I had so much fun shooting this. For those of you not used to seeing my face. I am massively concerned about the rise of AI channels on KZhead. They are currently flooding KZhead with AI written, AI narrated clickbait, and a lot of them are stealing our animations. I think faceless channels will become increasingly difficult to run in the face of AI content farms in the next 5 years. To combat this and evolve the channel, I'm trying to slowly diversify our videos. To add more personality, and to stand out in a sea of copycats.
Ok
Hello @RealEngineeriny i am an english speaker, but the video is in french for some reason. Since you started using narators, i cannot listen to your videos. Is there a way to change the language?
love your content, keep up the awesome work!

I love this video because it's basically a very informational shitpost, and is really out of place on your channel... And I would absolutely LOVE to see more like this! great work
I see a lot of creators make a second channel for content like this if they make it often, I've always liked that approach.
@@lethena6249 yeah I fucking love creators second channels for shitposts, helps remind me that they're just normal people like all of us that love shitposts too, there's just something so beautiful about shitposts, like when a game feels like an absolute shitpost like kingdom of loathing I fucking love it
This is science because it's recorded
@@tylerv9174 science and shit posting aren't exclusive. The best shit posts are from skilled and intelligent people, because even their shit posting is fun.
@@lethena6249 I agree that that'd be the right approach for this. Real Engineering has a specific format, and with Real Science it seems like that format is basically codified. It'd be great to have a second "Brian McManus" channel for stuff that's different. That being said it's his channel and not mine so whatever lol.
Idk man this might be the best video you’ve ever made.
I might agree this was super fun :D
Stupid, fun, and somewhat educational? I see this as an absolute win!
Best video
Yup.
stupid can be the most entertaining especially with smart people
More on-camera stuff! Loved this, it's fun to see creators try new things and I'm a fan of this direction
Uhaul rocket model when?
I love how disappointed you looked when you realized what the laser bell actually was. (To be clear I probably would have had the same reaction)
Spoiler alert.
I felt that.
I also thought they had some crazy cool laser activated bell....
@@oracleofdelphi4533 if you are worried about spoilers don't read the comments
My initial thought was that they had a complicated system of lasers that somehow activated a bell. I guess that's cool too though.

@@patrickhughes9094A lot of smart people have no clue what they're doing most of the time. You can't be afraid of not knowing what to do, or you'll never learn
@@patrickhughes9094wow, you insecure much? I don't see you working on a hypersonic wind tunnel
This is the engineering every engineer wants to do but doesn't get paid for.
Having gone to engineering school, I concur. Every engineer has had crazy and stupid ideas they'd love to explore but has no practical application. Or how they would solve any "problem" no matter how absurd or horrible. Probably every engineer has thought of how they would destroy the world if they had a reason to - most don't have a reason to but I'd recommend not giving them one. I recall discussing over several weeks with a college swing dance friend (if I remember right she was a forensics major - similar in this regard but even more dangerous) how we would go about flooding only the upper floor of the student union - not something we would ever actually want to do but our plans for how to carry it out were very detailed.
Cleaning out that vacuum chamber has to be interesting. Imagine finding a few NASA hypersonic vehicle prototypes that may or may not be top secret next to a model U-Haul and a cow.
Fluid and aerodynamics are interesting fields with even more interesting designs.
I am honestly shocked it survived the test and that the shock wave interaction was so wild yet stable through most of that. That was really neat!
Can't wait until the government weaponize it.
It did not survive the full test. It is splattered in million pieces inside the vacuum tank.
The highway lanes Not Just Bikes callout 2 seconds after I thought it was hilarious. Love it :)
What we actually need on highways is venturi flow. Half the lanes = double the speed.
@@appa609true, except for crashes. We just need trains
@@appa609i will settle for laminar flow. (No crashes, no cutting people off, no sudden lane changes) But also we need better options than just highways. The highways will always exist for military reasons, but functional trains would take so much pressure off of them.
Ew…a NJB cultist
It was obligatory, otherwise there'd be a hundred identical comments saying "Not Just Bikes would disagree."
We’re moving out of the house with this one 🔥
A comment of this quality deserves more likes
Renting a U-Haul just to tape down a tiny U-Haul inside it for a shot is peak fucking humor! Best 30-40 ish bucks ever spent for this channel. Edit: Thanks for mentioning Not Just Bikes, I was sitting here talking to the screen "More lanes usually doesnt result in go fast"
What if you had a De Laval lane architecture? Traffic can be modeled by fluid dynamics.
@@dongiovanni4331 yea in cases analogous to a De Lavel in traffic, the sudden shift from a constrained number of lanes to open road does increase speed. Just think about every time you've been on a highway that suddenly cuts down to single lane traffic then opens up.
@@travisbeagle5691 Traffic isn't quite fluid-dynamics like, mostly in that it follows discreet lanes, but there are certainly similarities. De Laval nozzle certainly is a good analogy though, as the "mass flow" is limited by the rate at which cars - at a "choke flow" velocity - go through the narrow spot, and "back pressure" - the density of cars or size of the traffic jam - before it doesn't have a huge influence on this.
Love how he was warned that if he wasn't careful not just bikes would come for him lol
@@Stevie-J How is it cherry picked data?, and how is it non-productive? Although i acknowledge we may value different things. Also, he might not be aware of not just bikes, so he'll just like "imma Ignore it because i don't understand it", intelligent people usually tries to understand the topic before speaking about it. (Also imagine how awkward it would be if he immediately interjects "what is not just bikes?" or "well traffic is a...", it will derail the conversation, especially infront of a camera recorded and published to a huge audience) And i don't think it's his field of expertise, (it's alright to talk about things you are not an expert in, i mean how can we understand things without discussion?), so i think he was just trying to explain it using simple analogies(like to an american citizen, i mean they are in america afterall with car centric infrastructure, they're bound to be more familiar with it), without looking at the complexities, Plus i think publishing high quality videos is already quite productive, atleast compared to commenting on youtube. Lol, In addition, the culture of production vs consumerism might be perpetuated either intentionally or unintentionally by the conflicting interest of companies vs consumers(ye unsustainable relationship), producers will probably spend less because they can create some stuff they use and can repair parts, and outright be independent. You can see how this might be a conflict of interest.😮
14:21 Excellent animation. Really helps me understand the real world implications.
I laughed so hard at the flip and explosion lol
Yes, this animation was crucial.
The animation of the UHaul with 4 rockets in the back being dropped from the wing of a plane caught me by surprise and had me laughing out loud in my office. Thank you.
Congrats on being the first person to say that sentence.
yeah this video is different but in a good way
“Periodically we get an undergrad to go fish things out” I love how undergrads really are just the younger siblings of academia
I would love to stick my arm in there. Of course, I am studying nuclear engineering, so I probably will not be sticking my arm into anything, other than maybe a rod control mechanism.
I'm surprised they'd have undergrads to it. To the university they're walking burlap bags with dollar signs on them, and pretty much useless for anything else. Grad students are the slaves used for this sort of stuff, and I could even imagine a professor deciding to take on a grad student in part because they're small enough to get inside equipment the professor needs serviced.
"...I'm not sure doing this on-camera stuff was the right call." I'm pretty sure everyone else watching this is as big a geek as you, Brian. I'm pretty sure we all enjoyed it.
"My friend Not Just Bikes may have uh.. some arguments"
Another great video, this is how it should be, taking the time and making the effort, going to these labs and create some real content, it gives the viewers the first hand look into what's going on and how it really works, KZhead is filled with videos where content creators google something then make a video with a voice over on it with some pics and footage.
No need to attack literally everything we have ever done 🤣
@@RealEngineering We want a new Bill Nye for every cool thing XD
@@RealEngineeringlol. The difference is your stuff is factually correct LMAO keep up the great work
@@Will-uf7jt Is that an attack on Lazerpig?
@@RealEngineering I don't know what I learned, but I'm excited.
For a "stupidest video", this had my jaw drop several times. I am absolutely floored by the Schlieren image on the U-Haul. I was expecting far more pronounced vortices, but this was crisp and gave a clear demonstration of where the forces are strongest. Obviously, U-Haul isn't going to get right on this data and make a hypersonic-ready truck, but it makes an extremely clear demonstration of how this kind of data can be used to help understand flight characteristics. And it's a reminder to watch your speed when driving a rented truck. Keep it under 5370 mph on the highway! U-Haul really missed out not sponsoring you on this one. 😂
What's perhaps most interesting - and surprising that this wasn't mentioned - is that the shock waves actually did pretty closely resemble the flow lines shown on the uHaul truck graphic that inspired it all. As for a uHaul sponsorship, I think they want to avoid encouraging people to drive their trucks at hypersonic speeds, though I know we've seen some people attempting to do so. A Nissan Altima would probably be a more relevant test for a vehicle people attempt to drive at hypersonic velocities on a regular basis. I hold that an Altima is actually a faster vehicle than a C8 Corvette - the C8 (driven by a retired Boomer) goes, at most, the speed limit, while the Altima (driven by a nearly-broke 20-something) goes 15-20 over, at least.
@@quillmaurer6563I think it's region-specific. Where I live it's the pristine Ford F150's clearly driven by someone over 40 that get driven 20 over on the highway. No matter who they have to run off the road to go that fast. Weirdly it started pre-pandemic with a lot of Texas plates (I'm in Missouri) and only a few local. Now it's almost anyone in that kind of uselessly oversized truck. As for the teenagers, the used car market here is mostly Ford, Chevy and Toyota, and the used ones have inflated so much that young drivers can only really afford those held together with duct tape and running on prayers and burning 15 gallons to the mile, so they aren't the racers they were when I was young.
@@Merennulli True. The Altima thing is more based on stereotypes, I've not actually encountered too many of those. The needlessly big trucks with super aggressive drivers is a major plague in Colorado as well. Certainly an attitude of rule-by-intimidation rather than obeying traffic laws. So maybe it's F-150s are faster than C8 Corvettes. I just know the slowest thing on the road are Toyota Highlanders and late-model Rav4s, driven by people who have zero interest in cars and driving and want to put as little passion into it as possible.
Chris Combs Is just as amazing of a professor as he is researcher! Was a pleasure taking a class with him
I used to work at U-haul hopefully the Employee at U-haul took a picture of the hook up before the customer pulled off , if not than that employee is gonna get fired.
I'm absolutely impressed that the little plastic toy didn't immediately disintegrate in the mach 7 air.
I enjoyed this "less polished" style. It felt inclusive and personable.
As an aerospace undergrad, I just love to come to this channel to see the stuff I’m learning about presented in such a fantastic way! Some of the last high quality content on KZhead
Don't misbehave, or you will be put into the vacuum tank. 🤣
Shout out to your animator Eli for superb work!
"I don't know what we learned, but I'm excited" Perfect summary of this video lol
No way! I was LITERALLY sitting behind a U-haul a few hours ago analyzing the very same diagram and having the same internal struggle thinking to myself, "Self, U-hauls just aren't aerodynamic." My work also crosses into hypersonics. What a great and timely video🙌🏼
6:19 I get the attempted analogy, but when you take into account induced demand and the fact that you have a limited number of choke points (off-ramps) on highways, adding more lanes doesn't speed things up long term. Once you have some level of knowledge of urban planning this is obvious; but the fact that " just one more lane bro" intuitively makes sense to someone with no knowledge on planning, is a big barrier to actually providing real solutions to urban congestion (i.e. public transit, higher density, reduced sprawl, bus lanes, bike lanes, increased walkability, etc.). But I do love how you brought up Not Just Bikes right after that lol
Have in mind that while adding lanes does not help reduce travel time for their customary users, it does increase throughput, meaning more people are able to use that route. The new users do get a benefit (otherwise they would go back to their previous route). So there is a net reduction in travel time, it's just that probably smaller than thought, and coming from a different side (slower alternative routes being used less).
@@MrTomyCJproblem with that is that highways cost a lot and use a lot of space compared to public transit
Wendover crew with Nebula money: Let's create a show where we play classic games with the entire world as the play area! Real Engineering crew with Nebula money: Lmao let's put a U-Haul in a hypersonic wind tunnel
"I Made a U-Haul go Hypersonic" You mean you actually got one to go faster than 35 mph?
That's what the new aerodynamic ones are for.
This was a fun mixup from your regular format. What I liked about it was its more personable and casual tone, less serious topic, and looser editing style. I don't believe it would be a good idea to totally transition, but if it was less work to edit and make, or you just enjoyed making it, I think it would be a great edition to the channel to do videos like these every so often
I LOVE that you're willing to do something stupid-silly, but also EXTREMELY interesting!
Supersonic U-Haul trucks, supersonic cows, metallic farts and a big Problem Solver 9000 (aka sledgehammer). This episode had it all! 😂😂😁😁🤘🤘
0:10 Only 10 seconds in and you managed to scare the shit outta me. I was sitting in front of my window and thought someone was knocking on it 🙃
I was in the class with the students that designed the part that you put the test material in!! It was cool to see it being made and the whole design process
6:14 like for the mention 👍🏼 Not just bikes must be triggered...
Triggered? Not Just Bikes is a friend of his, can't see why he would be triggered by getting a free shoutout.
@@swecreations triggered by the logic set by the head scientist.
@@sheevone4359it’s not logic though and traffic engineering isn’t his field of study
Wow this is really cool! Make more of these types of vidoes
I need more ideas!
DLR has a facility in Cologne to test objects in hot hypersonic jets. The gas is heated with an electric arc, and the facility basically has its own electricity substation to power the arc
the way brian just repels awkwardness from the air is absolute giga chad
Due to an increase of orders for same day deliveries made at 11:59 pm, companies finally invested in hypersonics
Neither snow nor rain nor heat nor gloom of night…
Hey, if this is what gets us to faster-than-light travel, so be it.
Now this is what I signed up for
This was so cool! I love videos that start with a goofy premise but evolve into a high quality bit of sci-comm Would love to see more field work like this too, reminds me of some of my favourite Veritasium videos
This is fantastic, I'm glad you took this idea on and made this video!
I like that you discussed the aerodynamics and wing mirrors on the new truck then bought a model of an old truck! Haha. Fascinating results though! You can see how a nosecone above the cab would help keep the nose down when passing mach 4 on the highway.
In regards of 9:18, I can finally contribute something to a video of yours: I work on a test rig for hydroelectric powerplants. And operate it. And it is the norm, that nothing goes as planned. Every project is planned to fit neatly together, but in reality, there are just so many uncertainties, that problems pop up everywhere. Its probably the best, when you start the shift with the mentality, that everything is going to fail und you are here, to get it running nevertheless. That's R&D.
Actually very well done, the explanation after was right on & why I had 100% retention! Great work! I have been watching for awhile now and have never been so locked into a video👍
Seeing you makes me appreciate your channel more. You are doing amazing work. Keep going!
I clicked thinking this was maybe a Veritasium or Hacksmith video lol
You should make more videos with them if you can. Maybe a hypersonics paper airplane? Or something that is already made to go fast but make it go faster to see that happens like a bullet?
>makes a vehicle that is a literal cube on wheels "guys look how aerodynamic it is, the wing mirrors are smooth!!"
I'm really surprised they let you film there in that much detail, given how important that equipment is for developing cutting edge weapons
3:30 that made me laugh way more than it should have 😂
Great video! I visited this facility over the summer and all of the staff there are so energetic and into their work!
Thank you for explaining what types of videos you have on nebula. I was not sure if I wanted to purchase it, but now that I know that you cover more of the math in depth there, I definitely will!
The mention of notjustbikes when the demonstrator mentioned the analogy of adding lanes to a highway was hilarious 😂
My motivator . You help me appreciate PHYSICS more
Your best video yet!! Funny but covered a very difficult topic. You managed to keep it interesting while not dumbing-down the content. WELL DONE!!
This has a hanging out with the boys vibe and I love it
This is amazingly beautiful, love the animations
This may be your "stupidest" video but i got ABSOLUTLY AMAZED by that machine, that made me have some ideas, didnt know about the pressure differencial didnt increase air speed
Ah, welcome to Austin! Hope you’re don’t mind the heat too much lmao
I fucking hate it. I usually try to spend summer back home in Ireland. Couldn't this year with the filming schedule.
@@RealEngineering Woah Language!!
@@RealEngineering fair haha My AC has been out for a week and lemme tell you i don’t under-appreciate that miracle invention anymore
The guy in charge of the facility did a fantastic job of explaining the work with a fantastic balance between technical jargon and understandable lingo. I really appreciate it!
That's one absolutely awesome way to demonstrate a high speed wind tunnel! The animation where it almost, for just a moment maintains stable flight... Was also priceless!
I love the super scientific storage devices on top of the wind tunnel cleverly disguised as red Solo cups!
Being in front of a camera is a whole other skill set people have to develop, but it seems you're aware of this so I'm not concerned. In any case, this is a great first test.
Fantastic making the complex easy to understand.
Such a fun episode. Great work my dude!
I had a chuckle at the fact that you're in Austin and had to drive to San Antonio to go to UT.
I love that you mentioned notjustbikes when Chris Combs mentioned that more lanes = faster traffic!
The Best video ever made from Real Engineering very much fun Testing U haul in Hypersonic wind tunnel
Such a fun video. I love your usual format, but a little silliness is delightful.
As a controls/instrumentation engineer I'm slightly concerned there was an Arduino on a critial part of that system 😆
Arduino's are quite robust micro controllers to be used for science instrumentation.
It works, it's cheap, and it is damn easy to work with.
They said it's just a part of the camera triggering mechanism and they could run the test without it, so it wasn't actually critical. Besides, a properly-used Arduino is arguably no less reliable than some other microcontroller on a custom PCB
This is kinda crazy that you can get something like that to go hypersonic
I appreciate the hyper realistic simulation of the truck going hypersonic
It's awesome that you are so organized with your upload schedule. I know if I see a video on here theres a new one over on Nebula for me to watch.
When Engineers have nothing to do 😂😂
4:24 huh... I guess at hypersonic conditions you can't assume a sphere.
Aerodynamics is the only part of physics where assuming a sphere doesn't work.
i dont know whats funnier, you rocking up there to test a uhaul truck in their hypersonic chamber, or the fact that the dude who works there pulles out the mount and it has a cow attached to it 😂 im really glad we got to see a hypersonic cow!
Dr. Combs is awesome! Glad to see such a fun collaboration.
This is definitely the right direction for the channel long term. Of course, the voice-over videos are ones I very much enjoy, but I'm already seeing KZhead absolutely crowded with AI-generated, faceless content. And sadly, I think the situation is only going to get worse with time, especially as companies continue to march onward recklessly in the AI arms race.
Now I want to know how aerodynamic a cow is. Can we get a video on that?
Lol, apparently brilliant minds think alike..😏
m.kzhead.info/sun/id2xfb5qrYVpl4E/bejne.html
Amazing. Love your work
Wow. This was incredible. An amazingly fun video
It's weird hearing people talk about I35 driving lanes being 6 lanes wide. I'm at mile marker 1.0 & it's only a 4 lane divided highway. Also, to the guy in the lab with the MN Vikings hat: Skol!
To be honest the title and thumbnail are so insane that it put me off clicking for a day or so. cause I was like no way that is actually what happened. the thumbnail of it flying is what did it not so much the title.
"Still has the cow on it from a couple weeks ago" dude i want to hang out with these guys on slow days 😂
I watched this on nebula and had to click on it on yt too just to tell tou how awesome this episode is. Seeing you as a real person and not just a great narrator is a very great change. You're doing great. Keep the Amazon content coming
Amazing how even in such high tech scientific facilities, they still use an Arduino
and naturally, they still fail at the rate of arduinos. but that's okay because grad student time is cheap, as my advisor would say
It's so specific and engineering dictates to choose the hardware specs based on requirements. For reading a couple of values and sending them out a couple hundred times a second, an arduino is a sufficient and simple solution that reduces development time.
I love hearing your personality in the footage. Never cut out the laughs!
I love this video, really shows what engineers are like in person
This video was so much fun! I love it, the simulation animation is hilarious haha
4:20 I like how Stephanie (from Real Science) helped Brian in making this video
I have that same Navy dress shirt with white polka dots and I always roll the sleeves up. Glad to see all engineers wear the same 3 outfits
"Did we get it stable?!" I love the joy in his voice
6:20 OMG loved this!
nice seeing you on camera, you are definitely made for it
