Imagine this, but instead of a cylinder you had a sphere suspended in corn syrup, with the ability to rotate it on multiple axies. The effect would be absolutely mind boggling. Thanks for this great video!
At first I was like "of course its gonna work, it's not that amazing" But then I was like "wait a minute, this is insane if it works" And then I was just in disbelief. Great video!
it wouldve altered my capacity to want this information at that age. instead i got a literal pocket protector, unibrow drab teacher. killed it all dead at that age.
I fast forwarded just has he did it, so I accidentally fast fast forwarded it, so then I fast backwarded it, to slow it down. And I ended up at the beginning again. Everything had been reversed any way. Is this a glitch in the matrix? And did it work either way?
@@sirmorningwood2707 The striations actually prove nothing about entropy being maintained or reversed. As he pointed out that is just a side effect of the way they mixed it. If done properly, the laminar flow would return the liquid back to its original position without striation. In any case the original premise is flawed, because you are not actually undoing entropy by returning the liquid to its original state, any more than melting an ice cube and then freezing it again means that you have reversed entropy. The energy (and subsequent heat) that went into the system to "mix" the liquid was also required to then "unmix" the liquid. As such, the continued entropy of the universe was maintained. That being said, I have long held that the Entropy is a severely flawed theory because if the ball must always roll downhill, then how did the ball get to the top of the hill in the first place? Even if we follow a multiverse theory where our universe splintered off of another universe through an extreme amount of energy focused on a very tiny point (Michio Kaku posited this at least), and assuming that the laws of physics are constant across universes, then you'd still have the problem of explaining how our parent universe got it's initial energy and so on.
the title is a bit misleading - nothing is unmixing, because nothing was mixed - the hint is in the rest of the title "ultra LAMINAR flow" - which means he didn't cross the "streams" and the pockets of dye could be mechanically reformed by reversibly compressing the "stretched" pockets of dye - really only possible because over the timeframe of the experiment, there was so little diffusion of the dye pockets into their surroundings - thus the requirement for a really viscous/thick liquid. The law of entropy always increasing was still demonstrated because the "after" pockets were more distorted than the "before" pockets - because of an increase of entropy throughout the experiment.
@@nradicic Well I think that all comes down to what your definition of "mixing" is. Considering that the corn syrup is already homogenized and the only difference is the food coloring, one could say that it is already mixed even before he starts turning the handle.
If an electron and a positron collide, annihilation occurs. But if an electron and a proton meet, a neutron can form. Why the laws are asymmetric wrt the mass?

Wow. The experiment was great but what I found more touching was your explanation of how it compares to life . I myself have been through a lot and struggle to see the light at the end of the tunnel at the moment but you have just given me a light. A reason to keep on trying and keep on believing that with effort and with the write steps we can make things good again instead if staying in a mess and thinking there is not hope. I know it may not make sense what im trying to explain but in short I just want to say thank you. You have given me hope. Things (life paths) can be fixed and can be reversed.

I believe you begin to lose some of that reversibility due to a rising Reynold's number. Reversibility amongst fluids is really only observable in slow moving flow
I don't know if counting is even necessary. I guess you might need to keep the rotations to a limited number, and as long as you do that then just keep counter rotating the cylinder until you get the initial condition you started out with.

Would have been good to see: 1- a before and after photo, side by side 2- making a simple draw, like a smiley face, to effectively see it being reconstructed.
Destin, I go back through your old videos on occasion when I'm reminded of some concept or visual that I remember is cool and I'm always a little bit sad you (and UA-cam) weren't around when I was a kid to get me as fascinated by physics as I am as an adult. But I'm also so thrilled that you're here for my little girl and I'm so excited to teach her all about how the world works and feed her curiousity while it's still hungry.
"the velocity at the free surface, is the velocity of the free surface" My favorite aerodynamics professor made us repeat this over and over again... Still true and still a good fluid dynamics lesson.
Hey Destin, I came across something quite interesting recently. I was making hot chocolate and to cool it off I placed an ice cube in the cup. What happened next surprised me, the liquid started to swirl as if I had just stirred it. I found this fascinating enough to where I did it again; on my third time around nothing happened. Assuming it was the heat of the water acting on the melting ice I made another cup and sure enough, it started swirling again. The ice I was using was cylindrical in shape and around 2.5cm. I did this again tonight and decided to measure the variables. At my altitude of 239M above sea level, the temperature of the water had to be no less than 79C, and the ice, if larger than 3.3cm wouldn't produce this effect. The cup was 11cm in diameter and 10cm tall. Now that all of that is on the table, here's my question. Do you know what causes this, or would you be able to help me figure this out? I understand that it isn't very interesting for most, but it is baffling me as to why it happens. Thanks!
I belive the ice cube cooling down the liquid causes it to sink and thus creating a swirl. I read about a phenomenon that caused a gigantic ice circle to spin for no apparent reason. It was later revealed that this was caused by the same reason that is affecting your ice cube. Not sure about the variables though.
@@veritasiumaequitasius3530 no Brownian motion should work only in collidal solution and that too on a microscopic level not visible.(well but if it's diffusion then that could be explained by Brownian motion I guess)
I'm going with 'Significant discontinuity' on the surface of the cylindrical ice cube. Of course, the cube is melting on all sides, but at a particular point, there is what I imagine to be a linear indentation allowing the melting to be focused and directed in a specific direction, causing the spin.
Quickly becoming my favorite UA-camr. Amazing, fun content and when the presenter is as excited and so enthused it really makes for great informative videos. Keep it up, you rock!!!!
I've watched this video before, as well as many of your other videos, and I never get tired of seeing how excited you get during your experiments. You would be the perfect science teacher because you are so great at explaining things and you make science fun. I always love watching your videos.
@@ysosirius8470 He only did 6 rotations. He only did 6 in reverse too. He either miscounted both times, or edited one rotation in each direction completely out of the video for some reason.

Ohmygosh this blew my mind too! It's so amazing how everything you used (save for the device) can can be bought in a store and the beauty is all because of simple mechanics and laminar flow. It's one thing to know the theory, but to see it in action is amazing~
Destin, I took your advice and read The Sun Does Shine and that was one of the most moving books I've ever read. Cried like a baby! Thank you for sharing!
Numberphile just did a video on Reynold’s Number that references this video and time travel. Portions of that video were way over my head, but as soon as the professor starts talking about processes that can be reversed, I thought of this video. Then Brady actually mentioned this video and put bits of it in his video. Pretty cool. 😎
God I love watching his videos, just the sheer excitement and the passion for science he has makes it so much more fun to learn science and actually get smarter everyday. I’ve always loved the science behind things and always want to know how things work but all throughout school teachers just aren’t as excited about science like this. At least not here in Arkansas where I’m from.

Everything is connected to philosophy :)
Would have been good to see:
1- a before and after photo, side by side
2- making a simple draw, like a smiley face, to effectively see it being reconstructed.
I really liked that metaphor, it was something i needed to hear. Thanks Destin!
Destin, I go back through your old videos on occasion when I'm reminded of some concept or visual that I remember is cool and I'm always a little bit sad you (and UA-cam) weren't around when I was a kid to get me as fascinated by physics as I am as an adult. But I'm also so thrilled that you're here for my little girl and I'm so excited to teach her all about how the world works and feed her curiousity while it's still hungry.
"the velocity at the free surface, is the velocity of the free surface" My favorite aerodynamics professor made us repeat this over and over again... Still true and still a good fluid dynamics lesson.
"You're going to have to watch this entire video to fully appreciate it"
"#26 on trending"
Hmm...
People go to trending?
I don't think they believed you because this experiment is being described incorrectly. The colors were never mixed in the first place
Why are you talking about ryzen 3000 and Navi launch on this video
@@Tridd666 nice profile pic
Hey Destin, I came across something quite interesting recently. I was making hot chocolate and to cool it off I placed an ice cube in the cup. What happened next surprised me, the liquid started to swirl as if I had just stirred it. I found this fascinating enough to where I did it again; on my third time around nothing happened. Assuming it was the heat of the water acting on the melting ice I made another cup and sure enough, it started swirling again. The ice I was using was cylindrical in shape and around 2.5cm. I did this again tonight and decided to measure the variables. At my altitude of 239M above sea level, the temperature of the water had to be no less than 79C, and the ice, if larger than 3.3cm wouldn't produce this effect. The cup was 11cm in diameter and 10cm tall.
Now that all of that is on the table, here's my question. Do you know what causes this, or would you be able to help me figure this out? I understand that it isn't very interesting for most, but it is baffling me as to why it happens.
Thanks!
I belive the ice cube cooling down the liquid causes it to sink and thus creating a swirl. I read about a phenomenon that caused a gigantic ice circle to spin for no apparent reason. It was later revealed that this was caused by the same reason that is affecting your ice cube. Not sure about the variables though.
Convection cycle?
Brownian motion?
@@veritasiumaequitasius3530 no Brownian motion should work only in collidal solution and that too on a microscopic level not visible.(well but if it's diffusion then that could be explained by Brownian motion I guess)
I'm going with 'Significant discontinuity' on the surface of the cylindrical ice cube.
Of course, the cube is melting on all sides, but at a particular point, there is what I imagine to be a linear indentation allowing the melting to be focused and directed in a specific direction, causing the spin.
I thought I had seen this before, and I was right, but I watched it all the way through again. Great video.
Quickly becoming my favorite UA-camr. Amazing, fun content and when the presenter is as excited and so enthused it really makes for great informative videos. Keep it up, you rock!!!!
says not to fast forward, to experience this in real time, then 3X speed activated at 4:55
hah
I'm glad somebody else noticed this.
I laughed
Nobody:
Destin: *M O R E L A M I N A R F L O W*
I've watched this video before, as well as many of your other videos, and I never get tired of seeing how excited you get during your experiments. You would be the perfect science teacher because you are so great at explaining things and you make science fun. I always love watching your videos.
His reaction was just as amazing as the video. His passion is infectious.
Absolutely amazing!
This blew my mind. I have no more brains left. Gone. All of it.
I know that feeling.
teache:r count to seven(don't ask why)
him: 1,2,3,4 uhhhhhh ,6,7
hyperbeam 94 he did the rotation but didn’t count it
@@ysosirius8470 He only did 6 rotations. He only did 6 in reverse too. He either miscounted both times, or edited one rotation in each direction completely out of the video for some reason.
wdym “him” he’s my man Destin
@@philp4684 He said he lost count in reverse as well. He probably just turned until it got back to where he started.
Benjamin Wang
Him is a nonspecific noun of reference to a singular male. The context of the video designates who the “him” Wdym by such a Dumbass question?
Ohmygosh this blew my mind too! It's so amazing how everything you used (save for the device) can can be bought in a store and the beauty is all because of simple mechanics and laminar flow. It's one thing to know the theory, but to see it in action is amazing~
Wow Destin! I love your enthusiasm. As always, very inspiring. Glad to see you thriving. 💪🏽🤜🏽
"Like" doesn't adequately cover this. I love it and the metaphorical meaning. Thank you Dustin.
Ha! Destin lost count the same amount both ways. He did 6 turns not 7.
6 in 6 out is what I got as well.

Awesome video.
Subscribers: so , how many laminar flow video will u make?
Destin : YES!
?

08:09 That heart attack moment when you are in public with your headphones and forget to plug in the aux-cable before you hit play.
If I could put my heart in the judge's heart, he'd know I didn't do it. On a plane. Lmao that'd be an interesting situation
Chann Polk Haha indeed
Thank you so much for sharing and learning with all of us. You are my absolute favourite UA-cam channel ever since I discovered you. Happy new year!
“Don’t fast forward this video”
Me: Challenge accepted
Destin...Challenge FAIL! lol!
This was maybe one of the coolest videos I’ve ever seen. I fundamentally LOVED this!
You pretty nailed the couette prononciation
(Random French guy here ;) )
Btw couette means blanket in French
You're either trolling or learned some terrible French. Couette is one syllable, said like qwet, and related to hair, not blankets.
@@Nathan-dt2tu blankets too
Destin, I took your advice and read The Sun Does Shine and that was one of the most moving books I've ever read. Cried like a baby! Thank you for sharing!
Mind officially expanded to new depths. Thank you for that. My heart raced as well watching that life changing moment
hey it's me Destin from LAMINAR FLOW
I think you are talking about sperm but does sperm flows in leminar way, I think that's a turbulence flow.
Nothing more Destin than Laminar flow!
"What do you do when you do the thing you've always wanted to do? I don't know what to do.
Do we go the other way? - Let's do it!!"
Cool stuff!! Everything you do makes science fun! Keep it up!
0:30 Your pronunciation of Couette is excellent =)
Fun fact : in french, the word couette means a quilt
This is the closest thing we have to time travel
Staneagle 79 you’re an idiot
Numberphile just did a video on Reynold’s Number that references this video and time travel.
Portions of that video were way over my head, but as soon as the professor starts talking about processes that can be reversed, I thought of this video. Then Brady actually mentioned this video and put bits of it in his video.
Pretty cool. 😎
Can you post a link to the other video you mentioned? My 13yr old is really into time travel.

No that’s Keanu reeves age
God I love watching his videos, just the sheer excitement and the passion for science he has makes it so much more fun to learn science and actually get smarter everyday. I’ve always loved the science behind things and always want to know how things work but all throughout school teachers just aren’t as excited about science like this. At least not here in Arkansas where I’m from.

*Nice trick !*
The paint was separated in different layers. It was never mixed together, just blurred in separate layers.
yes. but the layers were clear so ... magic? Magic.
Such an old school style SmaterEveryDay video, I love it man.
Once again, you have blown my mind. Thank you, again.
He blew my mind and I blew my laminar flow. :P
Dustin “is you heart pounding?”
Me: “I hope so!”
Absolutely LOVE your channel! Thanks for making me smarter!
Counting up to seven never was this hard! 😂
.
P.S. Love your videos 👍
But didn’t they only do six
3:00 I see the spirals..
Cue the music, Sound Remedy & Illenium - Spirals
Great life message using the laminar flow analogy. I have become your fan forever.
Your pronounciation of Couette is pretty good actually.
Coming from a french speaking person.
Pretty easy considering everyone knows how to pronounce baguette
@@orb5951 Yes, but can you say camembert ? Because a baguette without camembert is like life without meaning.

I wonder if there is an amnesia clause.

BarackBananabama, good thought... but if it is done correctly, you'll forget what you heard and ultimately never know it you heard it...maybe you already did!!
thank you man i needed what you said at the end of this video about things feeling like they are unfixable but if you don't rush to fix it, it will probably turn out fine, i needed that because i have had a nightmarishly bad past 7 days and that really helped me relax about it. Thank you so much
