Water rotation in two hemispheres and on the Equator
Вставка
- Опубліковано 19 вер 2024
- We have heard the theory: water going down the drain spins in different directions depending on which hemisphere you're in. But what if you are at the Equator and then move a few meters towards the Southern hemisphere, then move back towards the Northern hemisphere and try the same thing? Can a few meters make a difference? Watch this and let us know your thoughts!

The two scams of Coriolis effect: Shaped bowls and angled water pouring. In this case, it can be either, but it is most likely shaped bowls.
Shaped bowls: Pretty self-explanatory, when a downwards force pulls on the water, the water will move in the easiest direction the bowl allows
Angled pouring: Even if he places a middle blocker to "stop" the water, the water will still spin in their respective halves in the same direction. When he takes it out they will just recombine into a larger pool of water and still spin.
One thing that you should all realize without much knowledge at all, is the fact that move ONLY 10 STEPS from the equator IS GOING TO HAVE LITERALLY ZERO EFFECT AT ALL. *Crosses equator* suddenly feels how he is on the other side of earth because the spin is affecting him at a different angle by literally less than .00001 degrees. Like did you really think 10 feet from the equator of our 3958.8-mile radius earth is going to have such a monumental effect on water poured into a sink? (3958.8 miles is 20902464 feet, meaning 10 feet is less than .0001% of our earth's radius) Come on guys just think about it.
Makes sense to me. Way too close too equator to notice any spin either way.
Yep! As I said at: ua-cam.com/video/QTTJJAiQFRc/v-deo.html&lc=UgwdMVlWGZa5qM5AUll4AaABAg
" Yes, as others have pointed out, this is not really sufficient proof, though it's still rather cool. I recommend doing an internet search, it only took me a minute to find this: (Source 1) thegate.boardingarea.com/in-which-direction-does-water-drain-at-the-equator/ in which the author explains that despite videos attempting to show the Coriolis effect are often flawed. Evidence for the Coriolis effect is better shown in that hurricanes and tropical storms rotate in the opposite direction north as they do south of the equator. Another thing, the Coriolis effect would not be strong enough to make the flower spin *that* fast. Other factors play a more critical role, such as 1) bowl shape, 2) the way the water was poured
from source 1: “One of the biggest misconceptions associated with the Coriolis Effect is that it causes the rotation of water down the drain of a sink or toilet. This is not truly the cause of the water’s movement. The water itself is simply moving too fast down the drain to allow for the Coriolis Effect to have any significant impact.” which was found at (source 2) geography.about.com/od/physicalgeography/a/coriolis.htm, though it appears to me that it was since updated.
Source 2 also says: "The Coriolis effect becomes more extreme as you move further away from the equator toward the poles." thus, we would ALSO expect there to be very little if any difference from just a few feet difference!!
BOOM. Okay, so I hope that helps you viewers understand the situation a bit better :) have a nice day! "
So yeah, I found similar evidence. Good point about how little effect would be produced from that small distance from the equator!
Oh so that's how they did it! I remember once I heard about this and thought "yeah that makes sense!" but after years I also thought to my self "hold on there is no way this actually works" so I watched vertasium video about it and he confirmed my SUSpicion. But later on I still was thinking "ok but I know a guy that claims he saw it with his own eyes, so this must work somehow (by which I mean it either could have been just a trick or maybe unintentional thing like ground being tilted or wind blowing)" So it got me into looking for one of those videos. Also thanks for confiirming on how it works because I thought that these bowls are really SUS but they are too thin so there is no way for something to be underneath them that would sipn that water so I thought that maybe this guy spins the water with that blocker when he pulls it out. But it turns out my first SUSpicion was right and its all due to these containers. Also how did you know how this works?
also the bowl in the middle is a dead give away that this is a scam because if such a miniscule forces could determin wheather it turns left or right, that him taking that blocker should also make enough disturbance for it to turn one way or another.
The entire heliocentric charade is a scam.
You will find out soon enough
The best experiment would be to start draining in northern hemisphere and once the flower begins to cart the bowl with spinning flower to Southern Hemisphere. Will it continue stop or correct and spin opposite
ı think ıt wıll cdntınue same rotate cause of newton law of ınertıa
Look at all the panicked flat earthers...realizing that native gentlemen at the equator have a greater understanding of math and science than you do. Sad.
Shad Olson LOL, I hope you’re kidding as this is a scam.
I think you drain pan identifier is wrong. Water in the northern hemisphere drains counterclockwise. And in the southern hemisphere it drains clockwise. You need to switch the pans.
What if you switched the pans around? The flower seems to be spinning awfully quick.
This has nothing to do with location or the bowls.
Watch closely to the paddle he’s using to calm the water. When he wants the water to go left - watch very closely to the end of the paddle side that he’s NOT holding and it does a 1 second little “kick” left. Same to make the water go right. For straight down, he makes sure he pulls up perfectly with no kick. Tourists will buy anything.
Absolute nonsense. You must be a flattard. Nobody's so stupid as to think a tiny bit of movement of the paddle is enough to make the entire bowl of water spin down the plug in one direction. 🤥
Tell ya what dimwit, go pour some water down a plug in your house. Watch which way it spins. Then phone a friend who lives in the opposite hemisphere to you and ask them to do the same. I wonder what the result will be? 🙄
VodkaHindJelly He’s not a flattard lol... I mean, I like how you are mistaking actually rational people for flat-Earthers
@@ChristianJiang I've been to places where the coriolis effect is this strong. I've seen this effect with my own eyes. But even if I hadn't I would not immediately dismiss this video as some kind of fakery, which is what every single flat earther does.
So, give me a good reason to believe someone who claims that this is an illusion really knows what they're talking about.
VodkaHindJelly I’ve been to Kenya as well, while I was giving the tip to the guy who showed this, I told him that I knew the trick, but I wasn’t going to tell anyone. He smiled and accepted the money.
Also, go & watch Veritasium’s video!
@@ChristianJiang I've seen Veritasium's video - he confirmed the opposing rotation depending on which hemisphere you're in. He also did his experiments in a very flat pool with a tiny exit hole, so obviously there would be less swirl than if he'd done the experiment in a more conical container.
My toilet and my sink drain in different direction and no they aren't seperated by the equator. Its got more to do with the geometry of your bowl than anything else.
Certificate for crossing the equator line?
LOLOLOLOLOLOLOL. But hey, you gotta take da money from da tourists.
Coriolis is too weak to show in a drain. These are simply CW, CCW, and vertical drains. Fun though.
Coriolis is actually much stronger at the equator because the earth spins the fastest at this point (speed = distance / time). This is why sunsets are much faster at the equator than at the polar regions.
Yeah right, faster then a bullet, what a fool!
Please, the fact water will always seek the lowest point on earth, and that is always becomes horizontally level across its surface when it fills a void, disproves the water bulge needed to make a globed earth.
The Coriolis effect is strongest at the poles and weakest at the equator. Just a few feet either direction from the center line of the equator is too weak to have any effect on any rotation.
Indy Carr you're an idiot water is naturally round look at rain drops tears. And what do these drops of water do on a vertical plane. They ROLE down it because they are spherical.
Can you switch the pans?
This is staged for tourists. Contrary to popular misconception, water rotation under normal circumstances is not related to the Coriolis effect or to the rotation of the Earth, and no consistent difference in rotation direction between in the Northern and Southern Hemispheres can be observed. The formation of a vortex over the plug hole may be explained by the conservation of angular momentum: The radius of rotation decreases as water approaches the plug hole, so the rate of rotation increases, for the same reason that an ice skater's rate of spin increases as they pull their arms in. Any rotation around the plug hole that is initially present accelerates as water moves inward.
The Coriolis force still impacts the direction of the flow of water, but only minutely. Only if the water is so still that the effective rotation rate of the Earth is faster than that of the water relative to its container, and if externally applied torques (such as might be caused by flow over an uneven bottom surface) are small enough, the Coriolis effect may indeed determine the direction of the vortex. Without such careful preparation, the Coriolis effect is likely to be much smaller than various other influences on drain direction such as any residual rotation of the water and the geometry of the container. Despite this, the idea that toilets and bathtubs drain differently in the Northern and Southern Hemispheres has been popularized by several television programs and films, including Escape Plan, Wedding Crashers, The Simpsons episode "Bart vs. Australia", Pole to Pole,and The X-Files episode "Die Hand Die Verletzt". Several science broadcasts and publications, including at least one college-level physics textbook, have also stated this.
In 1908, the Austrian physicist Ottokar Tumlirz described careful and effective experiments that demonstrated the effect of the rotation of the Earth on the outflow of water through a central aperture. The subject was later popularized in a famous 1962 article in the journal Nature, which described an experiment in which all other forces to the system were removed by filling a 6 ft (1.8 m) tank with 300 U.S. gal (1,100 L) of water and allowing it to settle for 24 hours (to allow any movement due to filling the tank to die away), in a room where the temperature had stabilized. The drain plug was then very slowly removed, and tiny pieces of floating wood were used to observe rotation. During the first 12 to 15 minutes, no rotation was observed. Then, a vortex appeared and consistently began to rotate in an anticlockwise direction (the experiment was performed in Boston, Massachusetts, in the Northern Hemisphere). This was repeated and the results averaged to make sure the effect was real. The report noted that the vortex rotated, "about 30,000 times faster than the effective rotation of the Earth in 42° North (the experiment's location)". This shows that the small initial rotation due to the Earth is amplified by gravitational draining and conservation of angular momentum to become a rapid vortex and may be observed under carefully controlled laboratory conditions.
So basically you just said it doesn't spin in a different direction and the you said it does, this is probably the most useless bunch of words ive ever read.
Whatch vertasiums video
Nigga wrote a whole paragraph
Why put misleading video here... It's bad to the world :(
These scamsters did not even do their homework and got their directions the wrong way round - it should be clockwise in the southern hemisphere! Easy to accomplish by the way you pour the water!
It’s wrong. In an absolute perfect set up, water will drain counter/anti-clockwise in the northern hemisphere and clockwise in the southern.
why people question? high pressure weather systems also work the same way.
He puts the fin in the center of the tank after the water settles to impart a small rotation to bias the direction of the flow after he pulls the plug. That's the reason for the fin - it allows him to induce the swirl with just a tiny movement of the fin such that it would be difficult for you to perceive it.
the other guy said it's how the bowls are shaped and since I didnt see any movement that would push water in any way, I think it was that
@@wscamel226 I saw the fin move... the water moves with the fluid. Water can settle and be still regardless of the shape of the bowl. Something needs to begin moving the water for it to move in that way
There must be a problem with the surface of the inside of the bowl because in the north it should turn counter clockwise.
the problem is that this is not scientific, because they are using three different pots. It has to be done with the same pot.
It's the same pot, it just has different design. I saw many videos of these and people seem to not get satisfied whether they use the same pot or not. idk why
by same pot we mean use 1 pot instead of 3 separate pots.
I have seen it done by the same pot before, but I agree that it would be better to use always the same pot, but it doesn't change the outcome at all.
Coriolis force isn't strong enough to produce the effect in this video.
ua-cam.com/video/aDorTBEhEtk/v-deo.html
@@TheTruthHz Those guys weren't right on the border of the equator where the coriolis effect is the strongest. And a massive pool with a tiny hole in the bottom will not give the same result as a curved bowl. Think before you claim something is fake.
Ummm, the 0 degree latitude pot has a flat bottom! Use the same pot for all three. Not 3 different pots.
o dear. Do you really think walking a few meters in any direction would make such a difference ? I laugh at this
What caused it then in your opinion?
Watch this
ua-cam.com/video/4IIVfoDuVIw/v-deo.html
I laugh at your ignorance. Educate yourself and things will be become much clearer.
All the information on the internet says that the Coriolis effect occurs primarily in the atmosphere and then only in correspondingly large cloud structures. It has too little effect on water and it is a coincidence, like the swirl spinning in a bathtub or kitchen sink. But there are videos online where a light, square metal kitchen sink is carried on a light frame a few meters to the sides of the equator and the effect is supposedly shown. I believe the statements of scientists who say that the effect on water is far too small and certainly doesn't work that close to the equator. But I can't see anything in all of these videos, which some claim is that the experimenter is naming something with a small hand movement. For a while I believed that the drain pipe in these bowls had a twist in it that forced the water in the desired direction. However, in the videos with the portable sink there is no elongated drain and the sink is rectangular. If it's a trick, and I assume it is, it's well done.
Mark Robber just did a video on it with those square sinks. When there's still a small amount of water in the bucket, the turn the bucket every so slightly so the water pushes in the direction they want it to go. Notice in the square sinks they don't wait for the water to become still before pulling the plug,
Interesting and great demonstration.
What happens if you pee from one side to the other?
Still don't understand how spin in either hemisphere, even near the poles, can be so fast when Earth is only spinning at 15 degrees an hour. Shouldn't be able to notice any spin at all?
You're right: It is too weak unless you're very careful. For reference, Foucault's pendulum erected at the Pantheon in Paris took almost *32 hours* to make one full revolution.
@Hasan M is right. According to coriolis force, the water should spin counterclockwise in northen hemisphere, and vice-versa
Amazing!!!
So 0” Latitude, swallows the flower 🌸
awesome video
Seems to drain much faster at 0* Latitude.
I wonder, if the energy that causes it to spin clockwise in the northern hemisphere, and the energy that spins it counter-clockwise in the Southern Hemisphere, could somehow be harnessed.
Since the force has been pushing this to be the way it is for as long as we know, couldn’t it be put to good use at least?
Briliant observation : ) But also kind of wrong :( The force that keeps the water from draining is the centrifugal force. As the water drains it starts spining - because of this spin it pushes away from the center, so there is less water in the center and so less water comes down the hole. And the centrifugal force comes from water's inertia - so this isn't actually a force. Yes we call it a force, but actually it is NOT a force - that's why I said that your observation was briliant - because you noticed that force, but you were also wrong because you didn't know that this actually wasn't a force. Also to give you some kind of analogy, imagine that in these bowls with holes in the middle instead of water you drop a tiny marble from it's edge. If the marble goes straight towards the center it's gonna fall into the hole imidiatly. Howerver, if you push it in the clockwise direction as it falls it wont fall down the hole imidiatly because it's gonna miss the center and it might even miss it again on it's way back, and again and again and again until it's spinning radius is basically zero so it can finally fall down the hole. The water does the same thing. If it just flows it's gonna go straight towards the center, but if you give it a little push at the start it's gonna flow down for much longer and keep spinning till it drains out completely. Also I should add important thing that the thing that gives it a little push is a coriolis effect - this force is incredibly small, and apears only if something moves perpendiculary to the equator. This is the force that makes the water spin one way or another on different sides of the equator. This force comes from the fact that earth spins so again - this force comes from inertia so this isn't a real force. And also it is incredibly small which leads me to final thing that I wanna mention: this video is fake. Or rather the setup they shown. The coriolis force is incredibly tiny and it could never be enough to start the water to spin - at least in this setup. However this is possible to be observed so I recomend you to see the video on the channel "vertasium" that shows and explains this perfectly(the video is called "does the water spinn other way in the southern hemisphere?"). In conclusion yes there is a force but it doesn't come from where the water flows and it's not even a real force. If I did not explained something suffitiently enough, ask and I'll try better.
The equator, southern hemisphere and northern hemisphere on one price of land lool
I have a turd stuck in my drain and the water won't spin, now how do i find where i am?
well then you have a drain located directly at 0 degrees latitude
The shape of the containers isn't very regular so this experiment isn't great.
Funny they label the basins. They'll never move one to the other side.
Awwsome 😮
This real, but I do think they have it backwards, north and south.
No actually it spins the correct direction in this video even though it is fake. A downward flow spins clockwise in the Northern H. A hurricane has an upward flow of massive air current towards the center so the flow is inverted and so if you look upward the storm in the North it will be spinning clockwise as well even though we generally look downward to see them as counter-clockwise in the North H.
De ce nu a folosit același vas? De unde știu eu ca acele vase nu au o spirală dedesubt care sa dea sensul de rotație?
this illustration has it backwards, water defiantly goes counter clockwise in the north and clockwise in the south. watch other more scientifically done illustrations in other you tube videos
Flower at end! Fwoomp! 😂
The way he pours it in each forces the direction of the whirlpool.
How, when they use the little half circle to steady the water before letting it flow out of the bottom?
Turns out northern hemisphere changed to southern hemisphere and southern hemisphere changed to northern hemisphere. You know what I mean, he wrote it wrong.
The last flower was upside down..it attempted to twist
I know it just the other way: in nothern hemispere the water rotates counterclockwise - you must have somehow mixed up north and south
First of all. Northern Hemisphere, it should go anti clockwise. Southern Hemispheres clockwise. Without watching the video you already know this is a scam because they even got the basics wrong.
Wow nu ma asteptam sa vad romani in clipul asta=)
Nici eu !
The secret is in the tube under. You make it like a screw in any derection you want..
Earth might be flat as well?
That's interesting
I wouldn't be able to call this a valid test. Sorry.
can i ask why?
and the masses lap it up
its due to white paints circle he made accordingly, pans must be on paint. and surface should be level and clean
Take it up a notch. Watch a storm rotation. In New Zealand here a storm always spins clockwise. In the northern hemisphere they go anti-clockwise.
Flat Earth people be like Whattttt, awesome science Information
I wonder what it would do if you stood in all three spots at the same time and tried to flush. 🤙🏼🤘🏼🎯👌🏼 BLACKHOLE.
As of may 182018 it has changed.in texas now it drains counterclockwise.strange.
How are you living in 182018?
I love your vedio, great
Not possible on Flat Earth
lol this is obviously a prank..these two bowls looks the same, but they are not..they are shaped in a way to produce certain spin..take the same bowl and test it on both sides..what a jerk :))
Awesome!
May I ask where the location of this experiment is?
+繆克多 It's not an experiment. It's a tourist trap. You can find them at any equatorial region manned by uneducated fools taking money from uneducated fools using three types of drains on three different tubs. Or often one tub and a flick of the wrist. The Coriolis effect and gravity as a whole is far, far too weak to exert any notable force on such a small quantity of mass.
BaSH PROMPT
Thank you for your reply. Yes, after watched this video, I try to find the proof of this kind of "experiment".
However, all scientific information about this "experiment", implied this is maybe a "trick", because the initial water condition (microscopic water flow) may be the sole cause to effect the following vortex form.
Anyway, thanks for your reply!
You can actually do this experiment from anywhere in the northern or southern hemispheres. If you fill your sink with water you will be able to see with your own eyes which direction the water is spinning. It will be different depending on which hemisphere you live in.
Romanii nostrii.. sunt peste tot :)))
It's a magic trick, don't be fooled.
WHY
that theory is not accurate i watch another video that showing in southern hemisphere the water drain clockwise... but in this video the water drained counterclockwise in southern hemisphere here is the link ua-cam.com/video/ihv4f7VMeJw/v-deo.html
That's fake but true in theory.
Wow
Scam
Northern should be having counter clockwise
Northern and southern locations are too close to the equator to notice any legit direction of spin change IMHO.
You are wrong.

No one else noticed the flower starting at spin clockwise as it was almost finished on the 3rd one?! 😅
Fake and deception.
care to prove that?
You are simply looking at the top or the bottom of the vortex. You have no choice. It is the same vortex. A low pressure vortex cannot change direction of rotation. It rotates in the same direction of spin as that of the planet, that is west to east. Just as the Earth appears to spin counter clockwise in the northern hemisphere and clockwise in the southern hemisphere. Clearly that is not possible as the Earth would be torn in two. Viewpoint has misled us to believe that low and high pressure systems rotate in different directions in the Northern and Southern Hemispheres of Earth and other planetary, stellar and galactic bodies. The discussion in my google book shows that low pressure systems on Earth rotate in the same direction as the solid body, the planet, while high pressure systems rotate opposite to the planet’s direction of rotation, no matter what hemisphere you are in. Turn a model of the world, a globe, on its side and spin it and view it from the north and south pole and then you will understand that vortices just like the planet, spin only in one direction. When vortices cross the equator, they do not change direction of rotation. They do not have to. We are then simply looking at the vortex on its side. We are not seeing that vortex in plan view.The rotation at the equator is up in the west of your position and down to the east, the same direction as the spin of the Earth. Chris Landau.

Romani peste tot ! ! !
It’s backwards lol
My teacher told us to watch *this video*
😳😳😳😳😳
Let's see,---the water is spinning in the wrong direction (he mixed up the hemispheres)---the coriolis effect is at it's weakest at the equator, and no tornado or hurricanes can form within 5 degrees of the equator on a map (meaning even if the coriolis effect determined the direction of the water, they would all go straight down here)---and I live in the northern hemisphere where the water is suppose to spin COUNTER CLOCKWISE, yet my toilet flushes clockwise. You don't need to understand how the coriolis effect works to know how fake this is. The coriolis effect is too weak to direct such small amounts of water. Other things are more powerful such as the weight of the water, gravity, and how the bowl is designed to turn the water. Toilet bowls can't flush straight down or else the water would splash back up, so the water comes out at an angle. Whichever direction it begins with is what it will continue to go, it's not like it'll stop mid-point and go the other way because of the coriolis effect. Same thing with this guy's bowls; he's got them rigged to spin in a certain direction. In this case, the wrong direction!
I say BS! He has simply used three different sink/drains to demonstrate the coriolis affect. This can easily be rigged. It`s just a tourist trap to make money. He collects tips so he isn`t getting rich, just making a living and barely even that.
Steven L Emerson its completely true this is why hurricanes spin away from the equator bcuz of different spin direction
Lol, he looked rich!
Steven L Emerson , try to debunk it
Notice he puts the water in from the opposite side in the second one. It would be more interesting if it had spun the same way...
Bwhahahahah!
Impossible on flattardia. ..
my prof says this is not real, it is a scam
prof ng
I mean, this thing is a scam for tourists... In fact it doesn’t work like that. But if you say that, they’ll tell you that you’re a flat-Earther... (I’m not)
Gangus Khan It doesn’t have anything to do with that - the Coriolis force isn’t supposed to work on sinks, but you can see it on a larger scale (tornadoes)...
Good tourist trap, but total horseshit lol. Carry the same funnel across the equator. It will spin the same way it always does.
What a joke
