I remember watching your laser videos when you were under 100k subs and always thought this was the best tech/science channel on YT. I have less than 10 channels with full notifications on and you have always been one of them, can't wait to see what you come up with at 1mil subs and beyond!
Thank you!
@@TechIngredients I 100% agree. It takes a lot for me to subscribe to a channel and I almost never ring the bell. You rival This Old Tony and AvE, but have a much better mug.
@@jss331 For me, I'd say this channel is tied with Applied Science for most interesting and diverse content. TOT and AvE are great too
@@KingNast I just wish TH-cam would allow tags so I could bring them out of the woodworks. Imagine a joint project with these people. You just know someone would lose a finger!
Yeah, so hard to pick a favorite but you guys, AvE and Applied Science are the best. NileRed is a good one too.
I am a Chemical Engineer- this short vid is worth two semesters of Distillation classes. So you might pursue getting it to some colleges to try out. You would help a lot of students. You are 10times clearer on this topic than any Professor I had in college.
Then this is to prove that online teaching is more efficient than those often precinct junkie colleges filled with useless lecturers and students who never know/knew why they're there in the first place, eh? And good lecturers often get lost in the jungle so online teaching is pretty much a way to go nowadays.
@@sibalogh Or it proves that good teachers are better then shitty ones, no matter the medium.
@@sibalogh i have assumed he was a professor somewhere already...
@@warhag # That too, a few & far between good lecturers get lost in the jungle and hardly, if ever, get noticed.
ditto
The fact that you still read comments with this number of subs just proves you are a mad genius... Thanks for what you do!
A dephlagmator is like that agadmator chess channel wierdo foreign Guy.
Thus guy knows way to much he is more knowlegable than Thomas aquinus.
@@garrysekelli6776 is that the tatted camera dude?
You read every comment huh? Read this: Your channel is amazing!! The education industrial complex should be ashamed & embarrassed. If school would have been like this, I wouldn't have dropped out and started working fulltime at fourteen. My life would have been different. From the projects pick, to the work space you work in, to your clearly genius level IQ problem solving, and then, if that weren't enough, you have such a good communication style. Props to your camera/sound/lighting folks too. Thanks for sharing! One thing to please keep in mind, as you get more subs and can afford better equipment... not all of us are millionaires. Just to be clear, please continue to make your projects somewhat duplicatable for the average guy.
Thanks!
We will as that's the point of the tutorial. Why go into all the methodology and engineering if not to encourage others to use it?
Amazing job, sir! As a chemical engineer, I am speechless by the way of explanation of the material. Bravo!

It's not legal to distill fuel without permission from our masters either. Be careful.
@@kingearwig depends on the state and county laws. A lot of states let you produce up to 150 Liters or gallons of distillate product, I forget the fine details. But yeah, no matter what you aren't allowed to sell it for sure. I hope this information isn't outdated; it would be ludicrous to not be allowed to distill your own alcohol without a license.
@Robert Daggett We call it brain juice.
There is so much junk science out there it's refreshing to find great content delivered calmly and professionally. Thank you
This guy seems to know a lot about everything!
Very interesting.
I agree, while making great booze at the same time. ;)
"Today's '"junk science'" will be tomorrow's reality"---Paris Hilton, (2002). I often wonder why YT, in their conspiracy purge doesn't delete all the religion videos, as there is no actual proof of a god, specifically a god who believes spelling counts.
@@GetOuttaTheJohnBoy I'm with you on the religion think. Don't follow the spelling thing. WDYM?
It was a joke, because people don't spell very well anymore because it's all done for them. Just a joke commentary.
I was searching for hours for a video to clearly explain how column stills work and was getting half baked junk. You guys rock! Watching the video is pure pleasure, thank you so much for taking the time!

My favorite thing about this channel is that he constantly reminds me why I love engineering. It's a skill that gives you enormous insight into the basic principles behind most everything humans use or make. You might not be an expert at everything, but you can approach nearly anything and get a reasonable understanding of the process pretty quickly. Once you understand the process, you can adapt almost anything you find to do almost anything you want.
Agreed!
This is how people learn. I wish I could afford to pay this man or some one similar to personally teach / tutor my children five days a week. What a wonderful education experience that would be.
There are privately owned trade schools. I actually work at one. It's only for a specific trade, but the method of teaching and transferring knowledge has allowed us to focus what would typically be a 6 month college course into a 4 day seminar environment and test for competency on the last day.
I explained that not as a shameless plug, but because with some slight modification to dynamics and planning, we really could develop a much more feasible education system that starts at the base and builds a foundation, and then stacks upon that foundation with subsequent courses.
The real trick is to determine what relegates the specific path a student should take after the basic general education topics. That should also be modified to incorporate the important stuff and omit the stuff that is literally useless and wastes time.

I am currently studying chemical engineering and because of this video, I have more appreciation on distillation. Thanks a lot!❤
This is the most comprehensive video that I ever watched and performed very very well.
Thanks!
Stay tuned, and please subscribe.

Commies arent human.
I didn't know that's why they used copper. Thanks.
Also transfers heat really well. Lots of reason copper is used in distillation.
@SKIP AD not cheap any more lol
I love how thorough and professional your channel is. I also love the content. Thank you!
Love all of the topics you cover and the detail given to each subject. A true renaissance man! Found you a few years ago, if I recall correctly, from an audio actuator video showing up in my feed. No idea why it showed up but glad it did as I have a range of interests and you touch on so many of them!
I have a BS in Chem Eng (1981) and you did a better job of explaining distillation than did my ChE and Chemistry profs.
Great job!
you have BullShit in chemical engineering?!
@@lordjaashin bruh
well, sad for you, as a chemical engineering student, about to graduate, i cringed a bit during the video. no explanation for azeotropy, no column distillation, using ipa vs water in the beginning...
@@AltarParssoy He did not talk about azeotropy, but if you are making alcohol for drinking you probably will not reach the azeotrope anyway. What I found problematic is describing the force keeping the molucules together als van-der-waals. While the do make up some of the force they are easily outclassed by the hydrogen bonds, especially in water. Out of curiosity, how do come to the conclusion that he did not cover distillation columns?
@@julianw.9499 column design* that's what I wanted to mean and failed miserably. Because you can't just build a column without a proper design. It's the most important part of the design. He is doing a simple distillation with a column. That's all. No reason to introduce a distillation column if you don't explain it properly.
Good god his communication skills are fantastic.
I very much enjoyed this video. I intend to go back thru previous videos and will be looking forward to those to come. Thank you!
As a home distiller from South Africa I find your explanations so interesting and informative! The science behind it all lends such an appreciation of the art and hobby. I can hear my sugar wash bubbling away which I want to use as a firs run on my 2 inch reflux column. Thank you for the awesome channel!
1st view. You are an amazing teacher. You remind me of my fluids professor that was an amazing mentor. Thanks for everything you do. You provide REAL content!
I can safely give these videos a thumbs up before i even watch them. The information is always incredibly impressive and useful.
That freezer idea is brilliant. Thanks for the tip.
His approach to teaching is very inspiring. Love it. Keep up the great work!
someone else finds his voice relaxing and at the same time enjoys the flood of information?
Yes. I have only just got the time to give the attention that a @Tech Ingredients video deserves.
Yes, he kept my attention for the full video. Who his he, wish I had him when I studied chemistry.
The freckles make him so much less threatening. If he was my chem teacher I probably would’ve gotten an A instead of a C
yeah about 700k people
Why did i never have a teacher like you in school .. i cant even begin to describe who much i love this channel .. you are SO great at explaining and showing stuff.. and i find the videos to be way to short most of the times.. not because you lack describing something but because i could listen to you talking about all of what you do for AGES .. !!
thank you so much for all of what you share.. it is SO interesting and fascinating
Thanks!
@@TechIngredients i was typing to fast in my post.. who/how .. haha :) Greetings from Denmark .. keep up the good work
im watching and rembering 30years ago when i had to learn all this on my own in the back shed where i built reflux tower still... well done . all the little details you went over, so easy when you know whats going on.
Man I love this channel! I stumbled on the channel while learning about alcohol distillation. I've learnt more in these couple of videos than all others combine. Keep up the high quality work and beautiful demos and explanations. You have a viewer for life.
Thank you.
Seriously one of the most educational channels on youtube. You deserve more subs than you have, thanks for teaching us!
So True
I respect with infinite appreciation your indifference to having shaving problems. The transference of understanding is your passion I imagine. You're raising many young minds into something promising.
What an incredibly clear and in-depth description of the particulars of distillation. Really outstanding job.
That Still is a work of art. Absolutely gorgeous.
It definitely adds tension to have a beaker in the background slowly nearing the top with distillate...
There is a story about Tallulah Bankhead when she was older and was doing live theater. A younger actress sniped at Bankhead that she was too old for the part and that she could upstage her any time. Bankhead, in her signature husky voice said, "Daaahling, I can upstage you without even being on the stage." At the end of her next scene, Bankhead placed a Champaign glass that she was holding partly over the edge of a table and exited the scene. She ended up ruining the young actress' next scene as the audience was transfixed by the Champaign glass that sat precariously balanced on the edge of the table, waiting for it to fall. It was later discovered that Bankhead had placed a strip of clear tape on the base of the Champaign glass to keep it in place, barely balanced on the edge of the table.
@@DavidKutzler Thanks for taking time to put it here, great story.
Dude didnt even skip a beat to recognize it was about to overflow. A true multitasker
This was the best: "Look at my cool new thing" video I have seen. I learned a lot.
Great job. Very clear, lucid and expert commentary. Pleasure to watch, listen and learn.
I have always enjoyed our chats and in a weird way, this allows me to continue to enjoy your unique points of view and incredible knowledge base. I miss having you around, Eric.
i love the way your videos always start at the beginning. what i mean by that is you give context, which makes it very easy to follow and understand the significance of the subject. this makes even the topics i might not be particularly interested in feel relevant and it is impossible to click away, so i am almost tricked into learning something new and broadening my horizons while being entertained. great job! you well deserve the success you're having.
Thank you!
Indeed. I learnt a couple of things from this video alone that apply to other fields as well, like the T-clamp and copper HS sponge.
@@TechIngredients One thing that I would *LOVE* to see you revisit one day is your fluid-based air conditioner. Specifically, what can be added to it to have it output air that is not just a specific temperature and humidity, but purified and oxygen-enriched, as well. (The last two aren't as important in the countryside, but in cities where our homes actually contain air that is *more* polluted than outside air, being able to *FULLY* (re)condition our air without spending a small fortune would keep us a *lot* healthier.) Activated carbon on the final output seems to be how 'normies' do it, but what about bubbling the incoming air through oxygen-producing algae that would feed on any organic particles the air contained, both acting as a pre-filter *AND* adding precious oxygen?
(I'm not suggesting that this be presented as a cost-effective foundation for a biosphere, but...)
@@KeithOlson a very good growing medium for leagonair's disease you would have to add a starlisation stage.. UV light.. that would then create a lot of ozone out of the enriched air.. not good. But like your thinking.
@@williamarmstrong7199 Good thoughts!
I did a quick check and found this:
"UV light wavelengths shorter than 240 nm will create ozone via photolysis of the oxygen molecule.
UV light wavelengths between 240-280 nm will destroy ozone via photolysis of the ozone molecule."
Therefore, a standard 253.7nm source will both destroy micro-organisms by disrupting their DNA *AND* get rid of ozone. (It would probably be a good idea to sterilize both the input *AND* output air.)
Thank you. I don't speak English, but I understand all. And i teach language, watching your videos!
I have finally found a video where the still explained so thoroughly and comprehensibly. It always good when the whole process is demonstrated in real time action with corresponding notes. Thank you very much! Hope your channel will reach 1M subs soon!
Outstanding cameraman ... always. Thanks much ... again!
I'm so impressed with your power. If knowledge is power, you are one of the most powerful people I've encountered.

This was the first video I've seen on this channel , instant fan!!!
Started learning fermentation and distillation from my father and grandfather.
Love the science behind it all
Running a still and optimizing flavour and yield is really a wonderfull hobby (or business). Great content as always
New hair cut! Looks good!
Next, a professor’s mustache! 🤔
I really appreciate how multi-disciplined you guys are. Audio, jet engines, booze, etc, etc. Great stuff!
I disagree. This man has one one discipline. Science!
It's because he has a career of science behind him. Most people in academia come out this way, thus is why people used to respect professors and especially chemists (interface between physics and biology).
Same channel...???
What a great presentation. One of the best speakers I have ever watched.
Blown away. Best video I have seen. I feel I have a good understanding and ready to have my first go at this.
I remember tig welding a big stainless steel system for a moonshiner over 15 years ago having no idea what I was welding until I was almost done. It was really cool and a large automated system that had a 6 foot wide and 10 foot long foot print. He sells his for like $100 gallon for his apple pie, blue berry, so many... I don't drink but got a few gallons because he was so happy with all of it which I still think is funny as he knew that. My wife has had some and told me it was really good but 1.5 shots is her max. Today I like learning about them as we have a huge system at work for solvents.
You literally built a little oil refinery accurate all the way down to the bubble trays in the fractionating column. Mad respect.
I was going to say the same thing.
I worked on the primary crude tower at Husky-Lima Refinery back in 2014. It was incredible.The trays are made of perforated nickel alloy (think Inconel, Monel, etc). It's crazy expensive but impervious to nearly everything.
@@stevenbiars4817
Is hot hydrocarbon vapor that aggressive against alloy steel and even stainless steel that it requires inconel in the fractionating tower?!? I have seen USCSB accident analysis videos where oil refinery pipes are made from ordinary carbon steel (which was admittedly why it failed, lol).
@@gregorymalchuk272 Yes, the hydrocarbon fluids themselves are generally fairly benign, but some of the impurities in the feed-stock (sulphates/sulphides, chlorides, organic acids) can be quite aggressive. Because of the need to shut down the associated plant, repairing / replacing a tower's internals can be *very* expensive so every effort is made to minimise corrosion issues.
Cracking good
I love the math behind this!! Also, your communication of ideas is impeccable, as always 😊
George - "The Doctor of Distilling!" Yoy are a Blessing my friend, and greatly appreciated..
I ASKED AND I RECEIVED. thank you!
wow! I was thinking "geez, that's probably close to $10k..." *looks at wesbite* $1500???!??!?!! I'll take 8!!!!!
Make sure to get a permit. You can make fuel with a TSP but can't drink it. You need a DSP to be able to drink it. If you get neither you can pretty much just purify water.
Police: What’cha making there sonny?
Me: uhhh.. fuel?
Police: and what are you going to fuel with it?
Me: Uhh.... myself?
@ 74Vidrine, I presume that’s some US law in action ? Seems fucking stupid; In New Zealand I can brew, I can distill, I can grow tobacco, but god forbid I grow some weed =\
You can make and drink it all you want. It just can't sell it
@@robwilson2875 Unless you are John Lee Pettimore? ;0)
probably the best educational distilling video I've ever seen. Kudos.
Your videos should be around for a hundred years and more! Fantastic.
LOL.. perfect subject for all of us closed to our quarters these days! "na zdrowie!"
Presentation presentation presentation. I've been to 3 different colleges, and you put them all to shame, even combined.
That's RIGHT ! Oh How Many Way's MD's PhD's I've heard all... This Man Is Special EDUCATOR.... Beyond A Professor..... So Many Ways..... The Presentation Every Homeschooler Should Make This Part Of The Curriculum..... Motivational
Glad to hear you read all comments! Great video. I am learning a lot about alcohol distillation, also graphene and efficient air conditioning. Keep up the good work!
The description of all the little pieces of the system is excellent.
"Duh." 1:27
I love you, man. Your videos are pure gold. The amalgamation of quality, knowledge and passion.
And humor.
Also, water is capable of H bonding more times per molecule than ethanol, it's not just Vanderwhaals.
Water is a more polar molecule too, so stronger hydrogen bonding.
Hydrogen bonding is somewhat distinct from regular dipole-dipole interactions as well.
In fact, water, being a smaller molecule with no carbons and hydrogens, has a smaller Van der whaals force than ethanol. It actually works in the opposite direction of the hydrogen bonding trend.
Brilliant guy. Very good communicator. Easy to understand.
So beautifully articulated. Thank you!
Placing a refractometer on the condensate outlet stream will allow you to monitor in realtime exact component ratio more reliably and quickly :)
You will have to dilute the condensate with water to use the refractometer since you can't measure over ~80 %. In reality, you can't accurately measure over 60%, so dilute 50/50 with distilled water.
Yes, you could use a LED for this. The blue ones should refract more than red.
That thumbnail is absolute class. Having a cheeky sip.
I am a home distiller and as someone mentioned in a previous comment, your comments are informative and to the point. As home distillers, we are sometimes fed with untrue, unfounded and untested information, Thank you for not doing that.
This guy really knows his stuff I really enjoy watching his videos he has a way of explaining things that makes it very easy to understand keep up the good work and I’ll keep watching
I hope Brewhaus is sponsoring you, 'cause now I want one, and I don't even need it hahaha
Your videos are awesome!
i thought it was gonna be tens of thousands of dollars for a full set up but when i went to their website i found it was a lot cheaper than i thought haha
Roofing flashing stills are toys and dangerous
This guy is so much like me; He loves jet engines, loves home audio, loves physics and tech. You are awesome man, keep rocking on!
Very good video packed with information . Best video on TH-cam on this subject. Hands down . Thank you for all the knowledge !
What a wonderful explanation. Absolutely a person that knows what his doing. Thank you
I wish I found you sooner. It's amazing how you make these concepts so easy to understand. So yes please more distillery videos would be greatly appreciated! Thank you
I just love the way you explain everything in such an easy to absorb way. Long time subscriber. Thank you!
That was without a doubt the best video on distillation that I have watched and I have watched a lot of them.
Absolutely precision info to my questions! Best I have seen yet!
I always loved my classes in college that had labs, being able to see an idea transferred from text on a paper to physical application was always just amazing to me. The the part in this video when you pointed out the vapor traveling up the column and you could see when it hit the thermometer and the temperature started changing was just so neat to me.
The best science and tech channels hands down I have found. Thank you for all the time you put in and explanation each project.
TI - you are very clear in your explanation, making it clear as you go. Great video.
Bro, I love your videos. You come across as such a gentleman. I appreciate the effort!
I work in a refinery and H2S is a byproduct of our process. And somehow, I never knew that the copper had that effect on H2S, but it makes sense. You learn something new every day. Cool video!
I love this channel and the amount of different scientific things that are covered.
Its a masterpiece, a REAL masterpiece ! Every idea and thought i had is now totally connected. Congratulations !
Wonderful work! As always, in detail!
I learned something new about molecular attraction today.
Awesome video! When distilling in my moms basement many years ago, we used to draw a slow siphon from the frozen over swimming pool in the back yard to our homemade copper crossflow condenser. This let us have repeatable settings and results all winter. Then, in the warmer months, we would fill a large ice chest with water and several large bags of ice, with an aquarium pump very similarly to your setup.
Every video you make, I think of how you're exactly the kind of person I'd be, had I chose a bit more lucrative of a career. haha. Most of your videos are things I've done by making my own kit, or things I want to or plan to do, but currently don't have the resources to accomplish. But the innate plan every time, is to do it all myself from scratch. I can only imagine the excitement and knowledge your kids have gained from you and your endeavors. You make me want to be a more involved parent and have inspired me to involve my (step)kids in more of my hobbies and experimentation. As I've said before, you have a very enthusiastic fan in me for as long as you provide content. Thanks for the knowledge and inspiration!
Excellent description of a very clever system. Thanks.
Simply said excellent, very detail explanations.
One word. "Extremely tellented"
You're so good at explaining science. I learnt some things today with distillation, especially those plates in the column and why copper is important.
I really enjoy your videos and especially your way of explaining some of the process!
and as an undergraduate student with a project about ethanol distillation I had some insights for my own project, thanks for making this process understandable and even practical!!
I am so appreciative of your videos. Very informative and to the point. You're doing a good thing!
You are a gifted teacher.
I recently watched your channel for some of the sound videos and realized I had to watched this one as it aligned with the evolution of my 20+ year beer/wine hobby. Last year I thought I would try my hand at distillation. Living in a hot climate the tap wasn't an option for condensing. I didn't want to mess with bags of ice. One day while drawing a glass of beverage from a keg I saw the solution right in front of me! My solution was slightly different as I used a six gallon bucket of water in my chest freezer. it was nearly solid ice and held for a full run.
I'm working at a ethanol production plant, very interesting to see everything in glass and get a visual of the alcohol as its boils inside the reflux chamber, we're going to stop for maintenance next week and I'll be able to go inside a real one. Thank you for making me understand my work!
Can ethanol be purchased directly from production plants like yours? We purchased 4 ethanol burners as fireplace alternative and they are awesome. But we can't afford to use them. The fuel is $40 for a 4 liter jug which would last about 2 hours in a 36 inch burner. or $80 for a 4 hour fire. I've been searching videos like this one to see if there is a cheaper way of producing ethanol myself.
@@robertmorgan1550 The still is the heart of the process. When I was in college I built a still using a column filled with "chore girl" type metal scrubbing pads, and that worked OK. Cheaper than the special plates these people used. We distilled hard cider and got about 95% alcohol (I did not notice if he said anything about that, we can't get 100% alcohol by normal distillation, it has an azotrope); it even worked with beer, which starts at a very low % alcohol. The easiest way to start is with plain sugar dissolved in water, and add whatever yeast you can get; some yeast will stand higher % alcohol ( the limit in that step comes from the alcohol killing the yeast). Corn is cheaper than sugar but more work. But: in your situation, I would look into isopropanol, isopropyl alcohol, sold as rubbing alcohol, which is a next door neighbor of ethanol and almost as flammable; get an industrial grade, 99% pure, not the 70% that we see in the stores. You can find places online selling that; Amazon has it for $415 per drum, plus $202 delivery. If you live near a city you can probably find other distributors such as Ashland, might be cheaper or at least, lower delivery cost. Amazon also has 200 proof denatured ethanol (they have ways other than distillation to get away from the few % of water) but it is more expensive than the IPA, IsoPropyl Alcohol; they have various prices, and some may be 190 proof instead of 200, probably OK for your application.
I just discovered your channel...Just brilliant, extremely professional, competent, informative, with very detailed explanations....10/10...the topic choice as well is great...compliments, great job!
I enjoy your videos so much, you explain so beautifully and clearly.
