Think about the spin of each ring. See the mushroom cloud effect at the start? The centers of the ring are moving outward faster than the outside and creating a backspin. When they collide, even as the low pressure pulls material together, both rings are still spinning opposite each other and because of the magnus effect(if I'm thinking of the correct effect), they create a forward, or outward away from the main ring, pull. I can't articulate it very well because I'm just not smart enough, but think of a basketball's backspin, and how it creates a forward pull that lengthens a shot.
SmarterEveryDay Bro, did you just say “jif” !?!? Graphic Interchange Format... “gif”. You are a true hero to my girls and I and I have been subscribed for years, but that is unacceptable. 😂 ...and then not using Micah 7:8 for your Bible verse? Perfect video for that verse! God bless you brother. Keep up the great content.
Maybe there is a direct collision between an area in the low pressure zone and in the ink or the space between that causes the smaller rings to be at a 90 degree turn.
Could the reason for the 90 degree turn be due to the low pressure zone pulling material to itself then the momentum carried from the movement colliding with the material from the opposing side create a backspin and then create a new vortex
I dont think there is an actual 90° turn. Looks like many smaller collisions similar to the first. Like fractals. Id love to see this done in a place with 0 resistance if it were possible.
Hey Bobby dude this was sweet as heck wasn't it really wish I had seen it in real life but he's got 12 hours what an awesome use of the second Channel ;-) maybe how you do your behind the scenes stuff would be a cool second Channel
We used a computer controlled cylinder to pump fluid behind a rubber membrane to fire toroidal vortices out of the vortex cannons. We fixed one of the vortex cannon in a stationary position, and used a multi-axis microscope stage to align a second cannon to it… which sounds incredibly easy, until you realize that DYE density was an experiment all on its own. If the density of the dye mix was lighter than water, the vortex would go up. If the dye was more dense than water the vortex would fall. We had to overcome SO MANY VARIABLES and we basically spent about 4 hours figuring each variable. Water/dye temperature differential Water turbulence Water turbidity (cloudiness or haziness of a fluid) How to reset the aquarium Cannon Spacing Cannon Nozzle Cannon Shape Dye homogeneity in the vortex itself The piston displacement volume The piston stroke speed Rubber diaphragm tension, would make one side fire faster than the other. Water or air to drive diaphram? Firing speed (too slow and they drift, too fast and turbulence tears apart secondaries) We did a complete redesign of the cannon 3 different times. The Dye loading method was changed several times At times We tried to maintain negative pressure on the cannon chamber… we also tried to put shutters on the front of the muzzle. Ultimately I decided it was ok to live with dye dripping out of the front. We had to premix the dyes and eventually we got there. It got to the point where we didn’t even really know what success looked like and always thought we were there.
Wow, I thought the main issue was convection currents caused by the lights acting as heaters... or something. Boy, am I glad I won't have to work with fluid dynamics any time soon!
@@Shadow-us4oq In 30 years cameras will film in UV and IR and visible light, at ridiculous speed, with everything in focus, all the time, at a resolution which allows heavy zooming.
@@Chris.Davies If the current camera and media demands remain the same, that may be true for certain applications. But I think in 30 years, we'll be regularly recording immersive VR experiences instead of just 2D viewing. I see in 30 years (or around then) vlogs will be immersive and participatory, and movies will allow you to enter into the storyline and observe the characters side by side (or be one). We do have that to some extent with video games, but in 30 years I think VR will encompass video games, movies, online media, news, everything. I think anything media related will be participatory and interactive from a virtual reality standpoint. The camera's wouldn't just be 360 capture...they'd be able to map out 3D space and reproduce any environment for us to walk through, or fly, or shoot zombies, or have a virtual significant other that makes you happier than any real person you've ever met. "Hey, you talking to me?" "Nah, I'm just having a conversation in the Matrix." Of course that's assuming we don't blow ourselves up first.

My thoughts exactly. Thinking of 1.618 phi golden ratio, DNA/RNA helix, Ein-Sof, and Carbon 7. It does require much control or perfect observed conditions, of which chaos can interfere with greatly.
so..... what exactly do you mean by forwards? I can see many things in the human world that was supposed to pull us forward, they mostly ends up enslaving us in one way or another.
This was quite beautiful! Props to whomever first thought to do something like this and props to you for being persistent in recreating it. Your persistence was much appreciated.
Many years ago I did some research on thermoelastic effects with concentric discs. One unexpected effect we found was that the many round hot spots that formed always were a prime number. Varying condition we got from 3 to 23 evenly spaced spots. I would like to know what number of ring spots you generated, and what influenced the number of these rings.
Chris Heichel In my research, it was thermoelastic instabiliy. Friction causes temperature rise, which causes thermal expansion, which localizes heating to a narrow band. The higher the rotational speed, the greater the instability and the quicker the hot spots form. We even found that a plain paper ring could form hot spots on steel (blue oxide color) in about 0.7 seconds without even discoloring the paper!
Since the pressure differential inside and outside the ring would be consiastent around the whole ring, the ring being symmetrical, then it seems feesible that the collapse would break into the lowest possible whole number larger than one, at intervals informed by the dimensions and momentum of the fluid. The rings in the video I mean.
“I started this process simply wanting to re-create something that captured my imagination, but obviously it morphed into something much larger than that. It wasn't about Fluid Dynamics, or Motion Control. It was about Patience and Persistence. The value of surrounding yourself with people who get this cannot be overstated. David wouldn't[never] quit which taught me to power-through, even when it might not make sense on paper. Everytime we failed, we learned something. So ask yourself this: What are You too intimidated to try?” “All you gotta do, is fill the tank back up, and give it another shot” @5:15 That was very inspiring!

Years trying to earn a degree. You're not the only person who has spent years pursuing a goal. Let your video stand on its own. We can see. We can hear. If your hard work and patience inspires us, it will -- without the sermon.

Jehuty989 people I went to school with, even now get the odd remark about it, to me it's fascinating as it can do so much, I mean we can have a person pull 11G and go faster than twice the speed of sound! How amazing is that??? There's a video on my channel of me pulling 8G
Your persistence does you credit, good job and congratulations! I am similar, with regards to law and law enforcement, spending most of my spare time studying anything from psychology of criminals and officers, law and how it both is theorized and applied, and actually talking to officers, victims and criminals. While I'm not contributing to the field as much as I'd like, your story (and the words of Destin) gives me fuel and motivation to try and persevere. Thank you, and good luck in the future!
I wrote a paper on a machine that I made. I worked on it for 3 months, nothing came out of it, but I learned how to love what you work on, and that love makes it so that you can keep pushing on.
Photography was my fluid vortex ring and I pushed hard to learn everything I can in such a short amount of time. I love that you had the passion to pushing forward and to finally get that one moment you was looking for. Photographers sometimes wait months and even years for one picture and to me it’s amazing what that time comes because it’s a moment in time that took days weeks months and years in the making for that moment. Way to go I’m jumping up and down for you guys that’s awesome that you got it. I’ve always loved Science and anything and everting to do with it. Love what y’all do and keep it up.
I wanted to animate 3-D text. Blender was the software, and I tried about 3 years ago, and gave up. This time, I watched many RUclips videos, and finally got up the nerve to try. After many failed attempts late into the night...I did it ! Not an expert of course as you can see on my channel, but for a 65 years old with limited mobility issues, I finally am a little proud of myself...thanks Destin, your channel has always been an inspiration...from balloons in the van (with kids and Dad) to this...awesome
Man. I am basically researching this in superfluids (numerically). It's super cool (both literally and physically). Let me know if you want to make a video on something like that. I would love to work with you on it!
If you manage to accomplish this with LHII, you deserve a Nobel prize in both Chemistry and Physics. Might as well find a use for it in clean energy and medicine while you are at it and secure the Economics, Physiology and Peace Prize as well.
I remember watching this when it came out when I was a freshman in engineering school and not understanding much if any of the stuff yall were doing here. The message at the end stuck with me though, and now I’m a professional motion control engineer in my own right. I guess I learned something.
I wouldn't say its the most beautiful video on youtube thats just your opinion and others might agree. But what I would say is that its sad this video wont get the popularity it deserves. RUclips was made for videos like this but now it just seems like they've forgotten where they came from
The thing that i love the most in science is passion... when a scientist dedicates 3 year of his life to see "just ink in an aquarium" and get motivated to try over and over again with no garantee that this experiment will turn into something usefull or even gonna work this gives an amazing lesson. Passion is what really motivates people and it's real. Some times i forget about passion's existence this is why i felt so good watching this video, made me remember this is possible and if i'm not feeling that at the moment i just need to find my two vortex colision somewhere. Thank you to made me remember such a good feeling!!!
It took me 2 years of watching you everyday to finally get the message behind what you said. “All you gotta do, is fill the tank back up and give it another shot” That hit home with me. Thanks for always bringing my worst days completely the opposite with just a few simple words.
If Pythagoras were alive today, he'd be asking 2 very obvious questions: "Why Are There Always 18 Rings That Form After The Collision?"... "What Can We Learn From This Numerical Constant?" Please, see for yourself - pause the video during each take and count the rings that form. 18 lateral rings are formed after each successful dynamic collision, time and time again. 18 is the constant, but why is this? What can we glean from this phenomenon? I'd suggest that the number 9 may hold the secret to this mystery... I'd really love to hear Destin's take on this. Amazing video, as always!
There may be a scaling parameter involved that involves the ratio of the ring diameter and the strength of the vortex. I wonder if varying one of these two parameters may cause tha number to change.
+Eisen Feuer, was the 28-count an imperfect collision? The 18-count trend might only occur when then collision is flat. If that's the case, the angle with which the rings collide might be influencing the number of lateral rings.
Three years for one video... if this doesn’t drive home the point as to how hard, long, tedious, and ultimately rewarding it is to pursue and share knowledge, then I don’t know what will.
Because there was no explanation. Not even a pathetic attempt to explain the physics (or more precisely the physical theories) behind it. Thats not how you get smarter, thats showing fancy looking slow-mo videos for the clicks..and watching them for the lulz..
@@ParanoidMaster This guy doesnt understand the physics behind it & it IS just for the show. idk why that would put people off or why anyone would expect more from this guy.
As you got closer and closer, my heart started pounding faster and faster. But, I have to say, the vortex rings in the original paper looked a smidgen more perfect...
Fluid dynamics are fundamental in spacecraft propulsion. Understanding how this effect works, and being able to recreate it successfully 100% of the time might one day help us to colonize Mars or create a habitable artificial gravity aboard space stations.
I add that last bit about artificial gravity because the Coriolus effect is a big hinderance to creating smaller scale rotational g force - imagine if we were to apply this fluid dynamic effect into the equation for coriolus to off-center the fulcrum ten inches to the left effectively canceling out the big g on the y axis - how awesome would that be?
5:42 'So ask yourself this, what are _you_ intimidated to try? All you gotta do, is fill the tank back up and give it another shot.' '....this is what taught me _persistence...'_
QuasiTron Gaming I agree. I always find these ‘what’s stopping you’ lectures very played out and condescending. What’s stopping people is money, or time, or maybe their dream job just isn’t economically viable. Maybe someone’s dream is held back by their genetics. Granted, there are people who don’t do things because they don’t want to make the effort, but most of the time there are legitimate, tangible obstructions to dreams and ideas.
Paxus uhhh how bout not having a channel and fan base with a cash flow for just shooting ink in water. And actually having to work like another human being. Yea so motivational, try looking from another lense.
"Oh, we asked astronaut Don Pettit..." FFS, only Destin can so nonchalantly name-drop one of the great astronauts "...he just happened to be around..." :-D
Um.... No. He said that we "lost the technology" to go to the moon. Not that we haven't been through the Van Allen belts. And he was being largely hyperbolic about the "lost the technology" - not that we COULDN'T get back to the moon, just that we stopped making the stuff needed. And both "quotes" aren't actual quotes by Pettit or another NASA engineer, but science-doubters misquoting/misinterpreting them.
Anonymous Freak I've heard him say it, your a liar sir, do you work for fake nasa? You gotta be pretty thick to think that nasa stopped making the technology that sent them to the moon and made "history"
Why would NASA keep making now-obsolete technology? The F-1 engine (the engine of the Saturn V) hasn't been made since the mid '60s. The AGC (Apollo Guidance Computer), in addition to being ridiculously out of date, hasn't been made since the early '70s. Yes, we *COULD* build technology to go to the moon again - such as SLS or BFR, but it isn't available *NOW*. After Apollo 17, there was zero reason to keep making "moon technology."
Anonymous Freak ok it's not moon technology its space technology, and don't tell me they wouldn't keep updating their technology?? The gasoline engine was built over 100 yrs ago but they keep updating the technology don't they. Plane technology is kept updated all technology is updated, but not moon technology???
Aayush Dua I have just watched this on a 4K HDR LG C7 and was just thinking how great this footage is, and how Destin’s edits keep getting better! Great job Destin!
I'm just thinking about how that could be used for VFX. This would look awesome for a collision in space, or animated as 2 balls of plasma colliding. Collision physics is cool, man.
That is so awesome. I am always impressed on how Destin finds people that REALLY LOVE what they do to make incredible videos like this one, it's so cool :)
congratulations on the project and I hope you understand that it was not only a lesson on how to develop a project or perseverance. there is something much deeper in what you wanted to see during the project, those secondary vortexes after the collision are going to change the history of humanity shortly
This is seriously beautiful! And I am not talking only about the effect itself, but the whole scientific process that went into your head and drove your will to keep on going "because it had to be done". It may seem useless to some, but they would be fools, this is truly inspiring, thank you.
This is incredibly inspiring and actually gives me drive to pursue engineering. It’s so incredibly satisfying when you’re able to finally get the result you want. Thank you for this video because it actually makes me want to pursue these kind of things.
I didnt dislike it, but i understand why others do. We didnt learn anything new from this video that we didnt know from the potato camera video. We have the same questions. He did not unveil the mystery. he just recreated the same thhing
Neutron star it was too much time invested in something that may or may not be solved and which purpose is just curiosity rather than something transcendent like finding a new method of renewable source of energy, a cure for something etc...
Major Tom this is literally studying fluid dynamic, 4 years is a joke if you want to compare it with some other experiment that took decades. Also some other scientist are working on that not Destin. Its not his expertise.
so this is what fluid dynamics looks like in slow motion, one of the best vids since if first learned about fractiles, I'm hanging on to this one.........
I, like you, am fascinated with fluid dynamics. You and others may be interested in a study by NASA and the FAA in the 1980s to study vortex turbulence caused by aircraft, and the effects on other aircraft. To me, the effects of wingtip vortices on other aircraft was a no-brainer. These effects were the focus of this study on aircraft safety, while little attention was paid to the generation and propagation of the smoke streams used to make the vortices visible. At the time, I was involved in Unlimited Air Racing, and could usually be found at an airport, looking up. One of the usual suspects in air racing had contracted to fly his Hawker Sea Fury for the study to generate the vortices to be studied. They did this with wingtip mounted smoke generators developed by the government in secret. These were no ordinary smoke bombs nor fireworks, but used a secret formula to create the longest lasting aerial smoke trails ever seen. It reminded me of solid fuel rocket smoke. The Feds insisted on mounting and un-mounting the pods themselves behind closed doors. As you would imagine, as the smoke streams left the wingtips the spinning vortices became immediately visible. The objective was to fly another aircraft through the vortex turbulence and to note effects on that aircraft. Well, as happens with boys and their toys, the pilot of the smoke plane decided to fly his Hawker through some basic aerobatic maneuvers. Those of us watching have seen some of the best pilots ever to fly do these maneuvers flawlessly, but this time was different. Because of the extra dense and long hang time smoke of these generators, the spinning vortices did something incredible. As the vortices moved closer to each other, they began to unwind. Then astonishingly, the two smoke streams joined into single giant smoke rings, their diameter being equal to the wingspan of the plane. The formation of both the vortices and development of the final rings is very much like the effects noted in your experiments. Keep up the great video work, and stay curious! peace-out Tc
What you describe is an incredibly dramatic occurence of a well-known vortices instability named Crow Instability. Your analogy is spot-on, here: this is exactly what is going on in this video, with the two elongated contra-rotating vortex rings acting like two wingtip vortices. You see the same phenomenon quite often ensue in contrails, in clear skies. But not as dramatically as the occurence you describe ! Anyway, from a Physicist to a plane enthusiast: great intuition !
Tim Gochnauer I haven't yet found any super-secret smoke generator footage (the event Tom described), but I found this... ruclips.net/video/SMhwf--0pcc/видео.html Cooool!
Hi Sunshine, I have been watching videos on vortex in water the one that caught my eye was when a girl took a 12" plate in at the shallow end of a swimming pool and with one swoop down created two vortex. These two vortex started swimming laps together they lasted so long. I couldn't believe it one little swoop well over 3min. I thought that was cool until I watched watched this two colliding vortex producing baby vortex, I'm still replaying this in my mind. May peace an prosperity be with you always.
Steve-o yeah I watched that episode of physics girl too.... But the case here is different from there. There is a toroidial semi vortex with two openings rotating in opposite directions....(it seems pretty obvious ., As clock wise rotation from top is counter clockwise from bottom).. But the cool fact is that they seemed to be feeding each other.( Each other ?!!!!?😅 As they are two faces of a single vortex).. And u cut half and it destroyed.. But here two different vortices collide with each other in a head on collision forming another sets of vortices.. I m a fan of her channel too.......👍
It looks like the first rings edge breaks into multiple sections (clumps) . The wavefronts lower pressure side helps keep the material moving outward. The action that creates the second rings is that the clumps inside high-pressure area are naturally going to the low-pressure wavefront. As these clumps are somewhat spherical at this point the resultant action is that the clumps inside moves outward from the collision area. This, in turn, makes this spherical structure turn inside out. This action of the clumps insides going outward and the edges of the clumps moving slower means once the material has distorted enough the outside will be sucked into the inside from behind these rings (closest area to collision area ). This makes it own little vortices which appear 90° rotated. As an extra note material is still fed during and after this to behind the secondary vortices and this material is fed through the center of the vortices as well adding to the vortices rotational speed and velocity. The rotational speed helps stabilise the vortices and allows them to persist for longer rather than dissipate. You can see these steps happen if you slow down the time and focus on one clump. I think a good follow up would be to try using different fluids other than dyed water (one that doesn't mix with water) and see how this changes the timing of different stages.
Yes, the smush re-vectors the momentum radially. After that, faster velocities (they shoot the vortices at different velocities because of squeezing harder) of the expanding ring, creates a faster 'rate of increase' of an already ever increasing reynolds number (of the expanding ring). Once the flow 'trips' over into becoming turbulent, it creates high and low pressure areas. The low pressure areas along the radial, create fast moving flows that move towards the high pressure areas. You can see this as the die moves tangentially to the wave front. The low pressure flows come from both directions, clockwise, and counterclockwise and meet 'behind' the high pressure part of the wave front. Both of these flows now act as NEW jets that meet and form short lived new vortices. The reason the new vortices are short lived is because the flows already have a high reynolds number (are in various aspects of turbulent flow).
IllisMoreo 87 There the particle accelerator made by SERN. Theoritacally its supposed to make an artificial black hole but they never activated the device they made.
Yes. Stuff like this is how we evolve. Yes, in a combustion engine, the explosion difference could be tremendous giving more horsepower, better fuel mileage. Problem is that piston coming up. There's really nowhere for the second output to have the spread out flat and evenly across the top of the piston that would make it that much greater. Would have to be dead on and spread it out flat covering the top of the piston. Then you have firing, which again is like the piston, where the plug would have to set to fire in the center of the fuel meeting and follow outward with the process. Fire in the dead center, the explosion would form in the center, chain it's self from there outward, covering the whole piston top giving more power through a multiple combustion series and require less fuel. Then you have timing. That's a whole other problem to get straight. Do you fire before, during or after contact? Computers should make easy work of that though. I like where your mind is headed with it regardless.
Oh wow. I interpreted his comment as literally scale it to the size of a car, not scale it to be used in a car. But I really liked reading your thought process :)
Nah I think he meant, scale the mechanism up to a size that would produce those water donuts close to the demensions of a full size car, in order to enable you to see higher detail close up, as to what is really happening during the collision. I would assume he didn't say anything to the guy with the elaborate engine application perception, because it was much more interesting and impressive of an idea and he'd rather just keep quiet and accept credit and applause, then explain his original intent.
I freaking love this man, he said "I used some Patreon funding" like he was ashamed or something. He could literally ask for anything and get it but he wont. I can only hope that this is what the creators of RUclips had in mind before Google bought them out If this man turns out to be a fraud I will lose hope in humanity.
Well it could be looked at in the way he had to use his Patreon money, which pays his rent/bills/food expenses on supplies for a video. I'd be a little bummed too.
You are so right . It's all about persistence...my vortex was making pulled noodles and after months / years of practice it finally worked out. Cheers, Michael

hey you know how tornado's being created right with hot and cold air what if you would heat up the red liquid and cool down the blue or something like that it sound better in my head but maby you could do something with this
Destin do a video on mechanical face seals, and gas compressor seals. I work for a company that designs and manufactures them. The gas compressor seals are flat to within 2 millionths of a inch and use a design to create lift between the rotary and stationary faces with no contact. Sealing hundreds of bar. We measure their flatness in helium light bands.
So I was looking at the shots you made and I notice that they are not just secondary rings but 1/2 blue - 1/2 Red and that they don't mix. So the pressure wave from the 2 are causing a form of kenetic barrier with the weaker eventually breaking down. The density of the 2 liquids are not equal. But none the less brilliant...
You are an amazing person ! I like your work , and , i can't donate you but if i can , i want to do that ! it's also a scientific channel and moral based for the life !
Even the ones that didn't get the results you were looking for were still beautiful. Which means, that there's still beauty, even when you fail. Further encouragement to not give up! Thank you for sharing the results of your experiment! (I'll even overlook the fact that you pronounced "gif" with a soft "g" :P)
Thank you to the Patrons of Smarter Every Day for helping me do things like this: www.patreon.com/smartereveryday.
Think about the spin of each ring. See the mushroom cloud effect at the start? The centers of the ring are moving outward faster than the outside and creating a backspin. When they collide, even as the low pressure pulls material together, both rings are still spinning opposite each other and because of the magnus effect(if I'm thinking of the correct effect), they create a forward, or outward away from the main ring, pull. I can't articulate it very well because I'm just not smart enough, but think of a basketball's backspin, and how it creates a forward pull that lengthens a shot.
SmarterEveryDay Bro, did you just say “jif” !?!? Graphic Interchange Format... “gif”. You are a true hero to my girls and I and I have been subscribed for years, but that is unacceptable. 😂
...and then not using Micah 7:8 for your Bible verse? Perfect video for that verse!
God bless you brother. Keep up the great content.
Maybe there is a direct collision between an area in the low pressure zone and in the ink or the space between that causes the smaller rings to be at a 90 degree turn.
Could the reason for the 90 degree turn be due to the low pressure zone pulling material to itself then the momentum carried from the movement colliding with the material from the opposing side create a backspin and then create a new vortex
I dont think there is an actual 90° turn. Looks like many smaller collisions similar to the first. Like fractals. Id love to see this done in a place with 0 resistance if it were possible.

It would only be better if it was recreated in wewd. ;)
May sound like am over simplifying it but Vape Tricks are full of stuffs like these lol youtube it?
We used a computer controlled cylinder to pump fluid behind a rubber membrane to fire toroidal vortices out of the vortex cannons.
We fixed one of the vortex cannon in a stationary position, and used a multi-axis microscope stage to align a second cannon to it… which sounds incredibly easy, until you realize that
DYE density was an experiment all on its own.
If the density of the dye mix was lighter than water, the vortex would go up.
If the dye was more dense than water the vortex would fall.
We had to overcome SO MANY VARIABLES and we basically spent about 4 hours figuring each variable.
Water/dye temperature differential
Water turbulence
Water turbidity (cloudiness or haziness of a fluid)
How to reset the aquarium
Cannon Spacing
Cannon Nozzle
Cannon Shape
Dye homogeneity in the vortex itself
The piston displacement volume
The piston stroke speed
Rubber diaphragm tension, would make one side fire faster than the other.
Water or air to drive diaphram?
Firing speed (too slow and they drift, too fast and turbulence tears apart secondaries)
We did a complete redesign of the cannon 3 different times.
The Dye loading method was changed several times
At times We tried to maintain negative pressure on the cannon chamber… we also tried to put shutters on the front of the muzzle. Ultimately I decided it was ok to live with dye dripping out of the front.
We had to premix the dyes and eventually we got there.
It got to the point where we didn’t even really know what success looked like and always thought we were there.
Could you please enable the english subtitles ? Thanks.

I see in 30 years (or around then) vlogs will be immersive and participatory, and movies will allow you to enter into the storyline and observe the characters side by side (or be one). We do have that to some extent with video games, but in 30 years I think VR will encompass video games, movies, online media, news, everything. I think anything media related will be participatory and interactive from a virtual reality standpoint. The camera's wouldn't just be 360 capture...they'd be able to map out 3D space and reproduce any environment for us to walk through, or fly, or shoot zombies, or have a virtual significant other that makes you happier than any real person you've ever met. "Hey, you talking to me?" "Nah, I'm just having a conversation in the Matrix."
Of course that's assuming we don't blow ourselves up first.

My thoughts exactly. Thinking of 1.618 phi golden ratio, DNA/RNA helix, Ein-Sof, and Carbon 7. It does require much control or perfect observed conditions, of which chaos can interfere with greatly.
so..... what exactly do you mean by forwards? I can see many things in the human world that was supposed to pull us forward, they mostly ends up enslaving us in one way or another.
Figuring out new information, developing new technology- it's what keeps civilization advancing. It's how we become more and more advanced.

@@StanHowse yes lol
Many years ago I did some research on thermoelastic effects with concentric discs. One unexpected effect we found was that the many round hot spots that formed always were a prime number. Varying condition we got from 3 to 23 evenly spaced spots. I would like to know what number of ring spots you generated, and what influenced the number of these rings.
Interesting...... Do you know how/why the rings form?
Chris Heichel In my research, it was thermoelastic instabiliy. Friction causes temperature rise, which causes thermal expansion, which localizes heating to a narrow band. The higher the rotational speed, the greater the instability and the quicker the hot spots form. We even found that a plain paper ring could form hot spots on steel (blue oxide color) in about 0.7 seconds without even discoloring the paper!
@@arnoldanderson7661 Thank you! It looks like it's going to make for some very interesting reading. I look forward to learning more about it.
Since the pressure differential inside and outside the ring would be consiastent around the whole ring, the ring being symmetrical, then it seems feesible that the collapse would break into the lowest possible whole number larger than one, at intervals informed by the dimensions and momentum of the fluid. The rings in the video I mean.

“I started this process simply wanting to re-create something that captured my imagination, but obviously it morphed into something much larger than that.

Honor for this channel for not hiding the payoff behind ads
Agree or not, this is the most beautiful video on RUclips.
Mohamed Doha or not
pretty much tied up with Brian Cox's gravity experiment video. both videos fill me with a indescribable happiness
I wouldn't say its the most beautiful video on youtube thats just your opinion and others might agree. But what I would say is that its sad this video wont get the popularity it deserves. RUclips was made for videos like this but now it just seems like they've forgotten where they came from
The thing that i love the most in science is passion... when a scientist dedicates 3 year of his life to see "just ink in an aquarium" and get motivated to try over and over again with no garantee that this experiment will turn into something usefull or even gonna work this gives an amazing lesson.
Passion is what really motivates people and it's real.
Some times i forget about passion's existence this is why i felt so good watching this video, made me remember this is possible and if i'm not feeling that at the moment i just need to find my two vortex colision somewhere.

If Pythagoras were alive today, he'd be asking 2 very obvious questions:
"Why Are There Always 18 Rings That Form After The Collision?"... "What Can We Learn From This Numerical Constant?"
Please, see for yourself - pause the video during each take and count the rings that form.
18 lateral rings are formed after each successful dynamic collision, time and time again.
18 is the constant, but why is this? What can we glean from this phenomenon?
I'd suggest that the number 9 may hold the secret to this mystery...
I'd really love to hear Destin's take on this.
Amazing video, as always!
RealityHijacked
I didn't notice until u said.....
Nice observation...👍
There may be a scaling parameter involved that involves the ratio of the ring diameter and the strength of the vortex. I wonder if varying one of these two parameters may cause tha number to change.
YES! Great question!
It's not always 18, I counted 28 one one of the 12 hour clips
+Eisen Feuer, was the 28-count an imperfect collision? The 18-count trend might only occur when then collision is flat. If that's the case, the angle with which the rings collide might be influencing the number of lateral rings.
Three years for one video... if this doesn’t drive home the point as to how hard, long, tedious, and ultimately rewarding it is to pursue and share knowledge, then I don’t know what will.

Fluid dynamics are fundamental in spacecraft propulsion. Understanding how this effect works, and being able to recreate it successfully 100% of the time might one day help us to colonize Mars or create a habitable artificial gravity aboard space stations.
I add that last bit about artificial gravity because the Coriolus effect is a big hinderance to creating smaller scale rotational g force - imagine if we were to apply this fluid dynamic effect into the equation for coriolus to off-center the fulcrum ten inches to the left effectively canceling out the big g on the y axis - how awesome would that be?

QuasiTron Gaming I agree. I always find these ‘what’s stopping you’ lectures very played out and condescending. What’s stopping people is money, or time, or maybe their dream job just isn’t economically viable. Maybe someone’s dream is held back by their genetics.

Anonymous Freak isn't he the guy that said we have never been through the van Allan belt, and we no longer have the technology to go back to the moon,
Um.... No. He said that we "lost the technology" to go to the moon. Not that we haven't been through the Van Allen belts. And he was being largely hyperbolic about the "lost the technology" - not that we COULDN'T get back to the moon, just that we stopped making the stuff needed.
And both "quotes" aren't actual quotes by Pettit or another NASA engineer, but science-doubters misquoting/misinterpreting them.
Anonymous Freak I've heard him say it, your a liar sir, do you work for fake nasa? You gotta be pretty thick to think that nasa stopped making the technology that sent them to the moon and made "history"
Why would NASA keep making now-obsolete technology? The F-1 engine (the engine of the Saturn V) hasn't been made since the mid '60s. The AGC (Apollo Guidance Computer), in addition to being ridiculously out of date, hasn't been made since the early '70s.
Yes, we *COULD* build technology to go to the moon again - such as SLS or BFR, but it isn't available *NOW*. After Apollo 17, there was zero reason to keep making "moon technology."
Anonymous Freak ok it's not moon technology its space technology, and don't tell me they wouldn't keep updating their technology?? The gasoline engine was built over 100 yrs ago but they keep updating the technology don't they. Plane technology is kept updated all technology is updated, but not moon technology???

I didnt dislike it, but i understand why others do. We didnt learn anything new from this video that we didnt know from the potato camera video. We have the same questions. He did not unveil the mystery. he just recreated the same thhing
Major Tom recreating the same thing in a better footage could lead to a better theory and solve such mystery. That's the point of this video.
Neutron star it was too much time invested in something that may or may not be solved and which purpose is just curiosity rather than something transcendent like finding a new method of renewable source of energy, a cure for something etc...
-Major Tom- I'll be lmao if in 20yrs this leads to faster and safer planes or increase in wind turbine effeciency
Major Tom this is literally studying fluid dynamic, 4 years is a joke if you want to compare it with some other experiment that took decades. Also some other scientist are working on that not Destin. Its not his expertise.
so this is what fluid dynamics looks like in slow motion, one of the best vids since if first learned about fractiles, I'm hanging on to this one.........
Shows image in Thumbnail... starts video with image! 1 million upvotes for this!
I, like you, am fascinated with fluid dynamics. You and others may be interested in a study by NASA and the FAA in the 1980s to study vortex turbulence caused by aircraft, and the effects on other aircraft.
To me, the effects of wingtip vortices on other aircraft was a no-brainer. These effects were the focus of this study on aircraft safety, while little attention was paid to the generation and propagation of the smoke streams used to make the vortices visible.
At the time, I was involved in Unlimited Air Racing, and could usually be found at an airport, looking up. One of the usual suspects in air racing had contracted to fly his Hawker Sea Fury for the study to generate the vortices to be studied. They did this with wingtip mounted smoke generators developed by the government in secret. These were no ordinary smoke bombs nor fireworks, but used a secret formula to create the longest lasting aerial smoke trails ever seen. It reminded me of solid fuel rocket smoke. The Feds insisted on mounting and un-mounting the pods themselves behind closed doors.
As you would imagine, as the smoke streams left the wingtips the spinning vortices became immediately visible. The objective was to fly another aircraft through the vortex turbulence and to note effects on that aircraft.
Well, as happens with boys and their toys, the pilot of the smoke plane decided to fly his Hawker through some basic aerobatic maneuvers. Those of us watching have seen some of the best pilots ever to fly do these maneuvers flawlessly, but this time was different. Because of the extra dense and long hang time smoke of these generators, the spinning vortices did something incredible. As the vortices moved closer to each other, they began to unwind. Then astonishingly, the two smoke streams joined into single giant smoke rings, their diameter being equal to the wingspan of the plane.
The formation of both the vortices and development of the final rings is very much like the effects noted in your experiments.
Keep up the great video work, and stay curious!
peace-out Tc
What you describe is an incredibly dramatic occurence of a well-known vortices instability named Crow Instability. Your analogy is spot-on, here: this is exactly what is going on in this video, with the two elongated contra-rotating vortex rings acting like two wingtip vortices. You see the same phenomenon quite often ensue in contrails, in clear skies. But not as dramatically as the occurence you describe !
Anyway, from a Physicist to a plane enthusiast: great intuition !
Does any video still exist of this event?

I haven't yet found any super-secret smoke generator footage (the event Tom described), but I found this...

The best questions in science lead to more questions.
Hi Sunshine, I have been watching videos on vortex in water the one that caught my eye was when a girl took a 12" plate in at the shallow end of a swimming pool and with one swoop down created two vortex. These two vortex started swimming laps together they lasted so long. I couldn't believe it one little swoop well over 3min. I thought that was cool until I watched watched this two colliding vortex producing baby vortex, I'm still replaying this in my mind. May peace an prosperity be with you always.
That girl was PhysicsGirl - Dianna Cowen
Steve-o
yeah I watched that episode of physics girl too....
But the case here is different from there.
There is a toroidial semi vortex with two openings rotating in opposite directions....(it seems pretty obvious ., As clock wise rotation from top is counter clockwise from bottom)..
But the cool fact is that they seemed to be feeding each other.( Each other ?!!!!?😅 As they are two faces of a single vortex)..
And u cut half and it destroyed..
But here two different vortices collide with each other in a head on collision forming another sets of vortices..
I m a fan of her channel too.......👍

this looks like the answer!
That was beautiful.
To me it makes me think the way the universe was created, through massive collisions and explosions. Really cool work. Kudos.
It looks like the first rings edge breaks into multiple sections (clumps) . The wavefronts lower pressure side helps keep the material moving outward. The action that creates the second rings is that the clumps inside high-pressure area are naturally going to the low-pressure wavefront. As these clumps are somewhat spherical at this point the resultant action is that the clumps inside moves outward from the collision area. This, in turn, makes this spherical structure turn inside out. This action of the clumps insides going outward and the edges of the clumps moving slower means once the material has distorted enough the outside will be sucked into the inside from behind these rings (closest area to collision area ). This makes it own little vortices which appear 90° rotated.
As an extra note material is still fed during and after this to behind the secondary vortices and this material is fed through the center of the vortices as well adding to the vortices rotational speed and velocity. The rotational speed helps stabilise the vortices and allows them to persist for longer rather than dissipate.
You can see these steps happen if you slow down the time and focus on one clump. I think a good follow up would be to try using different fluids other than dyed water (one that doesn't mix with water) and see how this changes the timing of different stages.
Yes, the smush re-vectors the momentum radially. After that, faster velocities (they shoot the vortices at different velocities because of squeezing harder) of the expanding ring, creates a faster 'rate of increase' of an already ever increasing reynolds number (of the expanding ring). Once the flow 'trips' over into becoming turbulent, it creates high and low pressure areas. The low pressure areas along the radial, create fast moving flows that move towards the high pressure areas. You can see this as the die moves tangentially to the wave front. The low pressure flows come from both directions, clockwise, and counterclockwise and meet 'behind' the high pressure part of the wave front. Both of these flows now act as NEW jets that meet and form short lived new vortices. The reason the new vortices are short lived is because the flows already have a high reynolds number (are in various aspects of turbulent flow).
*accidentally makes a black hole*
IllisMoreo 87 There the particle accelerator made by SERN. Theoritacally its supposed to make an artificial black hole but they never activated the device they made.
IllisMoreo 87 it's a joke bud
Omfg. It was just a joke
Dreamer King , gravity is a made up term gravity doesn't exist.
Wooooshh
I really like this, I think this could be scaled up to car size and we will see some truly amazing things
Yes. Stuff like this is how we evolve. Yes, in a combustion engine, the explosion difference could be tremendous giving more horsepower, better fuel mileage. Problem is that piston coming up. There's really nowhere for the second output to have the spread out flat and evenly across the top of the piston that would make it that much greater. Would have to be dead on and spread it out flat covering the top of the piston. Then you have firing, which again is like the piston, where the plug would have to set to fire in the center of the fuel meeting and follow outward with the process. Fire in the dead center, the explosion would form in the center, chain it's self from there outward, covering the whole piston top giving more power through a multiple combustion series and require less fuel. Then you have timing. That's a whole other problem to get straight. Do you fire before, during or after contact? Computers should make easy work of that though. I like where your mind is headed with it regardless.
Oh wow. I interpreted his comment as literally scale it to the size of a car, not scale it to be used in a car. But I really liked reading your thought process :)
I thought he litterally meant use cars instead, but I guess some people are just not retards.
Nah I think he meant, scale the mechanism up to a size that would produce those water donuts close to the demensions of a full size car, in order to enable you to see higher detail close up, as to what is really happening during the collision. I would assume he didn't say anything to the guy with the elaborate engine application perception, because it was much more interesting and impressive of an idea and he'd rather just keep quiet and accept credit and applause, then explain his original intent.
@@MrJadedGreen That being said, I have no idea how you came to the conclusion you did, and I'm not even sure what you're trying to imply here..
Water company be like: “Jeremy owes us $1000, bill owes us $1000 as well, and Destin owes us $190,387,107
How is this disliked at all? Its great they produced a better visual recreation of a scientific mystery.
4600 potatoes hit dislike
I think bots are made to dislike random popular videos very quickly.
Probably because he said "jifs" instead of "gifs" at the end :)
I ask the same questions on puppy videos. Just why?
@@seungyuno Obviously they are a cat person
I freaking love this man, he said "I used some Patreon funding" like he was ashamed or something. He could literally ask for anything and get it but he wont. I can only hope that this is what the creators of RUclips had in mind before Google bought them out
If this man turns out to be a fraud I will lose hope in humanity.
Creators of YT has Benjamins in mind papa
Well it could be looked at in the way he had to use his Patreon money, which pays his rent/bills/food expenses on supplies for a video. I'd be a little bummed too.
You are so right . It's all about persistence...my vortex was making pulled noodles and after months / years of practice it finally worked out. Cheers, Michael
dude my jaw was on the floor - that was, in a word, stunning

If you'd like to help, it would be great to get some captions for this video in your native language. At this point, there's no English. Help would be appreciated! ruclips.net/user/timedtext_video?ref=share&v=EVbdbVhzcM4
hey you know how tornado's being created right with hot and cold air what if you would heat up the red liquid and cool down the blue or something like that it sound better in my head but maby you could do something with this
Destin do a video on mechanical face seals, and gas compressor seals.
I work for a company that designs and manufactures them. The gas compressor seals are flat to within 2 millionths of a inch and use a design to create lift between the rotary and stationary faces with no contact. Sealing hundreds of bar. We measure their flatness in helium light bands.
Hey if you need help with translating your videos into spanish send me a Dm on twitter twitter.com/InsaneStreamsPE
So I was looking at the shots you made and I notice that they are not just secondary rings but 1/2 blue - 1/2 Red and that they don't mix. So the pressure wave from the 2 are causing a form of kenetic barrier with the weaker eventually breaking down. The density of the 2 liquids are not equal.
But none the less brilliant...
You are an amazing person ! I like your work , and , i can't donate you but if i can , i want to do that ! it's also a scientific channel and moral based for the life !
Even the ones that didn't get the results you were looking for were still beautiful. Which means, that there's still beauty, even when you fail. Further encouragement to not give up! Thank you for sharing the results of your experiment! (I'll even overlook the fact that you pronounced "gif" with a soft "g" :P)
