrum camera conversions, then found your video on converting the cheap gopro! Now I just learned how to make infrared paint! Your channel is soo cool! Much of this stuff is over my head but I enjoyed learning this stuff exists! Subscribed! 🥳
What pleasant it was to watch this video.
I really learnt a lot. And I need to find some more about this topic.
Thank you and greetings from Portugal.
Probably going to get lost in the comments, but you should look into silica encapsulation of your particles to waterproof them. Tetraethyl/Tetramethyl Orthosilicate can be used in small quantities to create thin coats around particles of all kinds using many of the same methods you demonstrated, not the safest thing to work with indoors though.
Should be safe if you do it outside and very very carefully. Did a research project with TEOS recently, can confirm it does exactly as you said.
I've been looking into silane as a sealant and adhesion enhancer for hollow microspheres as syntactic foam components. Just my twopence worth... 😉
Do you think just mixing them together might work?
Yes, hydrophobic compound, the most important substance to prevent water absorb and mold growth
how do you make it? there's a simple to buy compound that I could use instead?
Actually reading the comments? Well I love your informative, cleanly cut, no nonsense videos. You really show off the magic that is chemistry!
You could be developing this shit for millions for companies but you just do it for our entertainment instead xD Love you!
Love your clever way of keeping people from skipping the sponsor section. I actually listened to what you were saying!! Good job.
You’re the first person on RUclips that I know of to say they actually read all the comments! And it only takes 10 minutes!
It's helpful when most of my comments are very kind. Thanks!
Ben, you can't imagine how precious your videos are to the community. Not only your stuff is really innovative, you also explain the science behind it, give information about your findings, and the best thing is, you make it open source. I'm not sure if you still working as a teacher, but if you do, I hope your students appreciate it.
Okay, this earned my Patreon support. I've been a fan for years and I think this video exemplifies why @NightHawkInLight is not only a RUclipsr's RUclipsr but a genuinely kind and caring human being trying to do his part to make the world a better place. This is such a beautiful application of Open Science and it is an honor to be able to support you in your work. My mind is always blown, I always learn a lot, and I'm always well entertained. Thank you!
Agreed but it also showed an example of a much too common instance of NOT Open Science with the research paper ($42) he purchased that like so many was behind a pay wall. I didn't catch the source of the paper but if it originated from a tax-payer funded institution and was available to the general public, if not freely so, it should not cost the tax-paying citizens to review.
Came for the airsoft machine gun, stayed for over a decade! It’s crazy to think about but I’ve been watching your content for more than half my life so far! Love your stuff, keep up the great work.
Thanks Ben for the video and the recipe. I hope to find the time to try it too! One useful side effect of the video is that the content reflects the integration of chemistry, math, research and a whole lot more, and I think it’s a perfect example of the application of those tools to real life. I’m sharing with my son in the hope he “gets” how math, science and other subjects are critical for his future. I got all enthusiastic, so thankyou!
you sly dog! using the bird to keep us watching during the sponsored segment is pretty clever.
all jokes aside, you are incredible, your content is incredible, and everything you do is cool, informative, and really feels like you, as a single person, are making real advancements in science for the layman.
The man knows his audience
Other commenters have said it better, but just, wow. These videos are an inspiration to future generations and show that science is approachable, testable, and practical. Amazing work!
For another applicator possibility, look up gold sniping. Gold prospectors use PVC to build a suction tube, like a reverse plunger, to suck fine, gold bearing material from cracks in river beds. It's like a big syringe. You could ad an end cap of PVC that's been heated and squished in a vice to give a flat applicator that you could also pull back on the handle to keep back pressure on the paint and prevent it from leaking out.
I have no words. You're just brilliant. Thank you for your incredible diligence and intellect.
That you very much!
you, applied science, braking taps, tech ingredients, thought emporium and others are doing a great job making highly specific and technical knowledge available to laypeople like me.
This channel is a scientific gem. The dedication and innovation is so admirable.
My grandparents used to paint their glass houses with quicklime and soda in the summer.
It does have to be renewed regularly when it rains, but the effect was clearly noticeable as the plants fared better in the heat and water consumption decreased.
So much better than all the teachers i have had in school! ❤ Long, but interesting till the end!
Unlike some other channels who either flat out lie or did minimal research and then stretch that out to an hour video. With deep sounding music to sound intriguing.
Meanwhile you: Disappears for months, drops a banger of a video full to the brim with interesting easy to digest information that you actually try. I love you man ❤.
Like you can tell that you actually took the time researching the topic and actually putting it to practice and then seeing about how you can put it in laymans terms for us
Two things: 1.) I love how proud he is of his work because 2.) he makes it very clear that this is genuinely novel research. I guess a third thing is that science is more accessible than we realize, but what's in short supply is a mindset, not equipment.
dude you explain like a quest giver NPC that every RPG gamer want to meet. ❤🎉
Thank you for your contribution to humanity, you have a greater impact than you can imagine.
Greetings from Greece!
Intentionally misusing kitchen equipment?!? I'm in!!!😂
I couldn't thank you enough for researching and sharing your findings. You're sharing gives the tools needed for creative minds to develop unique solutions to humanities everyday problems. This video is truly brilliant. Thank you!
Thank you very much!
I came up with the perfect original name for this coating you invented! It reflects light from the star in our solar system, and emits it’s own IR light into space! It should be called Starlight!
Its been a fun journey watching you go from making homemade foreworks when youtube was first created to making varying size nano particle sky cooling dust.
You inspire me to keeo developing my own personal projects. Making it clear that if you keep trying new things. You learn a lot of really cool stuff in the process.
Thank you
Just made it to the point you mentioned a white paper you ended up buying access to. Barring a few contracts, the researchers don't see any of that profit, so if you contact them directly they are usually more than happy to send you the whole paper themselves for free. Often, they end up interested enough to answer some questions too.
Couldn't get a reply this time unfortunately
@@Nighthawkinlight To add to this, there is an even easier solution: most universities have some public-access computers within the university domain, which generally has no-login access to any databases of papers (usually guest computers in the library). Or, just ask a friend who works for a university? It doesn't cost us anything to download individual papers the uni subscribes to, and everyone thinks the per-paper model is terrible.
You probably wouldn't believe me when i say that part of my choice to become an engeneer comes from this channel and your awesome ability to teach (i started watching this when i was 14 and now i am 18). Thanks for your dedication and keep up the good work, love from Italy
If you want to know and teach chemistry. Study agriculture. Everything you need to know about chemistry happens in the soil. It’s literally the interface between biology and geology. He’s taking a snapshot out of context that can be only appreciated after studying the whole picture. Draw your inspiration from how soils work. Want to learn about packing densities? Look at the molecular chemistry of clay aggregates. It’ll get heady very quickly and you’ll be sorry you underestimate the intricacies of soil.
Absolutely incredible. Not sure how I haven’t found your channel until now but you’re giving Nile Red a run for his money. Incredible content, down to earth explanations, and astonishing results. Keep up the great work sir!
Hi, for several years i decorated cakes but then became a housepainter.
Weirdly, they are more similar than they are different. You make a clean, smooth surface and decorate the edges. In my mind, the same thing. I admit that while caulking cabinets, i used a pastry bag full of caulk and a number 4 tube. Your video set my mind on fire. Thanks!!!!
You can easily get the exact end to use by getting a rose tip and using pliers to narrow the wide part. Cheers!👍❤️
I'm stunned by the amount of push you gave to this technology, and then I'm stunned you made it free, for everyone. Ben, if there's a time for you to feel accomplished, now's the time!
A coarse threaded rod should approximate a Mayer rod, for a quick trial. Also, this was a staggering amount of r&d and one of best chemistry videos on RUclips that I have ever viewed. Well done!
That’s a shame bc this is not chemistry. This growing a chemical garden. You can buy a kit if you want to hear words like nucleation and be impressed
@@pbs41if3Note they said best chemistry video, not best chemistry in a video. There is a difference, and the snobbery shown in your comment is ill-suited to the comment section of an *educational* video.
This video as well as the video you made before are both so awesome. Thank you for not rushing the videos and taking the time to explain things so that those of us that are not as well educated as yourself can understand the basics of what is happening and even understand why. I really enjoyed watching. ❤❤❤❤❤
You are such an inspiration man your videos have helped me find purpose in a dark place and are still helping keep me excited and inventing in a much brighter one. Thank you so much night hawk in light! I'll send you a video of my next prototype and I hope you know how much what you do helps people learn and feel alive and empowered with knowledge. Love and respect and gratitude to you brother. You've been inspiring and helping me for a long time and I'm glad to be able to thank you now.
Wow. He took something extremely technical, took it to the next level and then reduced it to a simple table top industrial process. Well done.
Packing multi-sized spheres has been around a long time, but making them small enough to have a paint which goes on fairly thin is tough. Making all that with ingredients which will reflect IR is pretty amazing.
Wow, you just made a video that shows in very easy to follow steps how (chemistry) research is being done and therefore bringing it out of the "elite ivory tower" area to the public eye. Teachers can use this in class on how to do research, the result can also be used for cheap cooling solutions (in poor areas), and you made an entertaining video just to watch for fun all in one! Well done!
Bro ,at least 60 percent of what you say goes right over my head........lol...... However, you do explain things in such a manner that I can at least get the general point.You make great videos and I greatly appreciate your own humility and readiness to admit mistakes. I ALWAYS learn several useful things when I watch your videos. Thankyou !
