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"
@@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.
@@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.
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.
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, UA-cam is filled with videos where content creators google something then make a video with a voice over on it with some pics and footage.
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.
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.
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.

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).
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 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
Brian - I literally (and I don’t use that word lightly) saw this graphic on the back of a U-Haul last week, and was wondering how I could call b******t on it (or be proven wrong myself). Bravo. Bra Vo.
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
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.
The U-Haul knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the U-Haul is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the U-Haul must also know where it was. The U-Haul guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
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
10:00 - Uhhh... why limit the camera trigger to the pressure gauge? Just run the triggering wire across the diaphragm (or use a laser aimed at the diaphragm). That way when it ruptures the camera is triggered.
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?
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
10:30 I like how this shows the reality of the scientific process. It wouldn't seem like triggering a camera would be a big issue, after all you have a gigantic hypersonic wind tunnel, and there are workarounds, but sometimes that's what the problem is!
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!
Man. If you were making videos when I was a teenager, I would've had some idea what college IS before going. This kind of stuff is gonna help a lot of kids find their interests and good opportunities in education.
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.
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!
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!

" - JFK
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 UA-cam 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.
I just spent 2 years as an undergraduate researcher at the University of Arizona working in the Mach 5 wind tunnel. This video gives me so many ideas of objects to put in the tunnels.
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

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
Shout out to your animator Eli for superb work!
I enjoyed this "less polished" style. It felt inclusive and personable.
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
This has a hanging out with the boys vibe and I love it
I'm absolutely impressed that the little plastic toy didn't immediately disintegrate in the mach 7 air.
Fantastic video! Thank you for visiting our lab.
"I don't know what we learned, but I'm excited"
Perfect summary of this video lol
Brian - I literally (and I don’t use that word lightly) saw this graphic on the back of a U-Haul last week, and was wondering how I could call b******t on it (or be proven wrong myself). Bravo. Bra Vo.
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 LOVE that you're willing to do something stupid-silly, but also EXTREMELY interesting!
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.
The U-Haul knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the U-Haul is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the U-Haul must also know where it was.
The U-Haul guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
Make this comment blow up
I had a chuckle at the fact that you're in Austin and had to drive to San Antonio to go to UT.
4:20 I like how Stephanie (from Real Science) helped Brian in making this video
Supersonic U-Haul trucks, supersonic cows, metallic farts and a big Problem Solver 9000 (aka sledgehammer). This episode had it all! 😂😂😁😁🤘🤘
6:20 OMG loved this!
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
"Still has the cow on it from a couple weeks ago" dude i want to hang out with these guys on slow days 😂
Really great video. Love you on camera
Wow this is really cool! Make more of these types of vidoes
I need more ideas!
The mention of notjustbikes when the demonstrator mentioned the analogy of adding lanes to a highway was hilarious 😂
"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.
10:00 - Uhhh... why limit the camera trigger to the pressure gauge? Just run the triggering wire across the diaphragm (or use a laser aimed at the diaphragm). That way when it ruptures the camera is triggered.
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?
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 🙃
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
After 7 years, we finally got something that is the closest thing to a sh*tpost.
What an improvement.
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
This entire video was excellent, but that NotJustBikes reference was just a treat😂
3:30 that made me laugh way more than it should have 😂
10:30 I like how this shows the reality of the scientific process. It wouldn't seem like triggering a camera would be a big issue, after all you have a gigantic hypersonic wind tunnel, and there are workarounds, but sometimes that's what the problem is!
Great video! I visited this facility over the summer and all of the staff there are so energetic and into their work!
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!
I love that you mentioned notjustbikes when Chris Combs mentioned that more lanes = faster traffic!
Man. If you were making videos when I was a teenager, I would've had some idea what college IS before going. This kind of stuff is gonna help a lot of kids find their interests and good opportunities in education.
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.
That cow must have been MOOOOOOVVIINNGGGG
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.
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!
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!!
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!
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
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
Now this is what I signed up for
I clicked thinking this was maybe a Veritasium or Hacksmith video lol
the way brian just repels awkwardness from the air is absolute giga chad
I love the super scientific storage devices on top of the wind tunnel cleverly disguised as red Solo cups!
"We choose to go to the Mach 7 lab. We choose to go to the Mach 7 lab in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.

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 UA-cam 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.
I just spent 2 years as an undergraduate researcher at the University of Arizona working in the Mach 5 wind tunnel. This video gives me so many ideas of objects to put in the tunnels.
This is kinda crazy that you can get something like that to go hypersonic
Cool video. Super surprised that you didn't just break.
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
nice seeing you on camera, you are definitely made for it
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.
YAY!!! An Arizona plated U-Haul!!!
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 had an amazing experience watching this. Laughing and thinking around while on my own. Definetly fantastic one
Now I want to know how aerodynamic a cow is. Can we get a video on that?
Lol, apparently brilliant minds think alike..😏

Expecting a video on the "Insane Engineering of the U-Haul Truck" soon now that you've done this 😂
When Engineers have nothing to do 😂😂
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
I'm really surprised they let you film there in that much detail, given how important that equipment is for developing cutting edge weapons
Those ThorLabs Optical Breadboard benches are hilarious overkill for their setup lol. Clearly they built with what was on hand in that lab.
I like that PHD shirt, i saw it used also with Engineer.
Here's mine;

A skilled trades person that solves problelms you created using methods you dont understand, and ultimately recieves no praise for that big promotion you recieve on creating that shiny new prototype concept thingy that will never actually make it to production in the form you envisioned because its too complex and too expensive, because i said so.

Lol
Hahaha... loved the "stretch goal" comment. This was exactly what I needed on a programming Friday. What exceptional equipment and folks operating it. Thank you!
Omg this is the aerodynamics of a cow guy. What a legend
Extra points for use of Real Genius footage as "B roll"!
What's the point of learning all that we learn if we don't have some fun with it? This is probably one of my favorite videos on here so far.
I’m glad you kept the struggles and problems in this video. It’s how science really happens.
