Why we typically don’t talk about angular momentum in fluids.
physics.stackexchange.com/que...
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 light 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 to overcome 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.

[@johndiggle6315]

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.

[@BLOODnVALOR]

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.

[@BigRheno]

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.

[@collinjenkins4651]

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

[@russellwile5694]

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.

@@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.

[@EdRickerVlogs]

@@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.

That moved me. I can't say why really. Brilliant!

[@TheOriginalFaxon]

BROOOO i remember seeing this in the early 2000s when it got reposted on Ebaumsworld, I'm stoked you finally filmed this properly

[@AnonymousFreakYT]

"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

[@kelnick2264]

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,

[@AnonymousFreakYT]

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.

[@kelnick2264]

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"

[@AnonymousFreakYT]

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."

[@kelnick2264]

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???

Agree or not, this is the most beautiful video on KZbin.

[@CountessVampire]

pretty much tied up with Brian Cox's gravity experiment video. both videos fill me with a indescribable happiness

[@prometheus2513]

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. KZbin was made for videos like this but now it just seems like they've forgotten where they came from

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.

[@guyjameso]

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?

[@plugs313]

Then you really didn't get the message, did you?

[@piratekit3941]

It might have been a project of persistence, but the end result was art. To consistently recreate the effects was no different than an artist spending 3 years on a painting. Beautiful!

[@Michael-se6om]

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

One of the most satisfiying thing I've ever seen, Thank you guys :)

[@arnoldanderson7661]

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.

[@christianheichel]

Interesting...... Do you know how/why the rings form?

[@arnoldanderson7661]

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!

[@christianheichel]

@@arnoldanderson7661 Thank you! It looks like it's going to make for some very interesting reading. I look forward to learning more about it.

[@benwilms3942]

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.

[@dredrotten]

@@benwilms3942) You need to learn more on physics and the English language before you comment on subjects such as this.

[@TheHandToolery]

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.

[@amandawright5170]

Absolutely beautiful and inspiring! The persistences is astounding!excellent excellent job very beautiful I'm sharing this to everyone i can!

[@DuckyBee156]

That. Is. Beautiful. Disregard the wonderful physics happening to create it, visually... I've replayed this time and time again.

[@RealityHijacked]

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!

[@shubhamsarkar9680]

RealityHijacked I didn't notice until u said..... Nice observation...👍

[@agmessier]

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.

[@JoDidntHearYou]

YES! Great question!

[@EisenFeuer]

It's not always 18, I counted 28 one one of the 12 hour clips

[@jerome_david]

+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.

[@jeremythompson9319]

I love that the secondary rings are 90 degrees out of phase with the initial ring. Well done!

[@icekk007]

The system starts with two vortices. After they collide, the vorticity has to go somewhere, which ends up with those beautiful secondary vortices. Fantastic!

[@LeiosLabs]

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!

[@eduardolima5495]

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!!!

[@tenkindsofpeople3679]

I knew you guys went top shelf on the music in this when it was released but had to come back to rewatch after the NDQ episode.

[@alexkram]

I love fluid mechanics too. Before studying fluid mechanics I had no idea how ubiquitous and important vortices are. Conservation of angular momentum is cool to visualize. Thanks for the great message about persistence and also for the gorgeous footage.
