[intro theme] Greetings, children, Captain Disillusion here. Let’s get right into it with a recent video that’s been all over my feed– [Going Up the Country song]
Oh, okay. Not that, sorry, heh. We’ve had a few, uh, out of context reposts of the last, uh– How about–nope. Nope. Uh, maybe something, uh, on Instagram? [Going Up the Country music]
No? No– Y’know what? Let’s just check the old inbox. [Going Up the Country repeats] Ow! Okay, there’s gotta be something I can talk about. C’mon. Ah! Perfect: a baby! The little baby from Tik Tok that draws really well. How bizarre? Let’s examine this. Okay, so the hand looks kinda weird, swiviling around in the sleeve, but maybe this child is not as young as she appears, y’know certain conditions can– then again there’s the part where she looks away from the paper while still drawing. And that’s a little bit of a– What’s this? Oh. Looks like you guys have already… brought up all these points, and educated each other about it everything there is to observe in this video. I guess I’m not bringing anything new to the table. Let’s pick something else. Uh. There’s– There’s this one: it shows a stream of water frozen in place. …until a hand touches it, revealing it’s actually flowing. According to the title, this is a phenomenon called ‘Laminar Flow.’ But–it looked so magical. I think that– Oh. Looks like there’s lots of input from you guys here as well. Some sophisticated explanations… (Sighs) I suppose I have no choice I’m going to have to dive in and analyze your analysis. To test the wisdom of crowds. There are other examples of this kind of video out there. And under each, usually at least one expert opinion setting the record straight, that this is NOT laminar flow, that that’s not how it works, that it’s fake. Indeed, if you look up scientific demonstrations of laminar flow, you find that it’s pretty involved. Viscus sugar syrup mixtures, dyes, devices pushing liquid through horizontal tubes at just the right pressure relative to the tube’s diameter, the Reynolds number. What am I, Smarter Every Day? All I know is, tutorials on how to construct an actual laminar flow nozzle don’t make it look easy. This ‘King of Random’ build seems like an all-day project, YouTuber ‘djdegraaf’ went through several iterations of their version before they got the device to work right, a nd Don Jupp appears to have been perfecting his nozzle for the better part of a year. In the end, they all achieve a stream that’s pretty smooth and stable, but the doubters in the comments have a point: laminar flow nozzles produce a perfect tube of water, like a liquid laser beam, but these viral examples are organic and complex. It doesn’t look like the same phenomenon. So how do the ‘experts’ say this kind gets faked? I’d really like to educate myself. [CD reading comment] The relationship of between the frame rate of the camera and the frequency that the water is moving at–
[Normal CD] What?? Oh, I think I know what they’re trying and failing to describe: I’ve seen this trick where a water nozzle is vibrated by an audio speaker and magically attracts huge views! Legendary tinkerer ‘brusspup’ did a couple of these experiments, and then Vlogger ‘Wolfie’ saw that and did it, too. But louder and ‘funnier.’ [Wolfie] Todays video might get a little bit drippy. So now that I’m shooting on 24 frames per second–If you don’t do that it’s not going to work. (*buzz*) I’m going to make this water spout moving in 3… 2… 1… Here. (*feedback sound*) Back to the drawing boards. [Captain] Now wait a second, they talk about frame rate, but these guys mention shutter… and these ones use the term, ‘sync.’ I’m getting confused again! If we’re gonna explain to the masses how something works, we should understand the details a little better, cuz, you know, imprecision can lead to all sorts of unexpected effects. Woaaaaahhh Aaaaaaahhhhh! (*thud*) Ugh. Uh. So, let’s brush up on the protocol: water, runs through a tube, that touches the membrane of a speaker, which plays a tone of a certain frequency, which vibrates the end of the tube, which fans the water out. But the whole thing is being filmed by a camera, which records pictures, or ‘frames,’ at a constant rate. When the frequency of the audio tone is the same as the camera’s frame rate, or if your speaker’s not banging enough, a multiple of the frame rate, the flow looks like a sine wave. [Wolfie] I’m going to make it freeze in 3.. 2.. 1.. Boom! It’s Frozen Fully frozen! You already know… [Captain] Well, no, Wolfie, the water doesn’t look frozen, does it? It’s just the wave in which it seems to flow isn’t moving. If the tone’s frequency is slightly higher than the frame rate, the wave appears to travel forward. If it’s slightly lower, the wave seems to move backward. Trippy. But I don’t think it’s right to call them ‘synchronized’ because the speaker and the camera aren’t being coordinated to stay in sync. No matter at what phase of the tube’s 48hz bounce you power up the camera, it’s 24 frames per second record rate will make the water wave appear stationary. The two aren’t synchronized, they just happen to be synchronous, thanks to the precision of digital devices. And although it helps make the effect clearer, shutter speed has nothing to do with this. That’s just the time sampling within each frame. See, 24 frames per second doesn’t mean a frame captures 1/24th of a second in time, the camera’s shutter is open for only a fraction of the frame’s time. And shutter speed is actually measured as either a fraction of a second of real time, in photography where there are no frame rates, and in broadcasting where there’s one standard frame rate, or as a relative shutter ‘angle’ in the motion picture industry, where frame rates often vary. But don’t ever worry about that. Just know that’s why people’s videos of the experiment have different degrees of motion blur from shot-to-shot. Their shutter is usually set to ‘automatic,’ and changes with lighting. Slower shutter speeds makes the wave fuzzier, but more contigious. Faster shutter speed makes it sharper, but can break the wave into descrete dropplets. Or, I guess, reveal the droplets as they really are. Fascinating, isn’t it? And I guess the most important thing to note about this is that it has absolutely nothing whatsoever to do with laminar flow! I mean–am I crazy? Are we looking at the same videos? Nothing about this looks smooth, or still, or laminar! So what are you on about, Rahuls, Oscars, and Perkins’ of the world?? You know, catching a glimpse of one interesting phenomenon and then casually drawing a tenuous mental link to another one you’ve heard of is not knowledge, or expertise, or a license to explain it to random people on the internet with the confidant arrogance of a young *me*. So the question remains: what exactly *is* laminar flow? The answer is this. AND this. Because, laminar flow is just a blanket term for fluid flowing in parallel layers. As long as it’s doing that, it could be any shape, moving at any speed. And for all you haters out there who don’t believe this is possible, why don’t you just try it yourself?! (*water flowing*) [zen music] No tricks, no effects. This beautiful thing is really happening. Look, if you want the perfectly shaped liquid tube, then the complicated laminar flow nozzle DIY project is for you. But, if all you’re after is the laminar part, and don’t care about the shape, then it’s easy. First, fill a standard party balloon with water. Then, to show yourself the power of Flex Tape™, cordon off a small area for the nozzle, so the whole balloon doesn’t explode. And finally, stab a hole in it. Seems the only ingredients needed for basic laminar flow are: 1) That the liquid isn’t propelled before reaching the nozzle, which could introduce turbulence, and 2) that the rim of the nozzle is very smooth. As with many things, latex takes care of both. And that’s why this video is real. And the expertly commenters were wrong. They were so preoccupied with wether they *could* explain it, they didn’t stop to think if they, like, need to even, like, do it at all! Let’s face it, if I wanted to created a water-based hoax, why would I do something as simple as making it stand still? I’d probably shoot for something a little more elaborate. Wait a minute… I learned my lesson. Better take thorough anti-freebooting precautions. [Rad dubstep music] [CD Theme] But now I’m afraid it’s time for me to go, kids.

“What Am I, Smarter Every Day??” 😂😂😂
Wait, so is it real?
with such a big hole, why isnt your balloon showing any signs of being emptied? it should shrink.
I’m so glad jack shouted you out, this is so cool
He looks like a teacher from Malcolm in the middle
Rip king of random 2:20
New subscriber i like your videos
Till now you made me understand the things in your videos, but this time didn't get much. Got that it's not a fake but how is it so still. Wouldnt there be at least some light changes as the water flows. I'm trying to say that at home I do get some perfect flow's as I adjust the water in the shower, but I can still recognize that the water is moving. Why does it look like a picture? I'm not skeptical or anything. Just want to understand it. Thank you!
Hi king of random
Who is here from jacksfilms content award
Is the “paint” on your face a green screen or something?
Man, Captain really knows how to shut some people up.
My piss is laminar flow.

Captain D . Check This out
Came because of Jacks films
Stayed because of the quality
zach king : im the best youtubers vfx
captain : hold my beer
5:27 RIP kurzgesagt bird
Which was the video at The start?
This content is fAkE. ToO mAny cAmEra trIcKs
Me : opens video
captain disillusion : greeting children
My mom in my room :
I hope they don’t fix this bug in Earth Version 2020
RIP The King of Random

Is this fake???
Getting wine from my bag-in-box earlier today caused it to have laminar flow. Kinda trippy, tbh.
Damn man you are awesome!
Lol kurzgezagt duck customized for you xd
If laminar flow is a "term for fluid flowing in parallels layers", why do you call laminar flow the one une the video? There is nothing parallel in it. Am i wrong ?
jesus fucking christ the production value of this video 👏👏
Haha i just realized the sound FX for the comments popping up are from DUKE NUKEM 3D, fckn awesome 😀
it has happend to me but i was not recording :[
Johnsvideos brought me here
Like if u agree
It's just melted plastic
How does he only have 1.6 million subs
8:25 omg he listens to hello internet
Rip the king of random 🙁
5:27 poor ducky
2:40 Rip The King Of Random
Next time debunk those flat earth community! 😆
In my sink it’s clear like laminar flow
Still confused why it looks still
Every other video I see of laminar flow you can tell it’s moving
I love the special effects you got to teach me but in private
It never works for me
dude, this guy has not changed at all over the years. Put it in 144p for OG Captain Disillusion watching mode.
He acts more like he is in a kids TV show than he does a YouTube channel.
oh i was hoping he would show how its done lmao damn
most underrated channel.
If this guy would make a super hero movie the movie will have beautiful effects
7:53 HAH sex joke.
So hey you know the video with the buddha statue what song was that plz help
I've been to Kislovodsk. It's famous for its mineral water Narzan.
Actually, the shutter and flow rate are not synchronous, but isochronous, since they use different timing sources that happen to have the same frequency.
RIP Grant Thompson, King Of Random
The real laminar flow was with us all along
I suspect this video to be fake
You are just amazing at editing and vfx cap. I am new to this but i loved this debunk. Please keep making more.
Possibility that put 2 speaker at 2 side then make some song and make a squashing the water shape
Fake
Oh, come on. Kabbalah isn’t that hard to spell.
Try Hanukkah.
What you are saying in final is fake or not.
Rip grant
Hey Captain i'm from Pyatigorsk and i know how to spell Kabbalah
My little tap can do that i tought it was ice but i touched it and it got all over my face
You're the owner of the Chanel kurgezagt aren't you?
how does this dude have one million subscribers????
Smartereveryday would like to know your location
Grant
best view he made by far
I hope that Captain D will be in YouTube Rewind 2019.
Love you CD
Merci pour la traduction
I think this video might be fake 🤔
2:23 RIP we miss you grant
what was the video at the start?
You look fat
Best YouTube channel since the old days
Cool
RIP King of Random
5:27 Oops, there goes the Kurzgesagt bird!
Looks like he debunked us guys
Abhishek Gupta is wrong.
Hello compact disc
I have seen this in real life it's not fake
Side note, I saw this at a water park
The part at the end is so fake it just looks to low quality to be a real stream
This reminds me of television. Yuck! No thanks jacksfilms.
Rip king of random
8:37 that is so fake
Anyone else keep seeing this in their recommendations and think he looks like he has wolverines claws?
Forgive me, but I am still…confused. Somehow, before watching this video, I was totally convinced that the visually stationary stream of flowing water, no matter how janky looking, was indeed laminar flow, and that whole vibrating/framerate stuff I had never even heard of, but now after, I am suddenly confused and am questioning it all anyway.

best youtuber ever. even slightly better than the instagram that posts random pictures of a creepy doll.
Kurgast’s duck got destroyed
I'm going up the country
Four pee streams?
8:27 No that is not real! That is just a camera trick and blah blah blah shutter speed blah blah blah!
I made. Laminar flow by accident
I see the real illusion in this video. It is just a clever way to advertise flex tape. Billy Mays would be proud.
In an attempt to replicate the Captain's experiment I accidentally found a much easier way to do it. Use a defective balloon! https://www.youtube.com/watch?v=I8Sno627PrE
Nothing worse than all the idiots who think they know and try to tell people in the comments.
Didn't expect you to put Kislovodsk into a video, or even for you to know about its existence
Its black macig
