You always create physics, your movement, your speed. Its all science.
Some years later, you sure did.
i think you did. 😊🤘🏻

Physics Girl - I've just found this video and it's brilliant! - I'm going to show it to all my pre-university and university level students when they are starting their learning for hydrodynamics. Many Thanks
Wish they'd shown me videos like this when I did my GCSEs!
Physics girl: try this at home when you're pool is too cold to swim in.
Me: I've got a pool? So Cool!
Yes many things to ponder
Am I only who was expecting a line below "I tried this and it works" instead I have a pool?

A bathtub, maybe...?!
I've seen it in a tub
This is why I signed up to do Theoretical Physics at University.
This is exactly what we didn't do during my course on Theoretical Physics at University.

WOW where di you find all these people who are actually interested in learning something!!?? Well done!! Nature is AWESOME cool Vid!!
I didn't know that the two vortices are really the two ends of a spinning tube. It nicely explains why they come in pairs, and the idea of using dye to make them visible is clever and beautiful. I learned something really neat today!
Yes I wonder if it’s how wormholes in space work!!
Same!! 7 years later though 😆
@@eduardodemedeiroscarlos5175 I think it goes much deeper than fluids. I suspect something analogous to this underlies entanglement and other quantum weirdness.

Could you get the fully ring by doing this where water and oil meet?
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?
So cool. I'd try it, but I live in the UK where we don't have outdoor pools. Or sun.
It is hard to concentrate on the physics when the nature's beautiful creation is in front of you. That is why perhaps we do not often find beautiful professors :D
It would be interesting to take a massive plate and do that in an olympic size pool to see how big the shadows would be!

It's the secret to creating wormholes! All we need is a 4 dimensional plate and we can make a tunnel through the fabric of space and time!
Jacob really....
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.
Looked like the tunnel was longer than the distance between point and point b
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.
but i don't think you will be able to find negative energy in your garage.
That's not what I was expecting when she added the food dye
It's not food dye it's food coloring silly

wait but how do you fit a plate in the bowl
I've just discovered you through reddit. How do I not know about this channel yet? You're one of the best teachers I've seen and I've had some amazing ones.
Woah, you actually put some ink to reveal the invisible spinning connection, I was craving to see that somewhere. So cool!
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. :)
really nicely done - love the food coloring trick to see the connected half-vortex ring structure. Might be cool to try two different food colors (e.g. red and blue) in either half and watch the slow mixing (what causes the tangential transport along the vortex line? gravity/sedimentation?)
That's a great suggestion. Will have to try it soon.
just found your channel out of nowhere . I love it so far. Great content, you hooked me with the water vortex video. im always curious. physics can be so cool.
Glad to see that this cahnel is growing so fast. Good job, Physics girl!
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
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.
> oval or a square?
kiysiy or a trefoil knot. Search on vortex knots
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.
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.
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?
So in order to stop hurricanes we just need to destroy god's plate.

It was :) But it represents the awesomeness of science just so well... maybe it could be your catchphrase!
Excellent. This is the kind of physics teaching that I really like, everyday physics with deeper implications. Love it.
I just learned so much from this video😊 It helps me understand lift and wake turbulence from the vortices that planes generate.
WOW -- Thank you for posting -- THAT was fascinating !
I was completely unaware of this phenomenon until now. Holy crap, science is so cool.
After watching this, I signed up for Physics next term at my school. Thanks for the push! I was on the fence, but I'm excited to take it!
That's awesome! Don't get discouraged if every class is not as interesting as this demonstration. If you can get through the boring classes there are countless phenomena like this one that can be understood and if nothing else, appreciated.
Jacob Beckey Great advice. At times, it's a struggle to understand the math and the concepts behind physics, but once you do you can explain phenomena like this. That's what's great about trying to understand the world.
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.
Sancarn Totally agree! If schools approached education like this, we'd learn a lot more as kids.
that was beyond cool! in 2.5 minutes you expanded my knowledge of tiny vortices by thousand fold.
That was really educational. I _thought_ I knew why the spots stayed together but I had NO IDEA about the "half vortex ring" phenomenon.
My goodness it's so refreshing to have a video show off something REALLY fun, with REAL science that doesn't just dumb it down beyond recognition. The part with the food colouring was very surprising!

You're one of the coolest channels on YT 💯 ty for existing lol 🙏
I wonder if you did oil and water. If you could get two half vortices traveling at diferent speeds?
Why did I watch this video at 10:30pm. Now I'm looking at a big plastic tub and wishing I had food dye and more vegtable oil.
How am I suposed to sleep now?
make you some Flow-tubes Put one color in the oil and a Different color in the Water and
see but it might mix.
no the reason is oil is less denser water ,so you will not observe it,but if u take liquids of nearly same density and having considerable difference in their viscosities then you will see vortex line at an angle
Straight up made me spill my drink from laughter lol
beautiful water example of black holes/worm holes.
The vortex shows 4th dimensional perspective, and the shadows show the 3rd dimensional perspective!
Wow! I love this. thank you for being so incredibly brilliant.
Love this, great presentation, clear and concise
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 !
This experiment inspired us so we made pool vortexes and recorded it also!! :)))
But unfortunately, it wasn't sunny for us, so we had to put food coloring in to see the vortexes. :)
Um...Maybe You Right Rina
Nice Picture Rica Also
That was really really neat. I'm kind of curious how many takes it took to get that nice sharp pair of vortices. Seems like for every good take you'd get a bunch of unusable blobs and have to wait for the pool to smooth out.
Haha that's a good question. The pool smoothes out enough after a minute or two. The wind is the real issue. The very first one I made was really good, but of course I wasn't filming. Then it was just a matter of getting the speed and direction of the "sweep" just right. :)
wow thanks for the explanation and the great effort making us this video! :)
Nice job! I perfectly understood everything you explained to us.
OH that's so cool! Thanks for the demo and the explanation!
That.... was... awsome!!!
Too bad we don't have many pools here in Norway. The public ones tend to have lots of pesky creatures with two arms and two legs that disturb the water..
What if there was a decent sized hole in the plate. Would you get four?
+The Federal Farmer yup
Could they move independently, though ?
+Sunomis yup
yes you will get four if the plate would have two extra holes and the extreme holes will spin in the same direction and the middle ones would spin in other direction but the intresting part is the diameter of the vortex is independent of the diameter of the holes drilled on the plate it is completly a function of velocity with which the plate has been pushed
The Federal Farmer that propbly could happen
I’m trying this in my pool tomorrow. Enjoyable video!
Karlee, Well done!!!! You understand physics better than any professor. I think you should be teaching the course. Great video to show non believers.
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.
Sun. Home pool. Clearly England is just not meant to see this.
All Countries You Can Do Everybody Has A Pool Exept for me :(

You can do it in a bathtub with a smaller plate.
I learned so much from watching this video it's ACTUALLY AMAZING.
I like how she is having fun translating the science into layman's terms for ease of understanding. Some people cannot even begin to wrap their mind around science.
For me personally, I was chastised as a young boy for using big words... when others had no idea what I was talking about... it felt like I was speaking a different language and it took so much longer for me to put the same concept into simpler words for someone who maybe hasn't read as many diverse subjects.
I grew up with an Encyclopedia Britannica set that was my internet before the internet.

You can get this process if you drag a spoon though a hot drink
In my case I use :
- Hot coffee w/ 3 tsp of honey
- Metal tsp
I made a vortex like this in some fresh cement when I paved my driveway, so now I can check it out any time; even if there is a lot of wind and rain! (well, not the dark spots on the bottom . . . )
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.
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. I actually have wondered about this a lot since the vortices are so stable, it is a lot of fun! Thanks for the great explanation, and a shout-out to #pbsspacetime for getting me here :P
Another really wonderful video, thanks!!! 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.
If I may, I'd like to ask a question related to your pondering on how to show half of a smoke ring. (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?
Beat me to it. This exactly.
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.
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.
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.
This was way more interesting than it should have been!!! Never knew about this.
I wish I'd seen this a long time ago as I have a smiliar experiment but using iron oxide magnetic salts with a spoon in a coffee jar!!! Thanks for the clarity
What if black holes are just vortexs
Why not be the first person to go into black hole and see if your theory was right.

Caleb Jones
Calm down. It was a joke.
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?
great experiment, very interesting. love the video.
Very cool and fun way to show vortices!
This effect is very cool, I couldn't help but think how this relates to space. If this effect could be replicated in the quantum vacuum of space, I wonder if it would create a wormhole and transfer matter from one vortex (wormhole opening / black hole) to another?
Just a thought...
+Akili Visual That actually seems plausible. The two largest hindrences besides the theorem would be the energy source to create such a vortex, and the ability of your cargo to survive such a journey.
Agreed
Just tried it thanks! Interesting to note that the vertical direction seems to have a big impact on the length of time they stay. I think they might go down and make the ring too diffuse. Also any wave action seems to draw energy out of the vortex.
Did it work for you? Yes, if there were any small ripples in the pool, it broke up the vortex quickly.
Physics Girl
It worked really well. I think the longest it lasted was about 1 minute. There were lulls in the wind, followed by gusts. Being a sunny day there were thermals lifting off every now and again.
Physics Girl
I just went out and tried it again today. Less wind. Vortex had no trouble going the length of the pool first try, however with the size of my pool that's only about 1 minute before it hit the far wall. Any underwater obstructions (stairs, my Girl's leg etc) disrupted it.
gasdive Awesome. :)
@@physicsgirl The whole thing reminds me of quantum entanglement. You created two "particles" out of a disturbance in the force ...egh field and those two were connected (coupled dynamics) and you actually showed the connection. Very nice. How about a video with similarities between fluid physics, matrix behavior of water droplets bouncing in the surface and quantum phenomena?
Just saw you on Seeker talking about Nuclear Energy and decide to check out your channel and this is the first video I watched. I'm hooked. Can't wait to watch more.
You can try this at night but maybe you won't be able to get those cooler dark spots.
But it would be awesome to see through a laser refracted through prism or something curved at end I mean you understand.
