Top tip for storing liquids and minimising exposure to the air... Glass marbles. I used to do this with wet film developer chemicals. When you've used some of the liquid from a container, instead of trying to find and decant it into a slight smaller container, drop clean/dry marbles into the container until you get the liquid up to the top again. Then screw on the cap.
Another very absorbing video. Even though I may never reproduce one of your experiments, exactly, you present ideas and knowledge that is transferable to other areas of examination. Your demonstration of issues and the stimulating content are far more interesting than your contemporary UA-camrs. Thank you for your dedication to quality.
3:14 Is 95% alcohol that 190 proof alcohol mentioned here? What is the reason for different scales? So many questions. Please try help me/community to understand.
I second that motion. It's not often that I glean as much universally applicable useful concise information as i do from your lectures. Thank you for your tremendous contributions toward free public education. You bring the chemo to an epidemic of cancerous misinformation.
From one Alex to another, don't feel too bad about that cut on film for everyone to see. We appreciate all the blood sweat and tears that go into these videos, a little more blood this time but you know it happens... I hope you heal up quick! And I always appreciate your roving hand carrying shots keep up the good work.
Learned slowly how to cut things really effectively and fast. About 3x faster than the spouse and she isn't slow. Knives are nice to keep razor sharp and pro chefs tutorials about cutting things like the onions are way too complicated. Cuts make the master bro.
ohh I assumed the reason he did not want to show was due to monetization, since youtube is pretty strict with blood etc. I know a few science youtubers that have gotten into truple due to this. And its a sad reason to have your channel closed to (even if only for a week or 2)
I enjoyed this immensely, I worked for A. M. Todd Company 1984-1995, an Essential Oils Brokerage. I was in the Jefferson Oregon Field Office. My primary function was delivering 50 gallon drums preseason to the peppermint growers, picking them up when filled with 400 pounds of oil, off loading at warehouse, dewatering, weighing, and inventorying them. When shipped out each barrel was hand loaded onto a semi trailer with a drum truck. 100 per semi trailer, makes me sweat just remembering! 80% chance when you brushed your teeth I handled the oil that flavored your toothpaste 😁 Great Video, Thank You!
im not saying the oils are a cure all but something's it works and its cheaper, colds/shuffy noise's ect. works wonders or at least for me and it's somewhat good for asthma ect. or cleaning up the house/car ect.
We used to supply Bitter Lemon Essence to Schweppes Nigeria, an about this time of year in 1990 the packing staff reported someone had switched the lemon juice barrels from rectangular steel ones to more barrel-shaped plastic ones, nobody'd noticed. The consignment had to go (Christmas eve), so they used them anyway. What was designed to fit a standard 20' container did - with packing! During the journey, it evidently shifted. On arrival, we had a report back, that the doors had become self-opening, and the f##k-truck driver had been deluged in lemon juice! Well it was puetic...
@@JelMain I was fortunate that the shipper we contracted with understood the "Special Assignment," of moving our product. They would send the same man nearly every time. His name was Elliot, we would take lunch together after I loaded the trailer, we became friends and I stayed in contact with him over the years until he passed away. Our loading dock was like some kind of demented test for a driver to back into, over the years I actually had several drivers give up. 100-102 barrels per load averaged 500,000.00 USD in value, depending on market. Cheers Rahere! Merry Christmas!
You can definitely see the love. Very sweet. Felt bad for the pop because you could see him breathing a bit faster. Definitely seemed like he had that parental defense mode kicking in.
I just love how perfectly collected you both guys are. No screaming, no running around. "Hey, lemme see. Yeah, you might need stitches." "Yeah, just carry on" - grabs camera and starts taking close-ups ...
"Are you feeling dizzy" may sound like a funny question to ask, but some people really do pass out at by the sight of blood, and sitting down might help prevent a falling injury that could be very dangerous to someone's head. It is a good to be aware of this possibility.
This almost happened to me when I cut deep into my finger with an exacto knife. My vision greyed out and I got tunnel vision, luckily I didn't collapse as I was standing at that time.
@@Ergzay It can happen quickly but if you ever sense that again, sit down quickly to reduce risk of injury. I've felt faint a time or two after an intense work out, and experienced that grey and tunnel like vision for maybe 5 seconds or so. I cant tell really, because fractions of a second seemed like forever. I think I pushed myself into a hypo-glycemic state, and I remember passing out once as a young child, and now as an adult I sometimes feel really nauseous, dizzy, clammy cold skin and turn a little green. Symptoms not uncommon to very low blood sugar.
@@kreynolds1123 I have had many seizures, and I have learned to very quickly, find a stable place to anchor my hand, as I carefully, lower my body to my knees. If I am still conscious at that point, I find a safe place on the floor, to put my other hand, and get my head to a place away from anything that could cause damage. All this in about three seconds, but very careful and aware, as I am looking for a way to safely fall, as the seconds go by. I don't know why, but for some reason, once my legs are bent, and I am kneeling on the floor, my head gathers awareness faster than if I were to try to tough it out on my feet.
@@Inertia888 kneeling I belive raises the blood pressure in your head a bit. I have no clue if that's related your clearer thinking or not. Then maybe there's a connection between blood pressure and some kinds of seizures. As Your knees bend, it queezes some blood up. It limits some flow to your feet. And if your heart is maintaining the same pressure, some of that flow is redirected to your head.
Your teaching style is a stream of consciousness exercise. You simply explain what you are thinking as you go through an experiment. A great storyteller
I wish Alex a speedy recovery. I had a similar injury and can attest to the fact that it's not fun. While I swore like a sailor, Alex acted calm and professional, especially given the fact that he was cutting lemons.
This video is a good demonstration of the importance of proper knife handling techniques, which become more important when using sharp quality knives. I harp on my kids about keeping their fingers curled when cutting, and this is exactly why. A friend of mine cut the tip of her finger off doing this, went right through the nail and everything. I’d say he was rather fortunate he was not using more force while cutting.
Feel better Alex! Heal up quick! Also, thanks for showing us the the cut and the blood. It adds realism to the project and allows us to understand that we should always focus on safety an attention with what we're doing in the lab. Cutting gloves next time might be a good choice ♥
On bleeding: Hold your hand high. At least above your soldier. The blood flow to your hand will lower and the bleeding will stop. The pain will lessen a lot as well
You guys are the essence of what the internet should spread !! I wish many science teachers take exemple from your channel ! Thanks again for this awsome content!
You have to dig deep, but it's out there. I'm sure there are better platforms for a more curated experience, but I'm lazy and haven't gone looking. It really would be nice, tho. This also reminds me of why I stopped watching TV all those years ago: You used to find all kinds of interesting stuff to watch, but now it's all taken a BS reality TV spin. Well, that and there were less and less music videos to watch.

Of course that was before 80% of every one was "purged" with millions of dollars pocketed and never paid to the content-creators, who were essentially all ungraciously-used to generate revenue and build a substantial presence and wealth of ideas, all on what had became a huge "attraction"/"money-machine"...and then ...

Awesome video! Hope your assistant heals well! Also, on a note of the knife accident, small tips on proper knife usage for those watching: - Proper knife holding: hold a knife with the middle finger as close to the end of the handle as possible (middle finger can touch the bolster), and use both the thumb and index fingers to grip the spine (top part of the blade that doesn't have a cutting edge). Knives have their center of mass as close to the bolster (middle part between blade and handle) as possible, so this grip makes it so you hold the knife at its center of mass, which makes the grip more stable and firm. A quick image search on "proper knife grip" shows how to do this grip. - Cat paw/claw grip: retract tips of fingers to hold the stuff you need to cut as if you had a cat paw or a claw grip. It's hard to get used to, but it's safer. The point is that the cutting direction is never going towards something that is straight. The search for "proper knife grip" should also show these grips.
Interesting, as always. BTW: the chef's way to cut a lemon in half is to hold it between finger and thumb, creating an arch with your hand, with the axis of the lemon horizontal. Then you can safely introduce the blade of the knife, with no risk of cutting your fingers.
Way to hang on, Alex! "Yeah, I might need stitches, but let's finish filming. I'll just hold this blood-soaking rag to my thumb and keep filming while you keep on presenting!"
I gain so much from these videos. His ability to articulate in elegant and precisely direct terms the technical aspects of what are often quite complex processes shows his complete mastery. "Experts" of lesser intelligence often resort to 'high fallutin' terminology and more complex language to impress the listener with their supposed erudition. I am in awe of the scope and depth of his knowledge, of his communication skills and of his unfeigned humility. Thank you.
I hope Alex heals well and quickly! As always, excellent video where I learned some totally new things I can file away for use when a situation arises.
What a trooper. He's leaking fluid and has probably got a good inch and a half sized hole in him and he's got a camera getting close ups instead of going to get stitched up. About 8 years ago working at a hardware store I had someone bump into me while holding a hack saw at the work bench in the crowded receiving room. The blade gently tapped the back of my thumb along the knuckle along one of the creases and left most likely a single layer of cells intact because when I looked to check it I watched the skin peel itself apart and almost passed out where I was standing because I could see under the wrinkly semi loose skin. Tendons are effing gross. And I used to be a butcher, but it's different when your looking into your own body. It still makes me nauseous since there was very very little blood.
I'm reminded of a story from the classic book "Ignition!" by Dr John D. Clarke regarding d-Limonene. He worked at the Naval Air Rocket Test Station (which later became part of Picatinny Arsenal) and for a time in the mid 40's they shared test stands/facilities with Reaction Motors Inc. During this period the people at RMI were testing all sorts of unconventional concoctions for possible use as rocket fuels, and one of these was d-Limonene burned with WFNA (white fuming nitric acid). During this part of the program the area around the test cells was "blanketed with a pleasing odour of lemon oil", an occurrence so far removed from the kind of aromas usually generated by experimental rocket fuels that Clark felt it worthy of noting in his text. Thanks for another interesting video!
Off topic, but after seeing your series on epoxies I though to would be cool to see you tackle bioplastics. An hour or two of you guys talking about the core principals of bioplastics while running experiments on different formulas and how different amounts of this and that can affect the final product sounds like good entertainment to me.
From what I've seen on bioplastics is that they are made using non-petroleum sourced materials but end up still being plastics that have the same issue with biodegrading that traditional plastics have.
Yes please! One of my goals is to sustainably source all of my resources. Considering how much we use plastic this seems essential. (No essential oil polymer joke intended.)
I would really like to see this too. I've dabbled in trying out different approaches and recipes but I'm not as organized or methodotic as these fine gentlemen.
bioplastics are a plage for recicling ... try to mix Polyethylen and some Polyethylenlike biodegradebal plastisc and make some watertubes ....can u imagine what happens ? a company i know did go bankrup becouse they sold whitout knowing partial biodegradebals house water pipes .... and by the way nature alredy takes care of oure problem of plasic polution ... ther are more and more bacterias that can use everyday plastis and use encyms to breack them up ..... hmmm i see a real problem for my job future what if this bacterias did ther job to good ? we realy need stable plastic for our society :)
Man, I love how encouraging and positive you guys are. It's easy to be a bit cold or impatient when it comes to lab work but it's much better when everyone is happy. I know I find it easier to stay engaged when the environment is positive.
I am shocked that I just discovered you, but I am super happy that I did. Great instruction, even talking about the energy it takes to turn water to ice 144BTU pr lb, and the heat in the steam 970BTU pr lb. In the Refrigeration and HVAC course I took, that was somewhat mind blowing. It only take 180BTU 1 lb of water to go from 32F-212Fbut 32F 1 lb of ice takes 144BTU to become water and 1 lb of 212F water takes 970BTU to become steam.
I saw that cut coming the first time I saw him cut the lemon holding it incorrectly. BTW, superglue is a great instant stitch for minor cuts in a pinch. There is also liquid skin makes a nice addition to a first aid kit.
in his defence, he's a kid and most kids don't know how to cut vegetables and hold knife properly. But he handled himself excellently after injury though. didn't panicked, remained calm and kept chugging forward with recording without a single complaint
You can also use sugar to extract citrus oils from the zest to make what is known as Oleo-Saccharum. You could have then used that citrus oil infused sugar in your lemonade to give it a complex flavor profile.
Grandma used to grate the zest of lemon and orange, then muddle it with sugar and put it in a jar and store it in the fridge. Never thought it had a specific name like oleo-saccharum
Some days ago I harvested olives and I made fine extra virgin olive oil. All the suggestions you made for preserving the essential oil can be applied for the olive oil too. I found the perfect excuse to obtain a nitrogen cylinder 😂. Thank you 👍
Liquid Nitrogen can also be applied via Qtip to freeze warts, only reapply if after the scab sloughs any of the wart survived. Plantar warts however, should be excised from the side of the foot by a Podiatrist, because the roots are deep & scarring can hurt like having a rock in your shoe... forever (gasp).
It is usually a man that talks like this, and we always need to give so many reasons to get something to "play" with even if in the end we are doing something for the benefit of everyone else. Wives are so tough to convince. Good for you!
Professional chef of nearly 10 years here. Everytime I've cut myself you can tell how bad it is from the reaction. The not so bad just a little scratch cuts typically get some variation on every swear word and yelling possible. The truly bad stitches needed cuts typically get very calm, Gently place the knife down, and walk to the aid station. Hope he recovers quickly!
When trying to get those deep gashes to stop bleeding for either treatment at home, or to make a less messy trip to the ER. One or two wraps of electrical tape over the paper towel works fantastic at applying constant pressure. You can get about six to eight pounds of pressure per lair with electrical tape. Just keeps adding up. Be careful you don't cut off circulation.
A the advice of a sparky. Plumbers just wipe glue on the cut. The burning running up your arm is the clean / sanitization power! Don't worry it will peel off no problem.....
While working on cars, a mix of axle grease and dirt stops the bleeding as well. Generally I use electrical tape in a pinch. I find two stroke oil mixed with dirt works fastest on bleeders. I used to work on snowmobiles and always cut myself on something. Grease, oil and dirt stops bleeding fast.
Pressure dressings don't need to go all the way around, just fold up gauze (or the cleanest substitute) over the wound and then pull on the tape after sticking it to the skin on one side so that it pinches the sides of the wound together when you stick the other side down. If you ever do have to cut off the circulation on an extremity though, you must release the tourniquet no less than every 2 hrs to let blood circulate some before reapplying. Just fyi.
I found you through all your solar videos and love all your content. Your astute, no nonsense way of going about things is so refreshing! Thank you for being an absolute wonderful teacher!
This is one of those prime examples of why knife skills are important. When you handle a chef knife properly and use the proper technique the odds of this happening are severely reduced. Pinch the spine of the knife just after the handle so that the knife can't turn or spin in your hand, and rest your finger tips straight down onto the stuff you're cutting with the side of the knife against the flat of your knuckles. Almost impossible to cut yourself like that since your finger tips and thumb are never in position to be cut. Look up a picture or video of how the pros do it and never slice your digits again. It's worth it. Plus you can go faster and more accurately. Sucks that happened in the vid but hopefully others will take the two minutes to educate themselves. Excellent vid, fellas!
I've had several of those 'marginal' cuts heal perfectly by running the coldest water available over it until the bleeding stopped, a dash of alcohol and then more cold water, and as quickly as possible closing the wound under pressure and absolutely, positively not disturbing it for a day or two. Butterfly strips are good, even under a band-aid, and I've actually splinted a finger before just to avoid any movement. I remember one particularly clean cut managed to stitch itself back together in less than a week, though I still taped it to make sure it wasn't going to pull open at some inopportune time.
The pressure is the important part. Some plasma seeping is alright, since that is where the platelets are. Firmly pressing at the interface point, to stimulate the glue effect. And...if it hurts, well, don't do that...
It was hard for me to see the exact angle and depth of the cut, but superglue works great. It looked deep enough that there is not going to be a flap of skin that will eventually die and dry up (i hate those kind, usually due to a shallow slice, where the top surface doesn't have enough bloodflow to reattach, and it turns to leather and catches on everything). Usually just gotta wait for it to die, which protects the underside of the slice that is raw, by the time the lid dies and dries up, it's time to cut it off as the underside has a layer of new skin by then. Paper thin and pink, but then ya can chop it off. I hate those low shallow cuts on fingers, always catch on pant pockets.
Until a few years ago I never bothered with cleaning small cuts. I’ve worked in metal fab my whole life so I’ve had a few. A little electrical tape or duct tape and I would just keep it taped for a couple weeks until it grew back together. But a few years ago I had a sharp metal burr poke through my glove and into my left middle finger. It was literally the size of a pin prick, it didn’t bleed very much. I put a bandaid over it because we had them handy and went back to work. A few hours later my finger swelled to 4 times its normal size and turned red. It felt hot and I could feel my heartbeat in it. My boss sent me to the emergency room where I received antibiotics through iv. I still wasn’t taking it very seriously and felt like everyone was making a big deal out of it. Then the er doc told me that I had a good chance of losing the finger. That night I had a fever and I have never felt so awful. By the next day the fever broke and the swelling went down. I got to keep my finger. I take cuts more seriously now.
SUPERGLUE is the charm for clean sharp cuts! leaves a little scar, burns like hell but u stop bleeding instantly and are able 2 go on... that´s what it was invented 4!
I think that's why he said he was only filling it 2/3 full. He can thaw it, add water and sugar, and it's ready to drink. My guess is that he's done this before and knows the ratios that produce lemonade to his liking.
95 percent of the world use Metric/Celcius and being from Aus I really appreciate how you mostly use metric. Saves me from having to pause the video and google a conversion every minute or so 😋 Obviously the US are slowly transitioning to Metric, but I can see how this can take time..
Every dad knows that once you say “don’t cut your hand off”, that it is a moral imperative for the child to at least make an attempt. But what a recovery and right back to work. That’s work ethic’s. A trait so hard to find these days.
I know the itch I had to get closer and closer to the table saw blade after my dad told me that. Then he went and bought a saw-stop the next day and I had to install it, haha. Now I worry about the same things with my son. And see him get mad and become more reckless. Sigh.
As always, thank you for interesting and informative content. I rarely have time to watch longer videos, but I schedule time to watch yours. No one on UA-cam condenses as much quality information into a given time frame as you. Thanks again!
orange oil(cheaper to buy than lemon) is my 3rd most use solvent for cleaning, right after water(with soap if needed) and isopropyl alcohol. it will pull the glue from stickers and labels off of things fast and smells great. also perfect for removing pine pitch from your hands.
If you really want a really good degreaser and an excellent solvent for cleaning glue, then try Turpentine. It's the mother of all terpenes the same family of chemicals that include limonene and Tetrahydrocannabinol.
This is such a great channel, I have been watching since lasers was your main focus. I wish my dad was as interested in science/engineering as I am, I would have done anything to grow up with someone like you. I hope you keep growing and putting out such amazing content!
Yep, as someone with a lab of unbelievably sharp things, I concur! I had the unique situation of spending several years and countless $$ on microscopy equipment, And then another room/section of the lab a separate business… of woodworking, Specifically hand tools, and countless years chasing the perfect edge. It was only a matter of time until I was testing ways to get the sharpest edge possible no matter the cost. Damn curiosity! So I’ve had my fair share of bone deep blood gushing cuts. Where a simple slip can take off a portion of the finger Finally I just quit going to the emergency room and keep a “stitch up kit” in my lab. Also, medical grade super glue which is what they used on me most of the time. My cuts were always to the bone or close, and in areas that hardly could be stitched. So a little investment in the proper supplies and materials is a good idea 😂 and practice before hand so you know what to do when the shit hits the fan, and you don’t contaminate an open wound or a missing finger. They’re all in my lab has always been, Hospital only when body parts start hitting the floor. Unless I turn into a serial killer… Which is looking more likely by the year… That rule shouldn’t be hard to follow. Was letting a good friend borrow a piece of equipment for a big job, because his failed the day before. $18,000 worth of surgery and dental work later, Sometimes I wonder if I will continue to fine his teeth fragments on the floor when I do a big lab cleanup. Worst non-lethal accident I’ve ever seen. But it really wasn’t anyone’s fault because the building was being remodeled and the power cut in the middle of him using this machine. Even with the backup lights, the loss of RPM and such a sudden change in motor torque, he didn’t stand a chance. Be careful out there folks
There are different versions of medical glue out there. If you want the best option for your dollar, or just can't get a hold of the proper medical glue that would be used in a hospital, then try out vet bond. It is safe for human use and much safer than the little tubes of "medical" glue that are found on places like Amazon. Only downside is that since it is used with other closure methods it is a bit weaker. The little "one time use" tubes you can more easily find seem to work fine so there isn't anything wrong with them. Other than the fact that they're super wasteful since the packaging isn't designed for multiple uses and you don't need a full tube a lot of the time. I also question how sterile they actually are and the overall safety, but if I had no other glue around I would still use them.
@@Santa-614 Believe it or not it was a tablesaw. I’m a machinist and tool and die maker by trade so I’ve worked around a lot of lathes and Mills and you’re right. They can do some terrible things. I’ve always used the best I could afford and I had just purchased a “saw stop” brand table saw. They are claim to fame is that they can immediately lower the blade within a split second when it senses contact with skin. So they literally are 1000 times safer than normal table saws… Which are usually the most dangerous tools in a shop. I said it all several times and the wound on my finger was so minor that it didn’t even draw blood. It’s within one millionth of a second the blade disappears below the table, because usually if you touch the blade even just a little bit, it will pull your hand into it and you’ll lose at least two or three fingers. A good 10% of the woodworker so do it professionally and have for years are missing several fingers from tablesaw accidents But the building was being renovated, it was a huge industrial incubator for small businesses. I was in the middle of a large batch of guitar finger boards that I was cutting on the table saw. I always lock my shop doors when cutting….. so no one could sneak up on me when using equipment like that. But the maintenance man let in a good friend of mine without me knowing, which was no big deal and a normal thing because I always had people in clients visiting. And sometimes I would have the music cranked up pretty loud and it was a huge warehouse type shop. So you might not hear someone knocking. He snuck up behind me without me even realizing he was there, and he was standing directly behind me DIRECTLY IN LINE with the table saw blade. The maintenance crew doing the remodel accidentally cut the power for a few seconds, On the whole building. which reset the breaker in my shop and powered off the table saw. I was cutting extremely hard Ebony wood using a push stick, so not only did the few seconds of total darkness totally throw off my senses… But as the blade jerked and began to slow rapidly it quit cutting and it grabbed the fretboard blank… and push stick, throwing it right past my head … If you’re not used to big powerful tablesaws you’d be amazed how fast they can throw something across the room. They can throw a 60 pound billet of mahogany well over 100 miles an hour up against the block wall and break the brick That’s why you always use a push stick with the table saw, so that you’re never in line with the blade and path.. it all happened so fast, there was so much blood. Immediately got him down on the floor because he looked like he was going to pass out, call 911, and helped him keep pressure on it as best as we could but without knowing the extent of the damage you don’t want to be pushing on somebody’s head to hard. I grew up in a family of doctors, forensics investigators, and Taxidermist.. So I’ve seen some terrible shit, mangled bodies, and awful injuries. So I knew it was not life-threatening. But it was still pretty damn bad and gruesome We looked for his teeth over the next week or two, and even with insurance I paid about $15,000 for his subsequent surgery and dental implants. I felt so bad because he’s one of the nicest guys I’ve ever known. The craziest part… His girlfriend was with him, they had just met a few days prior and it was their first date. He was bringing her there to show her my Guitar business because she was a musician… So it was literally like the first hour he had been around this chick. Now 15 years later they’re married with several kids. At first I worried that maybe the trauma had caused them to bond and maybe they shouldn’t have gotten married so soon. But they proved me wrong 😂
I did this once, but I don't have knife skills, cut the tips of my knuckle skin off instead of my finger, on 2 knuckles. Was actually worse than just cutting my fingers as would keep splitting open all the time due to it bending all the time.
Sir, I’m really enjoying watching you go through your experimentation in real time. Your channel only came to my attention today, and this is the second one of your videos that I’ve seen. I’m only part of the way through it, but I’m afraid I’ll forget to tell you that the water that you’re draining off from the separator, it’s not just water. It’s hydrosol. It’s a valuable byproduct of your essential loyal production, and I think you’ll find you have a lot of uses for it if you want to look into it.
It is also helpful to flood the bottle with nitrogen just before decanting the essential oil. Nitrogen is only a tiny bit heavier than air, but it will remain in the bottle long enough to be displaced by the oil. It's a lot less complicated than the "nitrogen packing" demonstrated in the video.
@@TechIngredients i wish a speedy recovery. I have cut my self similar a few times, one with a band saw even, so I winced hard. Good luck and rest well
@@byrdhartley9014 Adding a saturated solution of sodium chloride will not base it, and help drive off water which in turn would require less anhydrous magnesium sulfate.
Thought I'd pass along an interesting phenomena I discovered by accident. Added a little bit of Eucalyptus oil to the water in a cool mist humidifier tank which was made of clear acrylic plastic and opaque base plastic. Didn't empty tank after use and a couple days later found that the acrylic and base had been "etched" and to some degree melted or starting to dissolve. Essential oils seem to be pretty powerful! Hope this info can be put to some use. Interesting and well done videos. Thanks.
Electrical tape is the best to keep you from leaking your electrons, just don't wrap it too tight, you would be surprised how much pressure a couple wraps puts on a cut.
Nop, I will not be suprised. :-) Have used it with good effect many times. Often on top of a band-aid just to have less clue from the electrical tape sticking to the skin.
Wonderful video! You are definitely a techie's techie. Although I've worked in multiple highly technical fields for more than 40 years, I am wow'ed by your expertise. I thank you dearly for your efforts and production of such high quality content. SUGGESTIONS: optical calumniators, ring laser gyros, rate integrating gyros, RF antennas (directional, omni, dipoles, long wire, horn, etc.), microwave systems.
Yet another exceptionally informative video , right down to the reason for using Cu in bubbler plates, and as always you don't hide the mishaps. Its not often I encounter people that I would want as a teacher, its even rarer that folks impress me to the point of wishing they were relatives. Your videos never disappoint in form or content. Thanks for your efforts to educate, enlighten and entertain - never enough 😀
You can also use the oils in a diffuser, to give a nice atmosphere to a room. Diffusers pump out a relaxing mist from the essential oils. They are very popular in the U.K.
I did a similar thing when I was chopping rhubarb at age 17 (almost 40 years ago now). Alex handled it even a bit better than I did. 7 stitches and still a curved scar on my left ring finger.

It's also worth noting that there's a few more interesting things that you can use lemon oil for, and it doesn't even need to be pure for some of them! Highlights include thinning finishes and paint[1], diluting into a great cleaning agent[2], and my personal favorite: melting styrofoam![3] 1: You can dilute Tung oil 50/50 by volume with technical grade d-limonene ( I'm not sure if food grade is fine for this ) to greatly reduce Tung's natural viscosity, making it easier to apply the thin coats you want to use. 2: You can mix a solution of food grade or technical grade d-limonene with water to create an impressively good cleaning agent, changing the ratio of Oil:Water for the desired strength ( I'd start with 1:1 and increase water if it's too strong ). Note, however, that the oil and water will separate over time, so you need to agitate the solution to keep the oil in suspension. You could probably add an emulsifier to the solution to help with this, but I haven't personally looked for what may be compatible in terms of shelf life and not leaving a residue. 3: Seriously, d-limonene and styrofoam are like a non-toxic version of acetone and styrofoam. You need a surprisingly small amount of it for the volume of styrofoam it can dissolve, too, so you can do fairly interesting recycling processes like filling a container with water, putting in enough d-limonene to cover the layer of water, and placing in styrofoam chunks - the styrofoam floats on the water, keeping it in the oil to break down, which then consolidates with itself, and once the new consolidation weighs just a little bit more it will sink into the water and allow new styrofoam to enter the oil layer for breakdown. The consolidated plastic is usually a bit gooey unless you evaporate off all of the remaining solvent ( the oil ). The final result are these weird little chunks of polystyrene, the plastic that styrofoam is made of, which you can use for shaping, or melting into a mold at a fairly low temperature ( like... 200f? )
When I was a line cook in High School, I cut the tip of my index finger off on the heel of a chef's knife when I was cutting lemon wedges. Lemon juice definitely feels fantastic on open wounds
I hope Alex recovers quickly! I saw that cut as his knife was dropping any my heart sank, best of wishes to you both! Side note. 212 f° is 100 c° Either our gracious and most honestly most awesome host was frustrated with doing conversations or distracted by concern for his son.
this is the second knife incident you guys have been involved in!!!.. i appreciate the lengths you and your family go to to bring excellent science to us. stay safe!!!!
I love your videos. I have a small 160 tree tangerine grove, just got and tried a still, and now have new things to try with next years harvest. Thank You
This is one of my more favorite recent videos from you! Simply because you arrived at a process the same what I did. I have all this waste material, what can I do with it?! This my own impetus into the journey of distillation techniques. As always, I've learned a lot from your methods and will incorporate them into my own. I could geek out on this process and discuss it for awhile but here are a couple quick tips of my own. 1) For Limoncello you want as much as the rind/yellow part and as little of the inner white part as possible. It makes it bitter. Zest it into cheese cloth and macerate from there. Trust me, you will notice the difference. 2) For oil extraction, try freezing the pulp first to help break down the cell walls. I don't run it through a food processor like you do so maybe this is redundant but I would be interested it makes a difference for you.
One minor thing: You mentioned low flash point oils for candles. I often use left over cooking grease but the low melting point (but perhaps high flash point?) tends to drown the wicks. I would love to see a video from you on this topic!
I worked as an engineer at a food packaging producer here in the UK and we used neat orange oil to clean the glue guns ,it's relatively food safe and dissolved the hot glue used to stick the induction welded membrane into the bottle/jar caps , that orange oil was nasty one drop on you're skin and if you didn't wash it off quick you'd end up with a sore patch for days that stank of orange till you'd had several showers... I got some in my eye once and Christ it felt like someone had driven a nail into my eyeball . Yes I was wearing safety glasses but a small drop still got in . I had a bright red blood shot eye for over a month. I got so sick of the super strong smell of orange I still can't eat them.
31:00 Not everyone has a tank of nitrogen: You can buy a product called "Bloxygen" which is argon in a small can with a straw. After opening a can of stain or whatever, you add a shot of that before closing the can. It makes a heavy layer so you don't have to fill it up the void in the can completely.
One of the few ocassions that i can remember that the unsolicited presentation of a commercial product results interesting ;) Only trying to be humorous, no bad blood at all, friend.
Gas mixtures do not form layers. Argon will not sit in its own layer, it will mix with the rest of the atmosphere in the vessel. If you want to flush out air, you have to add a minimum of that volume of argon.
I always feel as though I have gone to a college chemistry class with your videos. Your methods of teaching and explaining what's going on make these chemical processes understandable as well as entertaining . You almost had me reaching for my car keys to go get a tank of nitrogen. Don't know how else I would use it, but at least i would have it. Thank you..
I have been watching you for number of years now, and have always deeply enjoyed your content. The breadth of subjects covered is perfect for people who have boundless curiosity about everything and anything. There has always been something in my mind that found your content almost soothing... It was not until today that the calm, concise way you explain subjects triggered a sense memory; and reminded me of many childhood hours watching Don Herbert (Mr. Wizard). Thank you for reminding a jaded adult nerd that there is still plenty to learn, and plenty to be curious about.....even if it is just for the fun of it.
I've yet to find a single subject that you can't explain in a way that's both fascinating and educational. Thank you for sharing your expansive craft. Happy New Year to you and the crew.
Amazing all the projects you do "at home". I have several degrees and I haven't seen anything where you could have used my help until this project. No, not the lemoncello, although mine's pretty good. As a retired physician I do stitches "at home". So I got that going for me :) By the way, you started my new rocketry hobby. Thanks!
Don't feel bad, it just means we have some parallel skill sets. I've never actually tried to make lemoncello, sake or mead. I've got a batch of kumis brewing based on cow's milk (no pregnant horses nearby) it seems like it's going to be pretty good...we'll see.
@@TechIngredients Just read the wikipedia spot on kumis...those Scythians were a wild bunch:) With your oil you've got lemoncello in a snap. The zest of ten lemons would make four bottles...that might be a dropper or two...add it to two bottles of Everclear and an equal amount of concentrated sugar water. Put it in the freezer and you're done.
I made a hot sauce with a lemon. In the recipe I made (I didn't follow any set recipe), I removed the zest of a lemon and put it in some rum for about 24 hours (though, it may not have technically be enough, I blended everything at the end with a hand blender). The point was to avoid heating the oil too much. I added the rum/lemon zest mix after I finished cooking the sauce. With the juice of the lemon and the zest, it ended up having a great lemon smell and flavour. Of course I added other ingredients, to round the flavours into something interesting (like a little bit of garlic, some maple wood liquid smoke and some maple syrup artificial flavour concentrate, white vinegar (this isn't a recipe where you want a "fancy" vinegars), salt and sugar (don't put too much sugar as to make the sauce sweet. Just enough to complement the lemon juice, but not too little as to barely have any sugar... it's almost an equilibrium where too much would make it too sweet and too little would leave the sauce too much on the salty side)).
I would suggest that you use mini muffin or regular muffin pans to freeze the lemon juice, than store in freezer bags or Tupper ware containers. This way you can simply remove and thaw the amount you need at a particular moment.
When life gives you lemons, add some sugar & brew some alcoholic lemonade! eg: en.wikipedia.org/wiki/Two_Dogs Alternatively, demand life take back the lemons, and burn down life's house! ua-cam.com/video/ELkgiJD9KuM/v-deo.html
6:49 Let me overanalyze this situation as a similar cut happened to me recently: I think this occured when I switched from a dull everyday knive to a very sharp one. I guess as soon as I go into autopilot (doing a repetitive task) my muscle memory kicks in (beeing used to a dull knive). So I use more power then nessecary to make the cut and at the same time I am less defensive in my hand position, as that is normally not an issue.
The opposite has also happened to me, moving from sharp knives to a dull one, the knife didn't bite and glanced and I stabbed my finger. Always start slow with tools you're not used to
Exact same thing happened to me recently, nice new knife + old muscle memory = lots of red stuff everywhere and a really sore finger (no stitches luckily)
Lemon oil did wonders for kidney stones for 3 of my family members. The Dr had nothing to test to see what the stones were made of. It powdered the stones. Thank you. I am a new sub great information. 👍
Spectacular video. Essential learning. Absolutely love your channel, perfectly produced - you never need to skip ahead, always rewind and replay as your content is described perfectly: technically, simply, and succinct.
The only time I ever had to rewind on TI was with the explosion/recording one, trying to get a better look at the different angles. The rest has been perfectly edited, or didn't need it.
Great video as always! I'd like to add one area of application you just hinted at when you spoke of scented candles--the limonenes are among the few (and certainly among the least toxic) solvents for waxes, so they are great for cleaning ski waxes and klisters, as well as functioning as carriers for boot dressings. Rather than using nitrogen to exclude oxygen from a stored liquid, I've used argon, which is available in spray-paint sized cans from tool and paint stores (like Lee Valley in Canada). Just a tiny shot is all that is needed to exclude oxygen, because argon is so much heavier than air. Works great for white wine, too.
Wonderful and inspiring. Me and my wife came to making syrups for cocktails (such a phase in relationships), and after this video I'm up for oils. You guys really influence the audience and I definitely like the way it's filmed. Thank you!
I have a very productive Meyer's Lemon Tree in my greenhouse in Tacoma Washington USA. It produced 8 and a half dozen full size ripe lemons a month ago and the tree is getting bigger. I hope to have hundreds of lemons next year.
That's a good ouchie! For lemon juice in a fresh cut, I think Alex was very restrained, I would have been demonetised for at least 2 minutes! The Limoncello could have been used medicinally, it's rather nice :-D
Amazing video! I have orange trees and run the peels through my still. The leftover hydrosol is what I use to proof down my rum. We juice the oranges, distill the oil, use the hydrosol in home made rum and the leftover mush composts in a fraction of the time whole orange skins that eventually makes its way back to the gardens and orchards. Everything gets used
Not recommended per se: I am in love with superglue first aid for cuts like that. The shelf diy stuff 'cyanoacrylate' is not ideal because something something toxic...but if you don't have access to dermabond (uses some other molecule than cynanide-ish) it is fantastic for emergency first aid. Only time I've ever truly sliced my hand open was chopping a lemon (irony) - and I closed a ~1 inch gash in my palm (no tendons or muscle) with superglue. Immediately stopped bleeding, and healed without a scar. Magic.
I am sorry, but you are very wrong about superglue. Actually, you're "not even wrong", which is worse. It's not about cyanide or no cyanide, and the medical grade cyanoacrylate glue is octyl cyanoacrylate based, instead of ethyl2- or methyl cyanoacrylate. Besides reducing the sting and being manufactured to meet medical certification standards, and being way more expensive, it's still superglue. Anything deeper than a couple milimeters and you'd better avoid trying to diy it outside of life or death situation where blood loss management comes before infection or potential nerve damage management.
Same. I recently found that Amazon has 10 tubes of butyl cyanoacrylate (medical/veterinary grade super glue) for under $20. The stuff cures almost instantly on contact with skin, making it great even for cuts that are still lightly bleeding.
I wonder how well this would work with lemonbalm. It's a plant that looks identical to and grows the same as mint, but smells exactly like lemons. It's very easy to grow, especially with constant access to water like in a self-watering planter box.
Always curl your finger tips so the side of the French knife is rubbing against your knuckles. Just don't raise the knife edge up-to or above the knuckles, and it then becomes very difficult to cut your fingers.
I've had a lot of experience sealing up cuts with cyanoacrylate adhesive. Even somewhat deep or jagged cuts (I recently got a bad one from a hack saw) seal up great if you can temporarily slow the bleeding with a rubber band or tourniquette. Amazon has 10 half-gram tubes of Butyl Cyanoacrylate (medical/veterinary grade skin glue) for under $20. It sets almost instantly on contact with skin, making it great even for cuts that are still lightly bleeding. It wouldn't work for anything down to muscle or tendon, but it's saved me several trips to the ER.
Don't forget when holding shut can sprinkle baking soda on top to help the exposed glue set super fast to ensure it's not a big mess with it coming open in one spot and then you are stuck with a hard glob inside while still having to seal the opened part.
@@WaterspoutsOfTheDeep It bonds so quickly with skin that I've never needed to add baking soda. I usually wipe it with a plastic bag just after applying to remove the excess, and the remaining thin layer solidifies completely within 10-20 seconds.
@@Nuovoswiss I've used it quite a bit underwater gluing coral for my salt water fishtank over the years. The issues I'm talking about come up gluing wet surfaces specifically. If the bleeding can be controlled and the area dried or slightly damp I can see it being significantly easier to apply. For open wounds that can't be closed boron significantly speeds up healing. There was a study done at a hospital where topically boron sped up healing of deep wounds by 2/3's which is unreal. 5mg "***elemental" boron added per 1ml of the topical product. This includes common household borax(with no additives). I sliced off the tip of my finger with a mandolin making thanksgiving food and tried the boron for the first time only a few times since I used a hydrocolloid bandage and only changed it once a week since they are left on and last time time I put on a new one the tip was almost fully regrown to my shock. It looked at first like it was going to leave a big concave indent. Just my anecdote. I used a ICES PEMF machine too since I already had it which likely helped, took away almost all the pain in a matter of a day or two, but even now still really sensitive. I couldn't even put on a hydrocolloid for first few days because it wouldn't stop bleeding like crazy so had to just have a pressure bandage on to stop the bleeding and it eventually did thank goodness lol.
Very interesting video. I have been in the chemical industry for 45 years. My specialty is distillation and I have experience with phase separators! Thanks for all of your excellent videos.
I was an operator in a natural gas plant for a few years and there are reflux stills all over the place in a refinery. Reflux stills and absorption towers were every where for different hydrocarbon process streams. I always found the principle of a reflux tower interesting to operate. In fact, all the different processes were interesting to operate. It's neat seeing a still operate clearly like this.

I have one. It's useful as a shielding gas for welding.
@@thomaslaparnestudenthbhs6439 I'm sure you know this, but for anyone else who reads this, argon works slightly better than nitrogen, but is way more expensive.

Top tip for storing liquids and minimising exposure to the air... Glass marbles.
I used to do this with wet film developer chemicals. When you've used some of the liquid from a container, instead of trying to find and decant it into a slight smaller container, drop clean/dry marbles into the container until you get the liquid up to the top again. Then screw on the cap.
That is a super idea!
I've honestly never thought of that but that's brilliant, thanks for the tip
That's a really good tip for something that you're using on a regular basis. Kudos!
drop marbles in carefully if you have glass bottles or C3H5N3O9 ;)
And what if you’ve lost your marbles?
Another very absorbing video. Even though I may never reproduce one of your experiments, exactly, you present ideas and knowledge that is transferable to other areas of examination. Your demonstration of issues and the stimulating content are far more interesting than your contemporary UA-camrs. Thank you for your dedication to quality.

Educators who manage to entertain are such an awesome breed of human. Thank you sir.
From one Alex to another, don't feel too bad about that cut on film for everyone to see. We appreciate all the blood sweat and tears that go into these videos, a little more blood this time but you know it happens... I hope you heal up quick! And I always appreciate your roving hand carrying shots keep up the good work.
As another Alex...... "I concur!"
Learned slowly how to cut things really effectively and fast. About 3x faster than the spouse and she isn't slow. Knives are nice to keep razor sharp and pro chefs tutorials about cutting things like the onions are way too complicated. Cuts make the master bro.
Alex in Spanish agrees.
ohh I assumed the reason he did not want to show was due to monetization, since youtube is pretty strict with blood etc. I know a few science youtubers that have gotten into truple due to this. And its a sad reason to have your channel closed to (even if only for a week or 2)
Big up all Alex's 🤛
I enjoyed this immensely, I worked for A. M. Todd Company 1984-1995, an Essential Oils Brokerage. I was in the Jefferson Oregon Field Office. My primary function was delivering 50 gallon drums preseason to the peppermint growers, picking them up when filled with 400 pounds of oil, off loading at warehouse, dewatering, weighing, and inventorying them. When shipped out each barrel was hand loaded onto a semi trailer with a drum truck. 100 per semi trailer, makes me sweat just remembering! 80% chance when you brushed your teeth I handled the oil that flavored your toothpaste 😁 Great Video, Thank You!
im not saying the oils are a cure all but something's it works and its cheaper, colds/shuffy noise's ect. works wonders or at least for me and it's somewhat good for asthma ect. or cleaning up the house/car ect.
I was too young then to be able to face peppermint toothpaste.
But I'm sure my mouth would have thanked you.
Hand loaded with a drum truck? Where did you get a drum truck with hands?
We used to supply Bitter Lemon Essence to Schweppes Nigeria, an about this time of year in 1990 the packing staff reported someone had switched the lemon juice barrels from rectangular steel ones to more barrel-shaped plastic ones, nobody'd noticed. The consignment had to go (Christmas eve), so they used them anyway. What was designed to fit a standard 20' container did - with packing!
During the journey, it evidently shifted. On arrival, we had a report back, that the doors had become self-opening, and the f##k-truck driver had been deluged in lemon juice! Well it was puetic...
@@JelMain I was fortunate that the shipper we contracted with understood the "Special Assignment," of moving our product. They would send the same man nearly every time. His name was Elliot, we would take lunch together after I loaded the trailer, we became friends and I stayed in contact with him over the years until he passed away. Our loading dock was like some kind of demented test for a driver to back into, over the years I actually had several drivers give up. 100-102 barrels per load averaged 500,000.00 USD in value, depending on market. Cheers Rahere! Merry Christmas!

"Are you feeling dizzy" may sound like a funny question to ask, but some people really do pass out at by the sight of blood, and sitting down might help prevent a falling injury that could be very dangerous to someone's head. It is a good to be aware of this possibility.
Yep. And he's a doc ;-)
This almost happened to me when I cut deep into my finger with an exacto knife. My vision greyed out and I got tunnel vision, luckily I didn't collapse as I was standing at that time.
@@Ergzay It can happen quickly but if you ever sense that again, sit down quickly to reduce risk of injury. I've felt faint a time or two after an intense work out, and experienced that grey and tunnel like vision for maybe 5 seconds or so. I cant tell really, because fractions of a second seemed like forever. I think I pushed myself into a hypo-glycemic state, and I remember passing out once as a young child, and now as an adult I sometimes feel really nauseous, dizzy, clammy cold skin and turn a little green. Symptoms not uncommon to very low blood sugar.
@@kreynolds1123 I have had many seizures, and I have learned to very quickly, find a stable place to anchor my hand, as I carefully, lower my body to my knees. If I am still conscious at that point, I find a safe place on the floor, to put my other hand, and get my head to a place away from anything that could cause damage. All this in about three seconds, but very careful and aware, as I am looking for a way to safely fall, as the seconds go by. I don't know why, but for some reason, once my legs are bent, and I am kneeling on the floor, my head gathers awareness faster than if I were to try to tough it out on my feet.
@@Inertia888 kneeling I belive raises the blood pressure in your head a bit. I have no clue if that's related your clearer thinking or not. Then maybe there's a connection between blood pressure and some kinds of seizures.
As Your knees bend, it queezes some blood up. It limits some flow to your feet. And if your heart is maintaining the same pressure, some of that flow is redirected to your head.
Your teaching style is a stream of consciousness exercise. You simply explain what you are thinking as you go through an experiment. A great storyteller
I wish Alex a speedy recovery. I had a similar injury and can attest to the fact that it's not fun. While I swore like a sailor, Alex acted calm and professional, especially given the fact that he was cutting lemons.
That was a freakin sharp edge so the wound will come together fast.
It's jus a cut.

I love how you keep mistakes in the footage.. keeps it honest and transparent and Alex handled it like a champ.
This video is a good demonstration of the importance of proper knife handling techniques, which become more important when using sharp quality knives. I harp on my kids about keeping their fingers curled when cutting, and this is exactly why. A friend of mine cut the tip of her finger off doing this, went right through the nail and everything. I’d say he was rather fortunate he was not using more force while cutting.
Feel better Alex! Heal up quick!
Also, thanks for showing us the the cut and the blood. It adds realism to the project and allows us to understand that we should always focus on safety an attention with what we're doing in the lab. Cutting gloves next time might be a good choice ♥

Hope your assistant heals well!
Also, on a note of the knife accident, small tips on proper knife usage for those watching:
- Proper knife holding: hold a knife with the middle finger as close to the end of the handle as possible (middle finger can touch the bolster), and use both the thumb and index fingers to grip the spine (top part of the blade that doesn't have a cutting edge). Knives have their center of mass as close to the bolster (middle part between blade and handle) as possible, so this grip makes it so you hold the knife at its center of mass, which makes the grip more stable and firm. A quick image search on "proper knife grip" shows how to do this grip.
- Cat paw/claw grip: retract tips of fingers to hold the stuff you need to cut as if you had a cat paw or a claw grip. It's hard to get used to, but it's safer. The point is that the cutting direction is never going towards something that is straight. The search for "proper knife grip" should also show these grips.
You’re one dude who won’t have to apologize to his viewers. You’re an honest and good man, smart as hell too!
Interesting, as always. BTW: the chef's way to cut a lemon in half is to hold it between finger and thumb, creating an arch with your hand, with the axis of the lemon horizontal. Then you can safely introduce the blade of the knife, with no risk of cutting your fingers.
Way to hang on, Alex! "Yeah, I might need stitches, but let's finish filming. I'll just hold this blood-soaking rag to my thumb and keep filming while you keep on presenting!"
I gain so much from these videos. His ability to articulate in elegant and precisely direct terms the technical aspects of what are often quite complex processes shows his complete mastery. "Experts" of lesser intelligence often resort to 'high fallutin' terminology and more complex language to impress the listener with their supposed erudition. I am in awe of the scope and depth of his knowledge, of his communication skills and of his unfeigned humility. Thank you.
Thank you!
I hope Alex heals well and quickly! As always, excellent video where I learned some totally new things I can file away for use when a situation arises.
What a trooper. He's leaking fluid and has probably got a good inch and a half sized hole in him and he's got a camera getting close ups instead of going to get stitched up. About 8 years ago working at a hardware store I had someone bump into me while holding a hack saw at the work bench in the crowded receiving room. The blade gently tapped the back of my thumb along the knuckle along one of the creases and left most likely a single layer of cells intact because when I looked to check it I watched the skin peel itself apart and almost passed out where I was standing because I could see under the wrinkly semi loose skin. Tendons are effing gross. And I used to be a butcher, but it's different when your looking into your own body. It still makes me nauseous since there was very very little blood.
How tf do u get cut by a hack saw? Thats like getting cut by a butterknife.
I'm reminded of a story from the classic book "Ignition!" by Dr John D. Clarke regarding d-Limonene. He worked at the Naval Air Rocket Test Station (which later became part of Picatinny Arsenal) and for a time in the mid 40's they shared test stands/facilities with Reaction Motors Inc.
During this period the people at RMI were testing all sorts of unconventional concoctions for possible use as rocket fuels, and one of these was d-Limonene burned with WFNA (white fuming nitric acid). During this part of the program the area around the test cells was "blanketed with a pleasing odour of lemon oil", an occurrence so far removed from the kind of aromas usually generated by experimental rocket fuels that Clark felt it worthy of noting in his text.
Thanks for another interesting video!

Off topic, but after seeing your series on epoxies I though to would be cool to see you tackle bioplastics. An hour or two of you guys talking about the core principals of bioplastics while running experiments on different formulas and how different amounts of this and that can affect the final product sounds like good entertainment to me.
From what I've seen on bioplastics is that they are made using non-petroleum sourced materials but end up still being plastics that have the same issue with biodegrading that traditional plastics have.
The various bioplastic alternatives for drinking straws explained. I hate paper straws.
Yes please! One of my goals is to sustainably source all of my resources. Considering how much we use plastic this seems essential.
(No essential oil polymer joke intended.)
I would really like to see this too. I've dabbled in trying out different approaches and recipes but I'm not as organized or methodotic as these fine gentlemen.
bioplastics are a plage for recicling ... try to mix Polyethylen and some Polyethylenlike biodegradebal plastisc and make some watertubes ....can u imagine what happens ? a company i know did go bankrup becouse they sold whitout knowing partial biodegradebals house water pipes .... and by the way nature alredy takes care of oure problem of plasic polution ... ther are more and more bacterias that can use everyday plastis and use encyms to breack them up ..... hmmm i see a real problem for my job future what if this bacterias did ther job to good ? we realy need stable plastic for our society :)

Hi, TI. I guess that is what you call, "The show must go on." I hope everything healed properly. Thanks for sharing! Stay Healthy!
I am shocked that I just discovered you, but I am super happy that I did.
Great instruction, even talking about the energy it takes to turn water to ice 144BTU pr lb, and the heat in the steam 970BTU pr lb.
In the Refrigeration and HVAC course I took, that was somewhat mind blowing. It only take 180BTU 1 lb of water to go from 32F-212Fbut 32F 1 lb of ice takes 144BTU to become water and 1 lb of 212F water takes 970BTU to become steam.
I saw that cut coming the first time I saw him cut the lemon holding it incorrectly. BTW, superglue is a great instant stitch for minor cuts in a pinch. There is also liquid skin makes a nice addition to a first aid kit.
in his defence, he's a kid and most kids don't know how to cut vegetables and hold knife properly. But he handled himself excellently after injury though. didn't panicked, remained calm and kept chugging forward with recording without a single complaint
Or butterfly closures/stitches. Do a pretty good job for clean cuts, if you can stop the bleeding temporarily enough to stick it onto your skin
i was once told that superglue (krazy glue) Cyanoacrylate was made to glue skin together for use by medics in vietnam
Superglue? It's toxic in the blood stream, innit?
@@anonymousarmadillo6589 Not any more than rubbing alcohol is.
You can also use sugar to extract citrus oils from the zest to make what is known as Oleo-Saccharum. You could have then used that citrus oil infused sugar in your lemonade to give it a complex flavor profile.
Only way to make proper lemonade in my book.
Grandma used to grate the zest of lemon and orange, then muddle it with sugar and put it in a jar and store it in the fridge. Never thought it had a specific name like oleo-saccharum
I love the people who try to learn me how to make lemonade and in the end I have learned a big bunch of "unrelated" stuff. Thank you very much indeed
I've just made a lot of limoncello a couple days ago! The lemon skins will stay in the alcohol for a whole month!! Hi from Italy 😁
Some days ago I harvested olives and I made fine extra virgin olive oil. All the suggestions you made for preserving the essential oil can be applied for the olive oil too. I found the perfect excuse to obtain a nitrogen cylinder 😂. Thank you 👍
Liquid Nitrogen can also be applied via Qtip to freeze warts, only reapply if after the scab sloughs any of the wart survived. Plantar warts however, should be excised from the side of the foot by a Podiatrist, because the roots are deep & scarring can hurt like having a rock in your shoe... forever (gasp).
It is usually a man that talks like this, and we always need to give so many reasons to get something to "play" with even if in the end we are doing something for the benefit of everyone else. Wives are so tough to convince. Good for you!
Professional chef of nearly 10 years here. Everytime I've cut myself you can tell how bad it is from the reaction. The not so bad just a little scratch cuts typically get some variation on every swear word and yelling possible. The truly bad stitches needed cuts typically get very calm, Gently place the knife down, and walk to the aid station. Hope he recovers quickly!
When trying to get those deep gashes to stop bleeding for either treatment at home, or to make a less messy trip to the ER. One or two wraps of electrical tape over the paper towel works fantastic at applying constant pressure. You can get about six to eight pounds of pressure per lair with electrical tape. Just keeps adding up. Be careful you don't cut off circulation.
That or super glue, but keeping the cut higher than the heart level lowers the pressure.
A the advice of a sparky. Plumbers just wipe glue on the cut. The burning running up your arm is the clean / sanitization power!
Don't worry it will peel off no problem.....
Super glue saves the day
While working on cars, a mix of axle grease and dirt stops the bleeding as well. Generally I use electrical tape in a pinch. I find two stroke oil mixed with dirt works fastest on bleeders. I used to work on snowmobiles and always cut myself on something. Grease, oil and dirt stops bleeding fast.
Pressure dressings don't need to go all the way around, just fold up gauze (or the cleanest substitute) over the wound and then pull on the tape after sticking it to the skin on one side so that it pinches the sides of the wound together when you stick the other side down. If you ever do have to cut off the circulation on an extremity though, you must release the tourniquet no less than every 2 hrs to let blood circulate some before reapplying. Just fyi.
I found you through all your solar videos and love all your content. Your astute, no nonsense way of going about things is so refreshing! Thank you for being an absolute wonderful teacher!
Thanks!
@@TechIngredients really love the show. Would be great to see your thoughts on building a high powered ultrasonic cleaning bath.
This is one of those prime examples of why knife skills are important. When you handle a chef knife properly and use the proper technique the odds of this happening are severely reduced. Pinch the spine of the knife just after the handle so that the knife can't turn or spin in your hand, and rest your finger tips straight down onto the stuff you're cutting with the side of the knife against the flat of your knuckles. Almost impossible to cut yourself like that since your finger tips and thumb are never in position to be cut.
Look up a picture or video of how the pros do it and never slice your digits again. It's worth it. Plus you can go faster and more accurately. Sucks that happened in the vid but hopefully others will take the two minutes to educate themselves. Excellent vid, fellas!
Agreed and thanks!
I've had several of those 'marginal' cuts heal perfectly by running the coldest water available over it until the bleeding stopped, a dash of alcohol and then more cold water, and as quickly as possible closing the wound under pressure and absolutely, positively not disturbing it for a day or two. Butterfly strips are good, even under a band-aid, and I've actually splinted a finger before just to avoid any movement.
I remember one particularly clean cut managed to stitch itself back together in less than a week, though I still taped it to make sure it wasn't going to pull open at some inopportune time.
The pressure is the important part. Some plasma seeping is alright, since that is where the platelets are. Firmly pressing at the interface point, to stimulate the glue effect. And...if it hurts, well, don't do that...
It was hard for me to see the exact angle and depth of the cut, but superglue works great. It looked deep enough that there is not going to be a flap of skin that will eventually die and dry up (i hate those kind, usually due to a shallow slice, where the top surface doesn't have enough bloodflow to reattach, and it turns to leather and catches on everything). Usually just gotta wait for it to die, which protects the underside of the slice that is raw, by the time the lid dies and dries up, it's time to cut it off as the underside has a layer of new skin by then. Paper thin and pink, but then ya can chop it off. I hate those low shallow cuts on fingers, always catch on pant pockets.
Until a few years ago I never bothered with cleaning small cuts. I’ve worked in metal fab my whole life so I’ve had a few. A little electrical tape or duct tape and I would just keep it taped for a couple weeks until it grew back together. But a few years ago I had a sharp metal burr poke through my glove and into my left middle finger. It was literally the size of a pin prick, it didn’t bleed very much. I put a bandaid over it because we had them handy and went back to work. A few hours later my finger swelled to 4 times its normal size and turned red. It felt hot and I could feel my heartbeat in it. My boss sent me to the emergency room where I received antibiotics through iv. I still wasn’t taking it very seriously and felt like everyone was making a big deal out of it. Then the er doc told me that I had a good chance of losing the finger. That night I had a fever and I have never felt so awful. By the next day the fever broke and the swelling went down. I got to keep my finger. I take cuts more seriously now.
SUPERGLUE is the charm for clean sharp cuts! leaves a little scar, burns like hell but u stop bleeding instantly and are able 2 go on... that´s what it was invented 4!

Suggestion: Freeze the lemon juice in ice cube trays so that you don't have to thaw or partially thaw an entire gallon.
It’s a great suggestion. But something tells me when these guys thaw lemon juice, they do it at scale.
I think that's why he said he was only filling it 2/3 full. He can thaw it, add water and sugar, and it's ready to drink. My guess is that he's done this before and knows the ratios that produce lemonade to his liking.
95 percent of the world use Metric/Celcius and being from Aus I really appreciate how you mostly use metric. Saves me from having to pause the video and google a conversion every minute or so 😋
Obviously the US are slowly transitioning to Metric, but I can see how this can take time..

orange oil(cheaper to buy than lemon) is my 3rd most use solvent for cleaning, right after water(with soap if needed) and isopropyl alcohol. it will pull the glue from stickers and labels off of things fast and smells great. also perfect for removing pine pitch from your hands.
Limonene is found in lemons, lime and oranges and is the active ingredient.
Orange oil is also great for cleaning greasy hands, after working on the car.
If you really want a really good degreaser and an excellent solvent for cleaning glue, then try Turpentine. It's the mother of all terpenes the same family of chemicals that include limonene and Tetrahydrocannabinol.
I think there is a famous brand that has sold straight orange oil for cleaning just for this purpose. If only someone remembered the name...

Yep, as someone with a lab of unbelievably sharp things, I concur! I had the unique situation of spending several years and countless $$ on microscopy equipment, And then another room/section of the lab a separate business… of woodworking, Specifically hand tools, and countless years chasing the perfect edge.
It was only a matter of time until I was testing ways to get the sharpest edge possible no matter the cost.
Damn curiosity!
So I’ve had my fair share of bone deep blood gushing cuts. Where a simple slip can take off a portion of the finger
Finally I just quit going to the emergency room and keep a “stitch up kit” in my lab. Also, medical grade super glue which is what they used on me most of the time. My cuts were always to the bone or close, and in areas that hardly could be stitched. So a little investment in the proper supplies and materials is a good idea 😂 and practice before hand so you know what to do when the shit hits the fan, and you don’t contaminate an open wound or a missing finger. They’re all in my lab has always been, Hospital only when body parts start hitting the floor. Unless I turn into a serial killer… Which is looking more likely by the year… That rule shouldn’t be hard to follow.
Was letting a good friend borrow a piece of equipment for a big job, because his failed the day before. $18,000 worth of surgery and dental work later, Sometimes I wonder if I will continue to fine his teeth fragments on the floor when I do a big lab cleanup. Worst non-lethal accident I’ve ever seen. But it really wasn’t anyone’s fault because the building was being remodeled and the power cut in the middle of him using this machine. Even with the backup lights, the loss of RPM and such a sudden change in motor torque, he didn’t stand a chance.
Be careful out there folks
There are different versions of medical glue out there. If you want the best option for your dollar, or just can't get a hold of the proper medical glue that would be used in a hospital, then try out vet bond. It is safe for human use and much safer than the little tubes of "medical" glue that are found on places like Amazon. Only downside is that since it is used with other closure methods it is a bit weaker.
The little "one time use" tubes you can more easily find seem to work fine so there isn't anything wrong with them. Other than the fact that they're super wasteful since the packaging isn't designed for multiple uses and you don't need a full tube a lot of the time. I also question how sterile they actually are and the overall safety, but if I had no other glue around I would still use them.
those emergency UPS / BPS are essential with stuff like that... ouch

@@Santa-614 Believe it or not it was a tablesaw. I’m a machinist and tool and die maker by trade so I’ve worked around a lot of lathes and Mills and you’re right. They can do some terrible things.
I’ve always used the best I could afford and I had just purchased a “saw stop” brand table saw. They are claim to fame is that they can immediately lower the blade within a split second when it senses contact with skin. So they literally are 1000 times safer than normal table saws… Which are usually the most dangerous tools in a shop. I said it all several times and the wound on my finger was so minor that it didn’t even draw blood. It’s within one millionth of a second the blade disappears below the table, because usually if you touch the blade even just a little bit, it will pull your hand into it and you’ll lose at least two or three fingers. A good 10% of the woodworker so do it professionally and have for years are missing several fingers from tablesaw accidents
But the building was being renovated, it was a huge industrial incubator for small businesses. I was in the middle of a large batch of guitar finger boards that I was cutting on the table saw. I always lock my shop doors when cutting….. so no one could sneak up on me when using equipment like that.
But the maintenance man let in a good friend of mine without me knowing, which was no big deal and a normal thing because I always had people in clients visiting. And sometimes I would have the music cranked up pretty loud and it was a huge warehouse type shop. So you might not hear someone knocking.
He snuck up behind me without me even realizing he was there, and he was standing directly behind me DIRECTLY IN LINE with the table saw blade.
The maintenance crew doing the remodel accidentally cut the power for a few seconds, On the whole building. which reset the breaker in my shop and powered off the table saw. I was cutting extremely hard Ebony wood using a push stick, so not only did the few seconds of total darkness totally throw off my senses… But as the blade jerked and began to slow rapidly it quit cutting and it grabbed the fretboard blank… and push stick, throwing it right past my head … If you’re not used to big powerful tablesaws you’d be amazed how fast they can throw something across the room. They can throw a 60 pound billet of mahogany well over 100 miles an hour up against the block wall and break the brick
That’s why you always use a push stick with the table saw, so that you’re never in line with the blade and path.. it all happened so fast, there was so much blood. Immediately got him down on the floor because he looked like he was going to pass out, call 911, and helped him keep pressure on it as best as we could but without knowing the extent of the damage you don’t want to be pushing on somebody’s head to hard. I grew up in a family of doctors, forensics investigators, and Taxidermist.. So I’ve seen some terrible shit, mangled bodies, and awful injuries. So I knew it was not life-threatening. But it was still pretty damn bad and gruesome
We looked for his teeth over the next week or two, and even with insurance I paid about $15,000 for his subsequent surgery and dental implants. I felt so bad because he’s one of the nicest guys I’ve ever known.
The craziest part… His girlfriend was with him, they had just met a few days prior and it was their first date. He was bringing her there to show her my Guitar business because she was a musician… So it was literally like the first hour he had been around this chick. Now 15 years later they’re married with several kids. At first I worried that maybe the trauma had caused them to bond and maybe they shouldn’t have gotten married so soon. But they proved me wrong 😂
@@hullinstrumentsWhat an amazing story to read in a YT comment. Thank you.
Having used very sharp chef knives in the past, I learned very quickly to cut knuckles out instead of tips out.
Hope Alex heals up well!
imagine you have this man for your dad but you still dont know how to use a knife
I did this once, but I don't have knife skills, cut the tips of my knuckle skin off instead of my finger, on 2 knuckles. Was actually worse than just cutting my fingers as would keep splitting open all the time due to it bending all the time.
@@rdizzy1 I am in awe. I don't know how you managed that but that sucks. Normally the edge of the blade doesn't go higher that your knuckles
@@Metalrasputian If you know how to properly cut I would imagine so.

Sir, I’m really enjoying watching you go through your experimentation in real time. Your channel only came to my attention today, and this is the second one of your videos that I’ve seen.
I’m only part of the way through it, but I’m afraid I’ll forget to tell you that the water that you’re draining off from the separator, it’s not just water. It’s hydrosol.
It’s a valuable byproduct of your essential loyal production, and I think you’ll find you have a lot of uses for it if you want to look into it.
It is also helpful to flood the bottle with nitrogen just before decanting the essential oil. Nitrogen is only a tiny bit heavier than air, but it will remain in the bottle long enough to be displaced by the oil. It's a lot less complicated than the "nitrogen packing" demonstrated in the video.
...and blowing N2 across the surface for a bit will agitate the oil and get rid of some dissolved oxygen.
Next week, we make and test high performance cyanoacrylate for the application of closing wounds in lieu of sutures.
Speedy recovery, Alex!

For oils separation add a saturated salt solution. It will increase the polarity difference and speed up the separation process.
Or add a bit of anhydrous MgSO4 to the oil. It will suck water out of the oil.
would you loose a little bit of the oil to soaping?
@@byrdhartley9014 No, the essential oils are not triglycerides. And even if they were, you would need strong base to form soap. So, double no.
It actually wouldn't help , imo
@@byrdhartley9014 Adding a saturated solution of sodium chloride will not base it, and help drive off water which in turn would require less anhydrous magnesium sulfate.
Thought I'd pass along an interesting phenomena I discovered by accident. Added a little bit of Eucalyptus oil to the water in a cool mist humidifier tank which was made of clear acrylic plastic and opaque base plastic. Didn't empty tank after use and a couple days later found that the acrylic and base had been "etched" and to some degree melted or starting to dissolve. Essential oils seem to be pretty powerful! Hope this info can be put to some use. Interesting and well done videos. Thanks.
Eucalyptus oil is especially aggressive, I use it to strip labels (well, mostly the glue) off glass bottles to reuse.
Electrical tape is the best to keep you from leaking your electrons, just don't wrap it too tight, you would be surprised how much pressure a couple wraps puts on a cut.
Nop, I will not be suprised. :-)
Have used it with good effect many times. Often on top of a band-aid just to have less clue from the electrical tape sticking to the skin.

I did a similar thing when I was chopping rhubarb at age 17 (almost 40 years ago now). Alex handled it even a bit better than I did. 7 stitches and still a curved scar on my left ring finger. I told mom, "Y'know, maybe we SHOULD go to the hospital after all." 20 miles in 15 minutes later. Never saw Mom drive at 100+ before.
It's also worth noting that there's a few more interesting things that you can use lemon oil for, and it doesn't even need to be pure for some of them! Highlights include thinning finishes and paint[1], diluting into a great cleaning agent[2], and my personal favorite: melting styrofoam![3]
1: You can dilute Tung oil 50/50 by volume with technical grade d-limonene ( I'm not sure if food grade is fine for this ) to greatly reduce Tung's natural viscosity, making it easier to apply the thin coats you want to use.
2: You can mix a solution of food grade or technical grade d-limonene with water to create an impressively good cleaning agent, changing the ratio of Oil:Water for the desired strength ( I'd start with 1:1 and increase water if it's too strong ). Note, however, that the oil and water will separate over time, so you need to agitate the solution to keep the oil in suspension. You could probably add an emulsifier to the solution to help with this, but I haven't personally looked for what may be compatible in terms of shelf life and not leaving a residue.
3: Seriously, d-limonene and styrofoam are like a non-toxic version of acetone and styrofoam. You need a surprisingly small amount of it for the volume of styrofoam it can dissolve, too, so you can do fairly interesting recycling processes like filling a container with water, putting in enough d-limonene to cover the layer of water, and placing in styrofoam chunks - the styrofoam floats on the water, keeping it in the oil to break down, which then consolidates with itself, and once the new consolidation weighs just a little bit more it will sink into the water and allow new styrofoam to enter the oil layer for breakdown. The consolidated plastic is usually a bit gooey unless you evaporate off all of the remaining solvent ( the oil ). The final result are these weird little chunks of polystyrene, the plastic that styrofoam is made of, which you can use for shaping, or melting into a mold at a fairly low temperature ( like... 200f? )

I love your videos. I have a small 160 tree tangerine grove, just got and tried a still, and now have new things to try with next years harvest. Thank You
This is one of my more favorite recent videos from you! Simply because you arrived at a process the same what I did. I have all this waste material, what can I do with it?!
This my own impetus into the journey of distillation techniques. As always, I've learned a lot from your methods and will incorporate them into my own.
I could geek out on this process and discuss it for awhile but here are a couple quick tips of my own.
1) For Limoncello you want as much as the rind/yellow part and as little of the inner white part as possible. It makes it bitter. Zest it into cheese cloth and macerate from there. Trust me, you will notice the difference.
2) For oil extraction, try freezing the pulp first to help break down the cell walls. I don't run it through a food processor like you do so maybe this is redundant but I would be interested it makes a difference for you.
One minor thing: You mentioned low flash point oils for candles. I often use left over cooking grease but the low melting point (but perhaps high flash point?) tends to drown the wicks. I would love to see a video from you on this topic!
I worked as an engineer at a food packaging producer here in the UK and we used neat orange oil to clean the glue guns ,it's relatively food safe and dissolved the hot glue used to stick the induction welded membrane into the bottle/jar caps , that orange oil was nasty one drop on you're skin and if you didn't wash it off quick you'd end up with a sore patch for days that stank of orange till you'd had several showers... I got some in my eye once and Christ it felt like someone had driven a nail into my eyeball . Yes I was wearing safety glasses but a small drop still got in . I had a bright red blood shot eye for over a month.
I got so sick of the super strong smell of orange I still can't eat them.

31:00 Not everyone has a tank of nitrogen: You can buy a product called "Bloxygen" which is argon in a small can with a straw. After opening a can of stain or whatever, you add a shot of that before closing the can. It makes a heavy layer so you don't have to fill it up the void in the can completely.
Thanks for sharing!
One of the few ocassions that i can remember that the unsolicited presentation of a commercial product results interesting ;)
Only trying to be humorous, no bad blood at all, friend.
Gas mixtures do not form layers. Argon will not sit in its own layer, it will mix with the rest of the atmosphere in the vessel. If you want to flush out air, you have to add a minimum of that volume of argon.
I always give my oil based paint cans a shot of propane from unlighted gas torch before closing. stops the skin forming on top of the paint.
I always feel as though I have gone to a college chemistry class with your videos. Your methods of teaching and explaining what's going on make these chemical processes understandable as well as entertaining . You almost had me reaching for my car keys to go get a tank of nitrogen.

Thanks but actually, not even that...😋
@@TechIngredients Now I really feel useless:) Hope the weather's been OK for you.
Don't feel bad, it just means we have some parallel skill sets. I've never actually tried to make lemoncello, sake or mead. I've got a batch of kumis brewing based on cow's milk (no pregnant horses nearby) it seems like it's going to be pretty good...we'll see.
@@TechIngredients Just read the wikipedia spot on kumis...those Scythians were a wild bunch:) With your oil you've got lemoncello in a snap. The zest of ten lemons would make four bottles...that might be a dropper or two...add it to two bottles of Everclear and an equal amount of concentrated sugar water. Put it in the freezer and you're done.
I made a hot sauce with a lemon. In the recipe I made (I didn't follow any set recipe), I removed the zest of a lemon and put it in some rum for about 24 hours (though, it may not have technically be enough, I blended everything at the end with a hand blender). The point was to avoid heating the oil too much. I added the rum/lemon zest mix after I finished cooking the sauce.
With the juice of the lemon and the zest, it ended up having a great lemon smell and flavour. Of course I added other ingredients, to round the flavours into something interesting (like a little bit of garlic, some maple wood liquid smoke and some maple syrup artificial flavour concentrate, white vinegar (this isn't a recipe where you want a "fancy" vinegars), salt and sugar (don't put too much sugar as to make the sauce sweet. Just enough to complement the lemon juice, but not too little as to barely have any sugar... it's almost an equilibrium where too much would make it too sweet and too little would leave the sauce too much on the salty side)).
I would suggest that you use mini muffin or regular muffin pans to freeze the lemon juice, than store in freezer bags or Tupper ware containers. This way you can simply remove and thaw the amount you need at a particular moment.
When you are explaining the destillation,for me its like you are explaining the time machine to the littlle friends you still have ,really beautyfull.
When life gives you lemons, get insurance.
When life gives you lemons, add some sugar & brew some alcoholic lemonade!
eg: en.wikipedia.org/wiki/Two_Dogs
Alternatively, demand life take back the lemons, and burn down life's house!

I sell propane and propane accessories I tell you what.
Or super glue
Or you can get mad, and make Life take the Lemons back!
What if you r the lemon...
6:49 Let me overanalyze this situation as a similar cut happened to me recently: I think this occured when I switched from a dull everyday knive to a very sharp one. I guess as soon as I go into autopilot (doing a repetitive task) my muscle memory kicks in (beeing used to a dull knive). So I use more power then nessecary to make the cut and at the same time I am less defensive in my hand position, as that is normally not an issue.
The opposite has also happened to me, moving from sharp knives to a dull one, the knife didn't bite and glanced and I stabbed my finger. Always start slow with tools you're not used to
Exact same thing happened to me recently, nice new knife + old muscle memory = lots of red stuff everywhere and a really sore finger (no stitches luckily)
Me thinks I'll just get my oils off Amazon.
-a dull knife is more dangerous than a sharp knife
-always hold things from behind the knife
A dull knife is way way more dangerous than a sharp one
Lemon oil did wonders for kidney stones for 3 of my family members. The Dr had nothing to test to see what the stones were made of. It powdered the stones. Thank you. I am a new sub great information. 👍
Spectacular video. Essential learning.
Absolutely love your channel, perfectly produced - you never need to skip ahead, always rewind and replay as your content is described perfectly: technically, simply, and succinct.
The only time I ever had to rewind on TI was with the explosion/recording one, trying to get a better look at the different angles. The rest has been perfectly edited, or didn't need it.
Great video as always! I'd like to add one area of application you just hinted at when you spoke of scented candles--the limonenes are among the few (and certainly among the least toxic) solvents for waxes, so they are great for cleaning ski waxes and klisters, as well as functioning as carriers for boot dressings. Rather than using nitrogen to exclude oxygen from a stored liquid, I've used argon, which is available in spray-paint sized cans from tool and paint stores (like Lee Valley in Canada). Just a tiny shot is all that is needed to exclude oxygen, because argon is so much heavier than air. Works great for white wine, too.
Thanks for that tip! (and source for argon here in Canada!)
argon has many uses too eh (welding etc)
Wonderful and inspiring. Me and my wife came to making syrups for cocktails (such a phase in relationships), and after this video I'm up for oils.
You guys really influence the audience and I definitely like the way it's filmed. Thank you!
Great;
I have a very productive Meyer's Lemon Tree in my greenhouse in Tacoma Washington USA. It produced 8 and a half dozen full size ripe lemons a month ago and the tree is getting bigger. I hope to have hundreds of lemons next year.
Parents retired to AZ from WA. They sometimes feel like the neighbors give them away like zucchini some years.
That's a good ouchie! For lemon juice in a fresh cut, I think Alex was very restrained, I would have been demonetised for at least 2 minutes!
The Limoncello could have been used medicinally, it's rather nice :-D
Amazing video! I have orange trees and run the peels through my still. The leftover hydrosol is what I use to proof down my rum.
We juice the oranges, distill the oil, use the hydrosol in home made rum and the leftover mush composts in a fraction of the time whole orange skins that eventually makes its way back to the gardens and orchards. Everything gets used
That's great!
Not recommended per se: I am in love with superglue first aid for cuts like that. The shelf diy stuff 'cyanoacrylate' is not ideal because something something toxic...but if you don't have access to dermabond (uses some other molecule than cynanide-ish) it is fantastic for emergency first aid. Only time I've ever truly sliced my hand open was chopping a lemon (irony) - and I closed a ~1 inch gash in my palm (no tendons or muscle) with superglue. Immediately stopped bleeding, and healed without a scar. Magic.
I am sorry, but you are very wrong about superglue. Actually, you're "not even wrong", which is worse. It's not about cyanide or no cyanide, and the medical grade cyanoacrylate glue is octyl cyanoacrylate based, instead of ethyl2- or methyl cyanoacrylate. Besides reducing the sting and being manufactured to meet medical certification standards, and being way more expensive, it's still superglue. Anything deeper than a couple milimeters and you'd better avoid trying to diy it outside of life or death situation where blood loss management comes before infection or potential nerve damage management.
Same. I recently found that Amazon has 10 tubes of butyl cyanoacrylate (medical/veterinary grade super glue) for under $20. The stuff cures almost instantly on contact with skin, making it great even for cuts that are still lightly bleeding.
dermabond is octyl-2-cyanoacrylate
@@howarddyla9676 Butyl cyanoacrylate is also used in some skin glues.
I KNEW he was going to cut himself by the way he was holding the lemon. Super glue it, and get-er-done!
The amount of calmness after the thumb cut shows these guys are pros. You know what they say. The show must go wrong.
I wonder how well this would work with lemonbalm. It's a plant that looks identical to and grows the same as mint, but smells exactly like lemons. It's very easy to grow, especially with constant access to water like in a self-watering planter box.
For smell should work well
I agree with retag, it'd, probably, work well. Here, we have mint farmers and a few have their own distilleries [on a REALLY large scale].
it works great with lemonbalm, but the yield is kinda low.
For a second I thought His dad was being over protective with the knife.... and then lol. Happens to the best of us. Makes for a funny story
Always curl your finger tips so the side of the French knife is rubbing against your knuckles. Just don't raise the knife edge up-to or above the knuckles, and it then becomes very difficult to cut your fingers.
Thank you for sharing your vast knowledge with us. It's always a pleasure to learn from you and your family.
I've had a lot of experience sealing up cuts with cyanoacrylate adhesive. Even somewhat deep or jagged cuts (I recently got a bad one from a hack saw) seal up great if you can temporarily slow the bleeding with a rubber band or tourniquette. Amazon has 10 half-gram tubes of Butyl Cyanoacrylate (medical/veterinary grade skin glue) for under $20. It sets almost instantly on contact with skin, making it great even for cuts that are still lightly bleeding. It wouldn't work for anything down to muscle or tendon, but it's saved me several trips to the ER.
I did the same with a hacksaw, my 5 year old son was watching so I had to quickly hid it and the pain.
Don't forget when holding shut can sprinkle baking soda on top to help the exposed glue set super fast to ensure it's not a big mess with it coming open in one spot and then you are stuck with a hard glob inside while still having to seal the opened part.
@@WaterspoutsOfTheDeep It bonds so quickly with skin that I've never needed to add baking soda. I usually wipe it with a plastic bag just after applying to remove the excess, and the remaining thin layer solidifies completely within 10-20 seconds.
@@Nuovoswiss I've used it quite a bit underwater gluing coral for my salt water fishtank over the years. The issues I'm talking about come up gluing wet surfaces specifically. If the bleeding can be controlled and the area dried or slightly damp I can see it being significantly easier to apply. For open wounds that can't be closed boron significantly speeds up healing. There was a study done at a hospital where topically boron sped up healing of deep wounds by 2/3's which is unreal. 5mg "***elemental" boron added per 1ml of the topical product. This includes common household borax(with no additives). I sliced off the tip of my finger with a mandolin making thanksgiving food and tried the boron for the first time only a few times since I used a hydrocolloid bandage and only changed it once a week since they are left on and last time time I put on a new one the tip was almost fully regrown to my shock. It looked at first like it was going to leave a big concave indent. Just my anecdote. I used a ICES PEMF machine too since I already had it which likely helped, took away almost all the pain in a matter of a day or two, but even now still really sensitive. I couldn't even put on a hydrocolloid for first few days because it wouldn't stop bleeding like crazy so had to just have a pressure bandage on to stop the bleeding and it eventually did thank goodness lol.
@@WaterspoutsOfTheDeep Borax is very different from elemental boron. Some googling shows they used borates, not elemental boron.
outstanding content as usual, hope the assistant heals up quickly, and thank you!
Very interesting video. I have been in the chemical industry for 45 years. My specialty is distillation and I have experience with phase separators! Thanks for all of your excellent videos.
Thanks!
Hope your thumb heals fast Alex. I cringed when you did that. Great video Thanks... Happy new year all .... : -)
An uncalculated independent variable.

I was an operator in a natural gas plant for a few years and there are reflux stills all over the place in a refinery. Reflux stills and absorption towers were every where for different hydrocarbon process streams. I always found the principle of a reflux tower interesting to operate. In fact, all the different processes were interesting to operate. It's neat seeing a still operate clearly like this.
