Today we expose many different foods and materials to a vacuum chamber to simulate what they would experience in space. Find us on Patreon and our website: / techingredients www.techingredients.com/
You are a treasure. In the old world of the 90s you would have had your own Saturday morning science show. You're the PBS science guy for grown up millennials.
TBH this is how I remember the internet being in the late 90's early 2000's. You had extremely good education material, porn, weird stuff you can't unsee, and no real in-between. Back when yahoo/aol were young esp. Now, with meta-data being as it is and search engines working like they do, unless you know where to look the really solid educational material is hidden in a world vastly overshadowed by social media and distorted propaganda.
@TeamUSA - I'm definitely not a millennial. Think Captain Kangaroo. But this is one of the best learning channels I've ever run across. What an incredible resource.
@@oakmot5477 - Somebody has to pay for the production. I don't know who pays for this production - Patreon subscribers, I suppose - but he's got a great set up and produces top notch videos.
The food items may have tasted better if the weren't exposed to whatever came out of the phone, rubber bands and plywood glue. Next time I would suggest keeping food items separate from other materials. Looking forward to more!
@@madmatt113944 that wold be my thought. Once its volatilized and in the "air", I use the term air lightly since its in a vacuum, I would guess it would stay that way and be removed rather than condense back onto something else.
@@madmatt113944 in a true vacuum probably not. But in a small container where everything is touching each other.... I would guess that everything was contaminated with small solid particulates the moment the battery ruptured. But you are likely right about the rubber and glue.
Michael, we really can change that. You would be amazed by how much of an impact the concerted effort of just a few people can make. First, turn on notifications so you can view new videos as soon as possible after they go live. Then, make a bunch of comments designed to elicit responses from other viewers. Questions seem to work best in my experience, though there are plenty of others that also work. Finally, reply to comments made by others. The algorithm LOVES engagement and tends to push videos that have more to new viewers. That's why it's never a good idea to comment on videos that you feel are inappropriate. I hate to say it, but shorts are almost a necessity these days if you hope to grow your viewership. People scroll through dozens of shorts in a sitting. There's no need for them to decide to click on a thumbnail, and they usually don't mind spending 30 seconds to a minute watching a video from a channel they've never heard of. When they happen upon a short that interests them, they can and often do, visit your full channel with just two clicks. We had to abandon our channel shortly after we began due to a tragic accident, but I did a ton of research prior to that point. Now I have all this knowledge that I have no personal use for, so I've turned it into a hobby of sorts. If you decide to produce shorts, I would be more than happy to give you a few pointers on how to make the best use of them.
@@mustwereallydothisI hate this but I agree! Sadly it is how RU-vid works now and there are multiple channels growing just because of those community pools/questions and shorts
😆😂. “That won’t due. You don’t wanna do that”. This was super interesting. Thank you for always putting together such fascinating and educational experiments. I always look forward to watching videos on your channel, you guys inspire me!
You know what I really love about your videos? It's about putting meat in a vacuum chamber, which could have been a 5 minute "LOOK AT IT"-video, but instead you give us almost ten times that, and explain the entire setup, even go into detail on how individual aspects of your setup function. I never knew just how a diffusion pump works, I just knew *that* it works, and I thought that was enough... but watching your video, I discovered for the first time that diffusion pumps have that major advantage you mentioned, of not having any moving parts and thus not being very susceptible to degradation and failure. Thanks for always taking the time to do the science and engineering justice, instead of only providing bite-sized "highlights".
@@macswanton9622 no, no... it's definitely bite-sized. as in, small enough to be a single bite, referring to exceptionally short videos that half of youtube seems to love these days (and since its inception, to be completely fair)
Agreed. I don't know anything about the person who presents these videos but I would guess that he has given a lot of lectures. I could be totally wrong of course.
The chickens keeping you company were one of the best parts. You're definitely living life to the fullest. Cheers for nearing a million subs, a metric which pales in comparison to, and isn't representative of the amount of deep knowledge that's shared & well presented across such a diverse range of topics in the library of this channel. I hope many people are keeping archives of these videos so they'll never be lost to time.
Thank you! You and the team are unbelievably dedicated to thoroughly testing and researching every topic. I'm a 41 yr old science hobbyist that enjoys the level of detail and wisdom you painstakingly include in every recorded experiment. Keep it up!!
incoming thumbs down and comment removal. this channel and commenters like this are total dunning-kruger cases. copying and building apparatus from papers published many decades ago is not a science experiment. we repeat these experiments in first year chemistry/physics labs to learn proper lab techniques and how to present our findings for publishing. you don't stop there and just rebuild the same demos over and over again. we've been freeze drying for 134 years. experimental design requires immense creativity that is completely lost to "science hobbyist"'s like this. it's just sad to see the complete lack of curiosity and learning from tech ingredients, in contrast to someone like ben at applied science. instead we see how narcissists typically display way more signs of the dunning-kruger effect. the dunning-kruger effect leads them to release videos like "DID WE JUST MAKE THE WORLD'S BEST THERMAL PASTE!?" that completely fall apart the second it is tested by an actual expert in the field. because they didn't know enough about the topic to even properly test what they made. or building a speaker box somehow becomes "World’s Best Speakers!" in which we get the perfect quote "sometimes I think I'm smarter than I really am".
This is really some of the best science content I have ever watched in my life, I can think of no better science program being produced today that is as comprehensive while staying understandable and down to earth. I truly wish you had been my science teacher as a kid. stellar work, truly
I watch some of these videos as it is somewhat a pleasure to watch someone so methodical and thorough. Thank you for such informative and entertaining videos.👌
I've been watching this channel now for a few years now and the quality has always been top notch. I really like how y'all integrate the solutions to problems that y'all encountered when explaining the setup.
"if you're wondering, yes, i have diffusion pumps laying around - but i also have *points* turbomolecular pumps... just laying around" what an absolute legend
"No, it was not a tax-deductible trip." I would love to have you as my professor for just about anything. I have learned so much from watching your experiments, the way you show and explain how things work in the process is brilliant. I am learning so much. I don't know entirely when I will be able to *use* that knowledge, but it will come to me when I need it most. Thank you.
@@unlokiaot if he had tenure and could teach whatever he wanted. Could be called applied science class. The problem is professors do research and only teach because they are required to.
I appreciate your content. I always enjoy the way you nerd out over the process reactions taking place in the background of your builds / experiments, and how you became curious enough to make them. Very educational and interesting. 👍
Your channel: one of the rare few that gets a watch regardless of video Title, Thumbnail or Topic because I know it's going to be quality and interesting. Thank you for great content.
@@eddieelizabethhitler3259 it doesn't matter how likely, this is the definition of clickbait. They lied about what's in the video, nothing to do with space
@@nadca2 Fair enough, I respect pedantry, particularly in regards to science. Personally, I'm going to give him a pass because his videos never disappoint me.
@@nadca2it has plenty to do with space when they mimic the conditions of space to the best of their ability in order to find out what happens to a thing in space. Go somewhere else and be unhappy with life please.
"That maybe too sensitive for example we've held on to a couple of videos on advancements in crisper technology because of the recent global human malware event over the last couple of years". Brilliantly put in words.
Indeed. Maybe one day when they won't ruin their channel over it, they could do some experiments showing how chainlink fence is a poor barrier to sand. ¯\_(ツ)_/¯
Your site has broadened my mind and set me on tasks I never thought I would do, let alone achieve. Although I have been a subscribed user for the last couple of years, I have not actually responded with a thank you . I do so now and congratulate you and your family on creating an inspirational and motivating library of tried and tested practical information.
Love your videos. How about trying cold/contact welding? "Cold welding is the best process to use when fusing metal in such a volatile environment. It dates back to the 1940s and is considered a general materials phenomenon. In a vacuum such as space, two similar materials like metal fuse together through contact welding."
This channel is gold! 👍 You’re an amazing teacher. This has become my favorite channel. Keep up the great work! You’re so close to a million subscribers. 👌🏻
Great show!! I love how you treat everything with a scientific testing method. So many channels just say don’t do this at home, because they are taking huge risks.
This is definitely the most pleasant channel to follow. I love everything about it. The topics, the presentation, everything. Please keep up. Thank you very much
That's a great idea. The only thing it misses there is gravity. ARC welding too. Might require a larger chamber. The melting point of metals in vacuum could be tested.
I think the covalent bonds of the atoms on the surface of the metal are clean so it can rejoin reconnect in space "radiation and pure vacumn knocks off any unwanted atoms" arc welding uses a plasma gas from the electrode + arc, mig weld is basic molten metal pulled down to the surface , and tig is arc plasma argon. Helium etc with metal added to the molten pool
@@james2hackett870 I think in space you want to avoid venting gasses for such work, first because they create lift which is difficult to counter, and second because they require tanks that may not be easy to refill right now. I thought ARC was simply electric melting of a rod. If it requires a gas, then I suppose it's off the table. Thanks!
@@up4open763the gas is a shielding gas needing on earth in order to prevent oxidation of the meta on which you are welding. Shielding gas is not needed in a vacuum.
This was one of the most entertaining as well as always informative shows I've watched so far. The contrast between the technical, safety and engineering aspects against the letting the balloon fly, eating the beef and pork was absolutely epic. Thank you for all of it!
I'm an equipment engineer who works with vacuum systems everyday and you explained things so thoroughly yet concisely. Bravo. Testing the thermal insulation properties of Aerogel at various pressures would be cool and so would making and testing different forms of charcoal and activated carbon. I would love to see the differences in yields, porosity, and flammability based on the starting material. Also lol at "what are you going to do with it". My GF says that to me all the time
I sometimes wonder if DaVinci wife, mother, and girlfriends said the same thing. "That's all very interesting, Leonardo. But WHAT are you going to do with it?" The one I here most often is,"but you can already BUY that. " there is a certain satisfaction that comes from building things yourself.
I'm interested in how strong the wood pieces are having been "vacuumed" and if they have gained any weight back from absorption of water (and if that affects strength)
You are one of the best speakers I've ever had the pleasure of listening and learning from. What a fantastic teacher you are my friend, thank you for all your time and lessons! *Gratitude.
I love that I watched for 17 minutes without seeing the beef in the vacuum. Seriously, content like this is so refreshingly thorough compared to most of what is on RU-vid. I especially like downloading videos like this for flights. Thanks!
Right off the bat I want you to see how long the plywood maintains it weight reduction and how much strength it retained….and what you could do to seal it without adding much weight to it
This is incredible!!! Watching how you explain every bit and process helps me to understand a whole lot more, like how the lighting works to grow plants, among other things that flash through my brain on how this relates to a lot of other processes.😮
It probably dried completely. The surface was a bit burnt, but I don't see that it would make much of a difference. It seems that dry wood contains almost 20% water.
My question was related to the same thing about charcoal and this was his answer. Tech Ingredients Tech Ingredients 32 minutes ago It might take a lot longer, but the end result would be similar except that the vacuum charcoal would retain a little more energy potential because there would be zero oxidation during the process. 2
I would like to see unflavored and flavored Jello gelation tested, and compared to Aerogel. Would also like to see before and after weight comparisons, strength and burn test on wood samples. Great show, I always love to see Tech Ingredients in inbox. Thanks!
A test on the "remaining" strength of a wood structure after turning it into aerowood is probably interesting, as a light(er)weight wood alternative or how much the dessicated glue of the plywood still contributes to the structure
Also, does the effect last, or how long would it take for moisture creep back in, and how much over what time period? Would a sealant prolong the effect? If anyone else was thinking of it, the FAA can just weigh your ultralight or LSA whenever they feel like it as far as I can tell. So we need answers to all of these questions.
I am curious about the wood samples also. Maybe just a follow up comment w/ the before and after weights? Did you take any before measurements? Did they shrink perhaps?
Reminds me of watching Mr. Wizard many years ago--one of my favorite TV programs. Now I have an all new Mr. Wizard to enjoy! Great video! Some of my past research projects and experiments involved vacuum applications and frequent use of LN2 and dry ice. And my go-to supplier of materials was most often McMaster Carr--love that company!
One of the things I've been most curious about is how you've developed such broad and practical knowledge to be able to design these systems, which are often multi-disciplinary in nature, with elements of mechanical engineering, materials science, chemistry, etc. etc.. I would love to hear about your educational background, how much of your knowledge was self-taught vs. formal schooling, and what resources you consult while prototyping projects. We are all inspired by this channel and would love to learn how to walk in your footsteps!
Give a man 20 years and he can build a mountain. Age, my man. How long is college, 4 years? And 2 of those is useless bullshit the school tells you to be a "requirement"? List all those fields and give yourself a maximum of studying said field for 1 year each. Might not even take you 10 years to be on par with what he's doing right now.
im doing mechanical engineering most of what he said is basic physics 1 , of course he must be a phd or something like that, but generally if you pick engineering you will most likely encounter chimestry along the way because metallurgy and physics are all intertwined in the umbrella of mechanics engineering and mathematics ,which is the main star of the show in all of this. and frankly i am thinking of dropping out because multivariable calculus can go to hell. i like this guy he is a teacher you wish you had
@@gelo1238 Yep... but even then, it takes time. I'm 60 now (somehow, all of a sudden...WTF!) It's only because I've had so much time poking into things that I've got as far as I have. Plenty of blokes are brighter than I, and pick things up faster. Just stay curious and screw about with shit, it's not a race, it is its own reward. Perhaps someone will find my efforts useful after I'm done. If not, at least I've enjoyed the doing.
Another fantastic video! I love that when you go off on a tangent, that becomes as educational as the main topic. You are the single best science teacher on YT! Full stop. Can’t wait to see you get to 1,000,000 subscribers.
You mentioned it briefly, but aerogel would be interesting to learn about. Also a video on lab equipment itself would be really helpful for anyone looking to explore setting up a home lab.
@@revmsj overlapping layers of rubber will let the air out, but not back in. serving as a 1 way valve.. i suspect the external airpressure would just crush the aerogel. but if not you have a very light object.
I'd love to see a comparison of how different forms of lubrication hold up in a vacuum! My own investigation in this regard has unfortunately failed me
You have led a very interesting life to have the amount of knowledge it takes to make the videos that you make. We are fortunate to get a virtual look inside of your head every now and then.
I was just thinking as the pressure dropped the battery pack inflated and as it popped any volatile would spray. Maybe not so much from the plywood but as anything even micro bubbled onto the surface it would have some added energy and droplets surely travel further in vacuum. By the time the pressure had dropped there would be little to no airflow in any direction beyond the spray direction of the popping battery.
@@jimclark8845 Well, they're volatiles, they'd go away. Vapor deposition, now that's something to think about. I certainly did whilst looking at the strip of white deposit on the chamber lid right beside the battery.
@@Drmcclung I suppose all I am saying is I would not have even tasted something that had been beside an exploding phone lol. Needless to say it was an interesting way of freeze drying meat and I do wonder what it would be like re hydrated but without the phone.
2 things: 1. Maybe it would make more sense to fashion a reflector and shine the light in from outside the chamber to get rid of any conduction across the chamber 2. If you tie a knot in a deflated balloon and place it in there it should inflate itself. I’m sure that’s been done before but it would be interesting to see, especially alongside some supporting calculations of the size of the balloon vs pressure
The Problem with the reflector idea is that you would want as little material (polycarbonate, air) as possible between the testing subject and the light source. Reason beiing, that any material will absorb IR and UV radiation. Hence the glass removal in the first place.
Failure of elastomeric materials in vacuum may be caused by gas expansion rupture as they often have gas molecules permeated deeply into them. The first time you see an o-ring breaking apart from this effect is quite memorable. I made a short video I call 'Peeps in Space' where I pull vacuum on some marshmallow peeps making them expand, then rupture and ultimately shrivel like jerky when air pressure is reintroduced.
.. and yet the ISIS is up there in that environment for over a decade with all its o-rings intact. 🤪Oh.. boy... the bs people will believe about fake space travel.
Yet another outstanding experiment and video. I always learn something from every video of yours that I watch. Could you do comparison tests on the effect of UV/IR alone, Vacuum alone and a combination of both on the bonding strength of various adhesives?
I suggest you do a food only experiment so that it eliminates the chances of other materials/chemicals to interact with the food Great video as always!
Dude don't stop what you're doing because honestly you're making me excited about science again and I'm sure many others can say the same. Thanks for videos that illuminate discovering the awesome world around us. ☺
For the battery, I think what happened is that the sovlent evaporated - which is usually ethylene carbonate or a derivative of - which makes it also essentially freeze dried.
@@Hephera We know that the wood dried out. The question is did the water contribute to the strength of the wood, or more precisely, _how much_ did the water contribute?
@@Pystro , i think you have to consider the wood as a sponge, is a dry sponge stronger or not then a sponge that is soaked with water ? If you hit the soaked sponge quick enough with a sheet of wood or metal,the water need some time to escape, so the impact will be harder compared to a dry sponge, but if hit the soaked sponge very slow , the impact is almost the same compared to a dry sponge. So i think that the water does not contribute to the strenght of the wood. On the otherhand, the more water in wood, the more flexible wood can be if you bent it without breaking it, this also how wood is intensional curved and bent for making round objects in wood by steaming the wood, bent or curved it, and let it dry out in this shape. Once dry out, the wood is as strong as before. Grtz
Great videos, I'm a new fan. I'm building a methane generator and it's decent so I've been tweeking the variables to make it more efficient. People like you inspire people from all over the world to be curious and build more. Regards From South Africa.
Man you are smart and have so much knowledge about so many things and paired with a very competent and practical ability to design and build the parts you need, all i can say is wow. My mind is completely blown away by your abilities. Keep up the amazing work to give us extremely interesting videos and explain everything in a way that almost anyone can understand. Thank you very much!
It is videos like this and so many other interesting things you've done that keeps me coming back. Also why I suggest this channel to anyone and everyone I know that loves to nerd too!
Algorithms hide people who say certain things, and he's gotten way too close to those.= (ok, way beyond those at times). Also, he doesn't zany cuts, bold colors, and a horrible false smile all the time.
A couple of things: - monitor that wood over time and see how much water it reabsorbs. I think you’ll find in a humid environment the more porous wood regains more water weight. - you definitely coated those items with vaporized metal. You see evidence on the back wall, and you see differences in color and tone on the potato closer to the lamp. Re-running this with some way to shield from that ionized metal vapor might yield tastier outputs. You definitely came up with a new and interesting variant on the food dehydrator.
Love this. I also hate that feeling when someone asks 'but what are you gonna do with it?'. But that's how I went from high frequency vacuum tube plasma flame, to a plasma tweeter! Unless you have a dust removal system I'm unaware of, I'm surprised you are dry cutting glass with no protection for your lungs other than the face shield. Doing stuff like that a couple times irritated my lungs worse than smoking for a decade. I also really recommend getting a foredom hanging motor instead of a dremel. More power, no gyro motion when the speed changes, handpieces that can produce reciprocal instead of rotational motion for 'engraving', etc.
Fascinating stuff. I might've had reasonable grades in the sciences back in those days had I been exposed to such qualitative experiments and explanations. This highlights the utmost importance in having access to the right people for an education system that works. Thank you so much.
Another awesome video! You explain complicated concepts, making them easy to understand. Also, you have an amazing voice. Do you have a second channel with your voice that creates ASMR for relaxation.
Love your videos. Like @benwoo said, you are an absolute treasure. I feel like I learn more from one of your videos than I got from all my years of education, and am thoroughly entertained all the while. Keep up the good work.
A nice idea for a second channel would be your process of deep diving and engineering the projects. It's neat to see your demos of the finished application, but as someone that is interested in building, but struggles to put all the information together, it would be really cool to have some examples as to how a professional processes the information and brings it to life!
In terms of material testing, I remember hearing that during the Gemini program, when testing spacewalks, there was an issue closing the capsule door after Ed White returned to the capsule (to say nothing of the challenges of the space walk itself). The explanation I heard was "cold weld" which was apparently caused by the effect of vacuum on the aluminum doors and skin of the capsule. I've never really understood this, as evaporation of lubricant seems a more obvious cause. I have no idea how you could test this, but if you can, it would be fantastic!
@@lesliefranklin1870 I would suppose it has more to do with solar plasma and particles, though I guess the old two-metal battery might be at play in some fashion?
@@up4open763 I believe it's more closely related to the "Casimir Effect". And yes, dissimilar metals can also fuse together through the "Galvanic Effect".
That was a fun episode. Wood drying in a kiln takes so long to get the moisture content down, but your wood probably is in a state carvers or wood turners would love to work with. You are brave to eat the samples, because all of the palatable oils and flavors we enjoy would have been sucked right out, leaving a hard husk of muscle fiber. How about a carrot or a cell type veggie like an onion? It would be really interesting to try Lexan or acrylic sheets and other plastics to see how the vacuum and bulb effects them? You could do a series of episodes exploring what happens to all different thing we use or take for granted in our every day lives. I can't wait to see what you put in there next.
I would think it loses integrity the faster you dry it. Kilns make wood splinter, and good sawyers wax good wood for a slower dry. It would be interesting regardless.
The shell has pores, so a chicken inside can breathe - I imagine it would start to leak, until it ultimately cracks and then splits open *making quite a mess*
Thanks for a wonderful experiment. I really appreciate the full explanations of all the equipment and reasoning as well as the actual results. Amongst other reasons, I've personally found many of your videos inspire me to think about solutions in my own projects, even if the experiment or theory isn't precisely the same. Thank you both!
I have been marinating my beef for steaks and jerky in a vacuum chamber for years now….Turn a 24 hour marinade into 30 minutes with that room temperature boil
I really miss quality programing /Content like this! It reminds me of the Saturday mornings in the 70's explaining how and why things work. then we would spend the rest of the day running experiments in the garage or in the backyard (making a mess for Dad) it keeps the mind thinking. and experiments for a 10-year-old were always great fun with zero positive outcome for the experiment. Thank you!
I’m not sure if I understood very much of how the gases were being removed, pulled out or recirculated, but I’m wondering about how the phone/battery may have contaminated the meat... or is the vacuum itself totally preventing the transference and absorption of the one thing (battery) into the other (meat)?
I was about to post this same question. It would be good to just see how the food reacts on its own. There must have been some volatiles in the phone battery for it to expand like that.
@@joegee2815 agreed. I guess it might be the same difference though as freeze drying... where I think if he soaked them in water they might come back somewhat and be more edible. (Not that I know anything about freeze drying... but obviously his method here would kill anything that might pose a biohazard... other than maybe something like a prison disease, like mad cow... lol... could be his next experiment with it... making mad cow meat-safe!)
Could you please try different types of 3D print filaments in the space simulator. I was curious about which types of plastics would hold out better in space and if some would change colors. Thanks for the great content.
@@_skyyskater I agree about the PLA. I was just curious about the feasibility of creating a 3D printed craft in space ignoring the gravity and only focusing on the materials used ie various filaments. I am aware of the UV experiments but not both uv and vacuum also there are many new filaments.
@@TechIngredients I would absolut appreciate if you would run a few test on different wood. Might be a nice material for your exiciter speaker system. Would be awesome if it´s possible to run a setup that could contain large sheets or mabe just glue some slats together, later.
I'm curious on how time back in atmosphere would affect things, esp the wood. Maybe set the control vs sample on balance scales and see how they measure as they reabsorb moisture
I teach technical stuff and crafts to children in Germany and your hillariously divergent approach resonated with me somehow: The lessons my students remember the most are those where I teach safety but then get caugt up in the excitement, unwillingly throw all precautions overboard because I feel like a child again that just wants to see and fell what will happen together, if we just go further. The overenginiered Bulb-cutting in contrast to you eating raw Beef and exposed to every chamical condensate the phone gave off pushes my self-conciousness by a lot! Pleas be safe, thank you and keep it up!!!
Looking through the comments I see a lot of interest and good questions about the wood. If you do a derivative^2 video I am interested in the dimension changes if the wood as well! Love the great content! Thank you!
Love the video. my first thought when i saw the chamber was freeze drying and astronaut icecream. excited you went the other way and solar cooked instead :D
