Could you get the fully ring by doing this where water and oil meet?

[@ABitOfTheUniverse]

N3rdSci3nc3 If you had a piston come out from the side of the pool and a layer of oil, say vegetable oil, thick enough to incorporate half the vortex ring, then you could test it. However, I suspect that the differing properties of the water and the oil will lead to instability of the vortex. The difference in physical properties; like the viscosity, density and compressibility, and even the chemical properties; like the molecular polarity, will lead to one half of the vortex ring lagging behind the other half. Friction between the two separating halves will lead to a loss of angular momentum as the water half of the vortex acts on the oil not in the oil's half of the vortex and oil's half of the vortex acts on the water not in the water's half of the vortex. Though it wouldn't hurt to perform the experiment and see for ourselves. Might have to reduce the size of the experiment a little, or find some where where oil and water are already being stored together where an apparatus can be submerged that would generate the vortex. Any ideas where such an experiment could be performed?

Ok, this sounds good to me except for one thing. How much space time does a wormhole created like this cover. Physics Girl made a tunnel through the fabric of water and it wasn't a very long tunnel. The amount of energy required to create a wormhole that bends space time is astronomical, perhaps as much energy as exists in the entire universe.

[@dannyhoberman5384]

Except that the fourth dimension is time and you can't have time as a dimension in your "4d plate". Also, we need two media (one being the fabric of space-time) for this kind of an arrangement, and last I checked our universe has only one. But the Idea is still open to future discoveries.

[@Sketchicane]

ive done this with a much larger plate with a sharper concave edge, and i love colliding the half rings. if you do it just right, the spots will start to spread out, then seem to get so close that they seem to swallow each other up, and then dissapear. at night sometimes bubbles get caught in the collision, and it highlights the vortex line with the pool light, and the vortices sometimes expand to over four feet in diameter before "exploding". another cool thing that happens when the dips get really close is that they get deeper due to the faster spinning caused by the stretching half ring, and makes a weird gurgling noise. its quite fun when you are bored and you dont like cold water. :)

Wow that's awesome! I thought I'd know a lot more about these than I apparently actually know. The food-coloring experiment was pretty epic. I had no idea that these things take matter with them. (In retrospect it should have been obvious though, given that that's precisely how smoke rings work) Really nice experiment

[@physicsgirl]

Thank you. :) I was pretty shocked at how well that worked. I thought it might swirl around for a while on the surface or even get left behind, but it traveled down through the whole ring and stayed like that for a while.

[@wbeaty]

> oval or a square? kiysiy or a trefoil knot. Search on vortex knots

[@Kram1032]

kiysiy preservation of angular momentum, mostly. If you push water with a plate, it flows past the edge in a way that makes it rotate. You put angular momentum into the system (to do so, you must do work - not work in the everydaylife sense but in the sense defined in physics, but in this case the two concepts allign nicely) and that is one of the quantities which is always preserved in a free system (i.e. a system no work is performed on). The conservation of angular momentum explains why it is so stable. And the shape comes to be because we are talking about rotations here. Square vortices generally don't form. Elliptical ones could form, I guess. And under special circumstances (seem for instance, some of the vortices on Jupiter) they may be hexagonal.

[@wbeaty]

Kram1032 Well, net angular momentum of the system is zero, and the dinnerplate isn't being torqued. It's like spinning up many pairs of flywheels, each CCW has a CW to cancel. But the net linear momentum isn't zero, so if you were floating in the pool, the Falaco half-ring gets momentum x, and your body gets equal momentum x in opposite direction. This illustrates that "vortex shedding" is the origin of thrust of propellers, rowboats, fish, and aircraft.

[@Kram1032]

wbeaty Is it net-zero? Obviously, if you only take the cross-section that is visible on the surface, the two disks rotate in opposite directions so their combined angular momentum is zero. However, if you look at the bottom of the vortex-half-ring, there you have a rotational direction which may not be cancelled out. - it depends on what the air flow above that does, I suppose. Though given that there is a medium change, I don't think the induced angular momentum completely cancels out. Since you do work on the system, I don't see why there definitely shouldn't be any. That being said, I can see the linear momentum being non-zero too. (Else, after all, it wouldn't move forward) and for a full ring at least, I can see how angular momentum overally would cancel out and only that momentum would remain. Now I'd love to see a version of this experiment where you can also see the air flow. I'd assume that an air-vortex would form just as well as a water vortex did in these experiments. However, I'd also guess that the air half of the vortex would move at a different speed (if it didn't, it would have two separate momenta for the different media which would be weird.) and it probably wouldn't be as stable?

[@Sancarn]

Physics Girl To be honest I am under the impression that there should be more of this kind of "explaining phenomena" in education. People should start with something like this and say "Why?" Then we learn the reasons why. Then we start to relate it to other things like tornadoes and smoke rings. I had no idea that smoke rings form because of this, nor that mushroom clouds form from the same phenomena. And I've got a degree in Theoretical Physics... xD I think education really needs to be revolutionised. But it's getting there I guess.

What I think is so great about this channel is not only the clarity of the content, but also that your enthusiasm sort of gives us permission to get excited about it with you, if that makes sense.

(With the stipulation that i really don't know anything about fluid dynamics) What would be the effect of projecting a smoke ring along the meeting plane of air and a heavier-than-air gas, like Sulfur Hexafluoride?

[@TheRealSkeletor]

Beat me to it. This exactly.

[@physicsgirl]

Thank you! Honestly, I don't know much about fluid dynamics either. I think it's one of the most difficult branches of physics, and most undergraduates are not required to take any fluid dynamics classes. (I wish i had taken one in undergrad!) That's a very interesting question though. I would assume the vortexes would move at different speeds because the viscosity for the two fluid is different.

[@DANGJOS]

Physics Girl Yeah I was talking to my friend one time about how fluid dynamics, a seemingly important branch of physics, just doesn't seem to be required in undergrad or graduate school for physics. Engineers are the ones who take it. I'm still in undergrad (physics) perhaps I should consider it.

[@TheinMoka]

This would be a neat experiment. I'm not fluid dynamics expert at all, but I can imagine that if the two fluids are at rest and that you're simply moving the ring as you've described, there would be a difference in the vortex speed, but the resulting difference may skew the ring out into a line, and possibly rotate it completely and repeat. I'm thinking of a ring forming into a line, then forming into a ring again, etc. and that's because there is no net external torque, so angular momentum is conserved, thus if the system rotates partially, it must rotate completely to conserve momentum. I think the reason we have a half ring in the video is because of the extreme case, where the bound viscosity difference is so much, that there is no angular velocity for the ring system itself, but given a critical viscosity ratio between the two liquids, there may be a case which the ring forms and reforms. Not sure! Fascinating question though.

[@gasparmc]

Woah, you actually put some ink to reveal the invisible spinning connection, I was craving to see that somewhere. So cool!

[@abstract_ion]

From my observations, what's happening is that when the change in velocity creates a shear there's also a change in pressures whereby the vortex formed is at a high pressure and as it diverges outwards from the root low pressures will rise and sink into the vortex to equalise the pressure. Chances are the reason it lasts so long is because of the volume of the pool that has to sink into the vortex; it has to match the entire volumes pressure for it to disappate. I might be wrong hen it comes to the pressure duration but the dynamics are similar to an anti-cyclone.

[@FrstPrnc]

Physics Girl, what if you try this with two fluids with different densities? Proverbial oil and water, could you have a half vortex at the boundary? Also awesome that when it hits the pool wall the volume stays the same so the diameter reduces. Great post.

LowFlyinGirl +1... - I'd go so far as to say "rare to see such a well educated youtube host" - gender has nothing to do with it. This show is incredible for a lot of factors. Host, content, delivery.

[@ThoseMadFoxes4330]

Woah! That makes me wonder; if a dish-shaped solid were to “scoop” through a bit of our atmosphere from space, it might create a HALF RING TWISTER! And based on the inherent stability of the circular motion, the twister might go EXCESSIVELY FAR!! Do you think that’s possible? Or would it have to be a more dense medium like the water?

[@illblues1072]

I’ve had this in my watch later list for months, I love it & thank you for making people love physics, it’s one of my favorite branches of science

[@pisepranavramesh9574]

method of explanation is so good.

[@FRUHD]

I hated physics. The only thing that I liked about physics class was when it ended early. But this. I watched and the jaw dropped and I literally said out loud, "woah, cool" right before you said it in the video. So. Awesome.

[@physicsgirl]

I hate to break it to you, but this was a physics video. ;)

[@FRUHD]

Physics Girl and it was waaaaay awesome xD

[@Siberius-]

FRUHD I think what you are refering to.. is boring teachers who probably hate their job and aren't very good at connecting with the brains of their students.. they make science boring.. but then you look at Vsauce and shit.. and young people are very interested in science, but only if they have a reason to be interested.. otherwise it's boring. (A lot of science teachers aren't even scientist, they just read from books and stuff, and the ones who are scientist.. don't get paid as much as they should, and they get payed the same as the other teachers when they're the ones missing out on money to educate kids).

[@tjstevens8878]

It’s not a wave… it’s a pair of entangled particles.

[@deluxeassortment]

You didn't mention one cool thing: If you cut the vortex in the middle with the plate, they dissipate immediately. Also, would this be analogous to entanglement?

I think this may also be this vortex, but I'm not certain. I moved my spoon through my coffee this morning, where the rounded side was going against the water, and two vortexes formed on either side. They of course didn't last, but that's really cool!

[@solev6859]

its like a worm hole in space connected to each other

[@okccuster]

And maybe related to quantum entanglement also.

You can do this at home in a cup of tea \ coffee etc (if its a big enough one) using your spoon in replacement of the plate.

Can we make a connection of wormhole with this?

[@imaginaryuniverse632]

Apparently until it contacts a boundary of a different medium, water through water, air through air, space through space. I think space is where the greatest potential is and the question is how exactly to create the vortex. I think the answer can be seen in Giza but I don't know if it can be understood exactly. It seems to work as the electron transfer chain in our mitochondria most apparently with the slabs above the King's chamber resonating as the enzymes that attract the electrons in our cells. It may sound crazy but I am pretty sure it's correct.

[@alexwang982]

[@padddy48]

i think we cant create them, i think they had to be made with the the big bang since you need that movement at the beginning? i dont know haha

[@mlliarm]

They look like two black holes connected with a wormhole...! (I wonder if there would be any connection).The demonstration of matter exchange between the two vortices was amazing !

[@jollyzypyk7263]

if you want to see the whole ring in using two different mediums ( water and air) try using something a bit closer to the density of water, like oil, so you have water and oil, the whole ring should be there in the water and air but since food coloring cannot float in air you are unable to see it. so by using oil which is closer to water the food coloring should show the entire ring

[@Rapbando]

Well you tell how it formed but not why it lasts so long and the main reason you didn't, is because mainstram science cannot admit the natureal laws, because they would reset the matrix.

[@AndrewKaylor]

now, make a worm hole and I'll be really impressed :)

Maybe this is how to create a Worm Hole in outer space? The dark circles remind me of Black Holes in space.

[@carlosrodolfo2019]

1) Regarding this video, do what follows: a) write the density Lagrangian and the equations of motion of the vortex; b) consider now dispersive media; c) solve the equations.
