13 countries in the world have the privilege to have the Equator line in their "backyard". Have you visited an any of them? Have you seen this demonstration live?
That's curious
Thanks for sharing
It's not just about this. It's about everything. Sure, internet is great and has a lot of information, but a lot of it is not accurate for the very same reason. People hear something and share it around
If you want to verify the coriolis effect with water properly, you should have a container that is round. Any non circular container will induce precession in the rotating water and cause it to rotate erratically. Please do this first before you claim that the events are rigged or fake. For large masses of air or water, when they converge, it will be counter clockwise in Northern hemisphere and clockwise in Southern hemisphere. For small volumes of water or any particles, they will rotate as demonstrated in the video. By the way, coriolis effect is caused by gravity.
@I C Flatwater You will learn the truth, God willing. Thank you for your prompt response.
Crossing my fingers for you 🙂
Seems hard to believe that only a few feet of difference from the 0 equator line would cause the Coriolis effect
its not true
It is hard to believe, because it is clearly trickery and showmanship. :)
It's a scam.
Fake comments too lmfao
🤔 wonder what the benefit of a 'scam' would be in this instance. They get paid no matter what, they host a tourist site. Like a casino.
He's right that the Coriolis effect is stronger with distance from the equator. At this distance it's basically zero. (For those interested, that's because small movements north or south from the equator doesn't change the distance from the earth's rotation axis.) Even at the poles it's a tiny effect on this scale. I admire the smooth hucksterism, though
The movement of an object does not have to change the distance from the Earth's axis to have this object experience a Coriolis force. The Coriolis force is independent of the location of the object and merely depends an the rotational speed of the system (the Earth) and the velocity of the object.
@@miloszforman6270 This is an interesting point! The force is independent of the location, but it relies on the product of the frame's/Earth's angular velocity with the object's velocity *in the plane perpendicular to the rotation axis*. If constrained to move on the surface of the earth or parallel to it, the relevant motion is in the intersection of the plane perpendicular to the Earth's axis (i.e. constant latitude) with the plane parallel to Earth's surface where you are. If you are at the equator, those two planes are perpendicular and the only relevant way to generate a Coriolis force is moving along the equator, which generates a purely vertical Coriolis force: not typically what we think of. But if at a higher latitude, the earth-tangent plane is tilted and movements north and south generate a non-zero horizontal component of Coriolis force. So you're right, but the horizontal C force we're usually thinking of requires movements that change distance from the Earth's axis, and these are only possible away from the equator if you can't fly.
@@agbuckley
_"But if at a higher latitude, the earth-tangent plane is tilted and movements north and south generate a non-zero horizontal component of Coriolis force."_
Movements east and west now also have a horizontal component, as opposed to the equator.
@@miloszforman6270 Oh yes, good point. So yes, the Coriolis force in general doesn't require change of axial distance, but specifically at the equator (cf. the video) that's both the motion required to generate a horizontal force, and the motion not available while stuck to the surface. I didn't phrase that very well, thanks for catching.
INDEED
The Coriolis Effect is very small at the equator, is gets greater toward the poles. This is absolutely showmanship.
But you see here with your eyes the differences ! So even it's small it makes rotate water right on northern hemisphere and left on southern
So they are lying, ok got it
It's a HOAX.

For those curious, you CAN actually see the coriolis effect on water, but you have to have a HUGE basin of water and lots of controls for things like the drain spout and currents in the water. People have done experiments to demonstrate it. But this ain't it.
Smarter Every Day proved it with a kiddie pool.
Yes. This one is just due to initial movement of the water by the way he poured the water (left side, right side, or center). Placing the separator thing for a few seconds won’t eliminate it completely.
Excuses, excuses.
I observe the coriolis effect every time I flush the toilet and watch my dump spin around before disappearing into the abyss
@@Danuxsythat’s not Coriolis effect it’s simply the direction of the flush which is designed by us. Coriolis effect occurs mainly at large scales because parts away from the equator move at a slower speed (because they need of cover a smaller distance at the same time) than parts near the equator. This causes air and water to twirl around due to the speed difference. That means there should be a significant amount of water or air to see this effect because there should be a significant difference in the speed of the earth moving under it.
In order for the Coriolis effect to have significant influence on the flow
of water you need huge scales, like oceans or hurricanes. In small scales we experience everyday like the one in the video the terms of friction caused by the shape of the bowl are the leading terms in the Navier Stokes equation. As scales grow, so does the effect of the Coriolis compared to the previous terms.
BS
@@carlorobotti5572 Key Takeaways: Coriolis Effect
• The Coriolis effect occurs when an object traveling in a straight path is viewed from a moving frame of reference. The moving frame of reference causes the object to appear as if it is traveling along a curved path.
• The Coriolis effect becomes *more extreme* as you move *_further away_* from the equator toward the poles.
• Wind and ocean currents are strongly affected by the Coriolis effect.
@@dillis2188 Do you have a physics, math or engineering degree? Could You explain the Coriolis formula? How much is "strongly" affected? Much on water or on air? (Too meany people are blablablaing without tech knowledge)
@@carlorobotti5572do you? And could you explain it?
I have a degree in engineering from Politecnico of Milan in '80 years, the Coriolis acceleration formula is the VECTORIAL PRODUCT (I dont explain what operator is x) Fc= - 2 omega x V where: 'omega' is the earth rotation speed vector and V is the velocity vector of the point/object subject to the acceleration.
Does't matter how big or large is the system affected. It influence water in any sink hose where the velocity of the water is toward the ground or create hurricane when cold or hot air is moving up or down, normally up when it is heated by the ocean and sun.
Clear?
Misinformation is an industry for people control
same "tourist traps" exist in Peru, Brazil... anywhere you have tourists with very little physics knowledge. With enough dexterity, you too can reproduce these three behaviors (flower turning on itself clockwise, counterclockwise and not turning) with a similar equipment from where you are, no matter how far from the equator.
Have you tried replicating it?
That's a very slick piece of con-artistry. He is to be congratulated.
Not everyone will be fooled, of course
What he did is self-explanatory if you understand the Coriolis effect?
Fill up your sink with water. When you pull the drain to empty it, watch which way the water spins. it will not go the other way by itself!
If you are south of the Equator, it will go in One Direction.
If you are north of the equator, it will go in the opposite direction.
Apparently if you're on zero latitude it will drop straight down without Spinning!👍
@@ronniepirtlejr2606 The coriolis effect is absolutely miniscule at this scale and is completely dwarfed by the tiniest amount of initial angular momentum in the water. The effect is even smaller when you are close to the equator when small changes in surface position create a tiny change in radius of the frame's motion.
I don't think I'd be exaggerating to say a bee could fart a kilometre away and change the direction more than the coriolis effect.
The bowls are just profiled a little differently. If you swapped their positions around their contents would all still rotate in the same way.
Of course he has his setup backwards, the coriolis effect causes the opposite effect to what he is "showing" here. It's actually an absolute proof that the coriolis effect is negligible in the situation, since coriolis would cause counterclockwise rotation in the northern hemisphere and clockwise in the southern, and his bowls are obviously overcoming this consistently.
@@rageagainstthehygiene2357 you don't think, you imagine. Try thinking. It's addictive. Once you start, you can't stop.
@@thehellyousay 🤨
@rageagainstthehygiene2357
Great catch on the wrong directions. I've seen the same scam in Ecuador, but at least they did it the right way.
Nice demonstration, but you won't see a Coriolis effect in such a small scale. Look for cloud formations on satelite maps.
At the first one he pours the water more on (his right) side of the hole. The next more to his left. The last one straight in the middle. He does not leave the "rotation stopper" (a red herring) in the water long enough to totally stop that slight rotation he created. I'd say pour in the water in all three, wait 5 minutes and see what happens. Put the flower in before unstopping the hole. He won't because the demonstration would not work or be obvious. It's fine for funnsies, but not scientific. I've seen people do it by doing the same thing no where near the equator. Debunking this specific "effect".
Very well done. I am happy to see people that have woke up and who are seeing the lies before us.
@@kennyhogg5820people are so easily duped.
What about your toilet? Also, high pressure systems go one way and low pressure go the other.
@@SongMom8 The holes around and under the rim of a toilet are angled to cause the water to swirl one direction or the other. It will always swirl the same direction no matter if that toilet is in the Northern or southern hemisphere. Look closely under the rim when flushed, you will see the water jets are angled.
The trick is that the direction of rotation depends on the initial position he throws the water. He pretends to stabilize the water but there's still some inertia. First he throws the water with the bucket slightly to the left, the second time is slightly to the right and third time is in the center. You can do it at home.
Yes, you got the right answer. Just another way to take some easy money from fools.
Wow that is really interesting. Learn something new every day! Thank you Kalungi!
Not only is the coriolis effect negligible at those distances, but he got the spin direction wrong. Its counter clockwise in the North and Clockwise in the south. Bonus: it only works for large systems such as hurricanes not your kitchen sink

He forgot to swap the containers to prove they spin in one direction only because of the hemisphere and not the shape of the container.
th-cam.com/video/mXaad0rsV38/w-d-xo.html
Ya I'm more than a little skeptical. I'm from Canada so we have a very strong coriolis effect, and even so, we can force it to go the wrong way depending on how you pour the water or the shape of the container, so on the equate it definitely wouldn't be as reliable as he's showing here with just 10m difference. I call BS: there's a trick involved.
The containers are labeled backwards 😮 should be counter clockwise in the northern hemisphere
It is in Uganda…that is on equator….so this is just a demonstration trying to show Coriolis effect.
In general the effect should not kick up if the experiment set up is not relatively large…Remember the movie Escape plan….commode flush seen…that just do not happen in reality!
In this demonstration…except the equator demo rests of the containers are designed to flow the water in respective direction.
@@parikshitde3147Uganda is in equator
The directions of rotation demonstrated in this video are NOT due to the Coriolis effect for (at least) 3 reasons:
1. The Coriolis effect is too small to have a noticeable influence this close to the equator.
2. The size of the bowls is too small for the Coriolis effect to have a noticeable influence.
3. If the Coriolis effect is really causing the direction of rotation in this situation, the rotation would be in the opposite directions than shown. (Low pressure systems rotate clockwise in the southern hemisphere, and counterclockwise in the northern hemisphere. The water funneling towards a central point in the bowls is analogous to a low pressure system).
It shows the field shoots out the north and south pole and come in at the equator. Great experiment
Great proof of how the coriolis effect drains your wallet effectively in the undesired direction 😂😂
that's not the Coriolis Effect draining your wallet...that's the US Government Effect doing that
Explain how you came to this conclusion, please.
Phaha
@@timhallas4275satire is a virtue
@@timhallas4275
They charge tourists to demonstrate this.
I hope you learned their language for "We scammed some more tourists!"
The Coriolis effect isn't strong enough to have any effect on such a small body of water. Even if they were huge bodies of water, they're all too close to the equator. If you look closely, he slightly span each flower in the direction he claimed the water was rotating, but there was no light reflection of the water doing the same thing. It's all done with slight of hand, just like street card tricks.
I agree that this is a scam. The effect is too small so close to the equator and with such a small body of water. That being said, I would gladly pay to watch it if I were to go there. His showmanship was great.
The water seems to be moving with the flower. I think he's creating the effect, but with the bowl and not by spinning the flower.
Yeah, the water is obviously flowing with rotation, probably something to do with the exit orifice
The surface tension in the water is too high to allow the flower to freely spin like that
It might have something to do with either the exit orifice or with the way he lifts the divider
If you watch the first pan closely, you would see there are deformations at the base of the pan influencing directional flow. I'd inspect those pans properly for those ridges they put at the bottom of the pan
ALWAYS WONDERED about this. Thanks
You also wonder how a magician cuts a woman in half too don't you?
The best thing is that he is applying the phenomenon of large area with such a small apparatus. It seems that result is not correct because macroscopic phenomenon usually don’t apply to microscopic phenomenon. If you have doubt then take a container and make a hole at the bottom, it doesn’t necessarily whirl the flower in only one direction.😊😊
This destroys the flat earth followers wet dreams
Water goes down the drain anyway it wants. The coriolis effect only works on large systems.
It does? What?? Lol
I'm afraid not. I've seen better card tricks.
20 foot either way ? Not sure about this one.
They are still holding on to the theory like they really are going to fly off of the planet.
Just few metres and such difference? Imagine force in Canada for example. That flower would spin so fast that it would create giant black hole! 😂
Exactly! That's called Darth Canadanus effect!
This is a trick
Isn't that because Canada is close to the North Pole?
No. Just the same pace.
I dont think you understand the science of a black hole
For those woundering he just waits till the waters starts doing the spiral for the two first and the last one he puts the flower as soon as the water starts going and by keeping it at the middle it stops air reaching the hole. You can also do this in your sink it you wanna try.
I live 12 miles from the Equator. They do the same trick down here in Ecuador. I am guessing Uganda's Equator moves as ours does with each earthquake. So it also works within a few miles of the Equator too. But it is a good trick. When people want to visit the Equator I tell them to bring a GPS and then visit the Middle of the Earth Park.
The direction of rotation depends on the shape of the water outlet, just a small deviation is enough and the water is spinning, just like water creates a vortex in the drain of our bathtub.
yea, i have different directions in two sinks that are right next to each other 🫠 and a friend claimed it always spins same direction....h was shocked after one quick demonstration lol

@@krisg822 sure you do.
Okay so what's the explanation for the water not spinning at all at the 0 line
There is not enough time for the Coriolis effect to influence the direction of flow in the water. The shape of the bowl or the way the water is poured dominates the direction of flow, with the affect of Earth's rotation minimal, especially considering it is at the equator where the Coriolis effect is almost zero (it is maximized at the poles).
I would agree on that if not the "no vortrtex" plate. HowTF can you shape that?!!
You have right.
@@dani-il a bigger hole and straight guides in it may do the trick. I also feel this effect, while real, would not be so apparent or quick that close to the equator.
@@patrickbullock2136
This effects is explained by difference in radius on different latitude.
Veritasium chanel have explained this and confirmed scientifically. 😉
Who are you to question his wisdom
This is so awesome. Thanks for sharing :D
Fun fact. On north side coriolis effect should spin vortex couter clockwise and clockwise on south side. This "experiment" is a poorly executed trick. Thanks.
Угандийские кориолисовцы такие суровые, что им нужны три разных стенда для демонстрации эффекта :). Что-то мне подсказывает, что все эти три установки работают одинаково в любой точке земли. Они и на северном полюсе будут по разному крутить воду :))))
We visited the equator line right outside of Quito Ecuador and they had this same demonstration setup. They actually wanted u to give them money to show u this. A few locals told us not to pay for it bc it was a trick.
yes, same principal. The local guy who was with us paid for the demonstration.
Good of the locals to warn you... sounds like a nice place.
Smart locals.
How is it a trick? It’s fact. So why not give the local a small tip? Have to make a buck somehow, can’t discredit them for being entrepreneurial.
@@TripReviews.. It's a scam the bottom of the bowls the strews are all different to make the water spin ... 😂 ...
Interesting demonstration, but I’m skeptical that the observed rotation of the draining basin water was actually caused by the Coriolis effect linked to the Earth’s rotation on its axis. Coriolis induced rotation is a real physical phenomenon and the effect can be observed in nature. For example, in the northern hemisphere Coriolis deflection causes large storms, such as hurricanes, to rotate in a counterclockwise direction, while in the southern hemisphere the same weather patterns rotate clockwise. In the experiment shown in the video I’m wondering if other, stronger influences were at play. The basins used appeared to be made of concrete and were roughly shaped. It’s more likely the unique shape of each basin had a dominant influence on the direction the water drained. There’s a classic popular experiment employing water draining from toilets or sinks located in each hemisphere. If the Coriolis effect was the only consideration water should drain from these plumbing fixtures differently in each hemisphere. I’ve carried out this experiment myself with a friend living in Australia (I’m in the U.S.). We observed the same rotation in both hemispheres, due I believe, to the sameness or very similar designs of the toilets featured in our experiment. The Coriolis effect, especially so close to the equator, should impart only a very tiny force on the draining water. A much larger influence would be the shape of the basins, differences in starting water flow, and possibly other variables too. These considerations, much more so than any effects related to the Earth’s rotation, would likely determine how the water drained.
Love this guy's entrepreneurial spirit, even if he is filling tourist's heads with nonsense :)
I understand the true science but this dude so smooth I’m not even mad 😂
What a shame …. You promote lies
Right? He even appears to steady the water.
@@Professor-taboo's not lies, it's just not accurate. This is an educational demonstration that'll stick with people, and it's -mostly right. I'd be upset if he was teaching it backwards or something, but on the simplest level, the lesson is correct.-
They're literally labeled backwards 😮 : coriolis is counter clockwise in the northern hemisphere
When I was a kid in 8th grade, I did an experiment to show this. But what happened surprised me. I did the experiment over 50 times. I was shooting for 100, but eventually gave up. They water went clockwise some time, and sometimes went counterclockwise. Whichever direction it went just became the way it would go. It would drain the entire tub going one way or the other and never change. I didn’t use a divider to stop the waters movement. Just poured it in and pulled the plug. So whichever the water’s inertia was, it was enough to make it go that way and stay that way. This was in Indiana, nearly to the north pole compared to Uganda. I considered the idea busted. There was more about the pouring of the water than the Coriolis effect.
Wow, thank you, Africa is truly an amazing homeland for all of us. No matter what color you are, if you go back in time far enough, we were from Africa.

Nice video but the Corolios effect doesn't have any impact on the spinning of the flower (This is a small spatial scale)
Thank you for your input :)
True
it does th-cam.com/video/mXaad0rsV38/w-d-xo.html
Exactly, not because of 10m difference. Maybe 100km, but even then I'd expect it to be quite unreliable owing to the movement of the water being poured into the bowl. I wouldn't expect it to be 100% reliable until you're at least 30° north or south, the forces are just too small. Also they're backwards: coriolis is counter clockwise in the northern hemisphere 😮
We need to see the drain's shape or angle of the hole, because if it's shaped like a corkscrew or angled, it'll cause the water to drain in a specific direction (counter/clockwise).
Then do the experiment by yourself
at 16s you can clearly see the bowl has directional perforations at the bottom to guide the water.
You don't need to shape the bowl. Just pour the water into the basin from a different direction. It will take at least 10-15 minutes to settle so the water is no longer even remotely spinning so you just pull the plug before that happens.
@@dubiumguy While something like that would work, it's not as easily and quickly repeatable. Plus you can fuck up, with shaped bowl it works every time.
@@jfarinhote sure, will you send the ticket to Uganda?

Exactly! Spot on! 😃 👍
I observed that after he poured water, the water in the pool in the southern hemisphere had turned counterclockwise, while the water in the pool in the northern hemisphere had turned clockwise. Notice that the small bubbles on the water surface reveal the rotation direction of the water. Although he put a baffle in the pool, it was not enough to eliminate the potential rotation. I also observed that the blocking time of the baffle in the southern or northern hemisphere is 4 seconds, while the blocking time of the baffle on the equator is 14 seconds. The performer used his words to cover up the time gap. This performance is only a way for local people to earn money. Therefore, tourists need not take it seriously.
Ya I noticed the amount of time on the 3rd one too
Also, the coriolis effect on the equator is 0
-Still, the underlying lesson is correct,- even if the demonstration is a sham.
They're backwards: coriolis is counter clockwise in the northern hemisphere 😮

I would say there is not enough of a variation to produce such a drastic difference given how close all the bowls are to the equator. I wonder what the tip was to perform the “demonstration”.
The shape of the Bowls is not perfect, and just a little groove is enough to provoke a whirpool in one or other direction. The central bowl has a thick and accurate thing in the middle, AND a thicker hole, so the whirpool does not get to form - the water gets down quicker.
He sells a certificate for 10,000 Uganda Shillings, which is about $2.66 American or €2.52 or £2.19.
That's probably an "add-on" after some nominal performance/admission fee.
You so wise. You know that?
It is binary. And you can clearly see that the effect is extremely small.
Thank you so much for an intriguing and enlightening experience thank you for all you do it really made my day!
It's a trick though.
I know it's a setup but he is still demonstrating what happens. Neat little demo for anyone visiting the equator I guess.

They should use only 1 bowl that moves to all 3 stations. The grooves in the bowl can easily alter the waters movement

@@asifmetal666 Idiocracy is one of my favorite movies. I've watched it a good 8-10 times. And people that suck this stuff up are the progenitors of the mouth breathing morons of 500 years from now. It's SO clear that the guy pours on opposite sides of the bowl in the different hemispheres to give the water a little spin (other videos show that better). And then on the equator he pours directly in the center and then holds his blade in the water quite a bit longer than the previous 2 times to stop any spin (pretty obvious). The Coriolis effect is very real in weather systems spreading hundreds or thousand of miles, but in a bowl of water it's calculatable but certainly not demonstrable. If you don't understand that then you are dupable too. But I imagine you are one of these people that can never admit you're wrong, so go on and believe the ridiculous.

Corriolis Effect does exist, but a few feet won't make that much of a difference. The nozzle has ridges that makes the water screw in a particular direction when falling.
In southern hemisphere isn't it should be clockwise and in N-hemi anti clockwise?
I tried this many times in my bathroom sink and it usually rotates clockwise but I'm in Illinois it should be counterclockwise,a few times it rotated the other way and once it didn't rotate at all.
@@hifijohn the bathroom isn’t a good way to test it
It is because of the design of the sink that the water moves the other way

Interesting! I guess if you hate the summer you can walk a few feet to the other hemisphere to experience winter (what sucks about being on the equator is it’s always hot no matter the time of year)

It's a trick..... The direction of water outer flow depends on the inner structure of the tube which is connected at the bottom....
Spiral threads (clock wise / anti clock wise) inside the tube can regulate the direction of water flow.... Plain tube doesn't produce any whirl in water.
Oh look, a flat earther
@@Novmik0921 What?? He said nothing about flat earth. It's just that any minor agitation in the water would have had much more of an effect on the the direction of rotation than the Coriolis effect for him to repeat this demonstration reliably, especially if you're only a few meters north or south of the equator.
@@Novmik0921
Why did you call him a flat earther when he just knows how this trick is done? The myth is that in the northern hemisphere the water goes down one water and in the southern it's the opposite direction. This is not scientifically accurate and you can test it for yourself if you travel. It's funny how you insinuate he is ignorant when it is in fact you who is ignorant in this case.
Oh and no I'm not a flat earther in case you also throw that at me.

This is known as a great trick in the art of magic.
That is friggin amazing.
Really cool, Thanks for sharing.
hello I am from Pontianak city, Indonesia, here also has the equator 0 °
Greetings :))
Gak ada yang nanya bro???
@@starrisinga6282 kamu orang Indonesia tak bangga dengan negara kamu? Kesian
Does the average rainfall increased in equatorial region ?
Im living in pontianak too
The coriolis effect makes hurricanes spin counter clockwise in the northern hemisphere and clockwise in the south. Opposite of what he was demonstrating.
That's because he wasn't demonstrating a hurricane.
@@MrAnswerification They are both low pressure in the middle, same thing! Fluid wants to move in, but starts spinning because of the coriolis effect! In high pressure systems the fluid wants to move out, so it spins the oposite!
@@nielsdaemen I've learned 3 things today then: that the Coriolis effect spins hurricanes and water differently, this is due to pressure effects. And that the bloke's water demonstration has a touch of skulduggery.
Could I set up an infinite flow device using the equator and different polarity’s? And generate electricity from it?
How cool! Thank you!!
I can assure you, that it's a trick. The coriolis effect is a very real effect but far to small and insignificant to be determined and demonstrated in such a small experiment. If you knew the mathematical interpretation and have studied fictitious forces in non-inertial frames of reference, you'll know for sure that I'm right.
To performe such an experiment you are only allowed to change one variable at the time. That he chooses to use different funnels at different locations should make you suspicious.
The trick is probably due to different shapes at the inside of the bottom (the pipe) of the funnels.
Furthermore - and that's the worst part - they have made a crucial mistake, and made the funnels with the opposite directon of rotation of what we should expect from the coriolis effect.
He might seem to be a nice guy, but he tricked you.
Let's be honest - he's demonstrable dishonest.
Curious. Thanks for sharing, Erik

i found a video that support your thought.
Just make him use center bowl (with no curves on the drain pipe and that is water goes faster) on all 3 ''experiments'' and he is gone. He just talk to distract you from thinking....you're 100% right...THIS IS FAKE!!
That's because the world is a stage.... it looks so fake it has to be real...
as someone who wasn't there and is only speculating, i call bullshit on you erik. do you want a cookie to make yourself feel better? tell you what chump, and i know it's easy for me to say this or even pose it to you, but it is equally as easy for you to say what you did. Go there. make your own video. make it just the way you just said. be sure to show your work! i wouldn't want any to call demonstrable dishonest.
If you rotate manually the water that can flows out opposite to what you expect. I think the rotation can also depend of the shape, maybe so near the equation depends only for the shape. Will be more interesting If we can see a swap of that two pots. 😊 This is called scientific method. From Galileo.
Muito bom!! Vídeo muito bem feito. Bastante interessante esse efeito na água. Parabéns pelo vídeo! vídeo!! Um grande abraço de um brasileiro!!
its fascinating that the effect is observable so clearly despite only making a few steps
It isn’t. The bowls are engineered to induce a spin.
Thanks for you to shown equator line.
My pleasure :)
This is done in South America also...no need to defame these people because it's a wonderful presentation and if you buy a certificate it's just like the souvenirs that you buy on every port of call. This man is a legitimate business for hire! Great job👏🏾👏🏾👏🏾

Mis-teaching science is hardly a thing to be admired nor respected.

@@AliErbatur-zv2vy its all made up this doesnt work like this.
This is an amazing demo
The Coriolis effect is a real phenomenon that influences large-scale systems like weather patterns and ocean currents due to the Earth's rotation. However, its effect on small-scale experiments, like water draining in sinks or bathtubs, is often overstated or misconstrued.
In the context of a demonstration at the equator, there are debates and misconceptions regarding whether the Coriolis effect can influence the direction of water flow in a basin or sink. In reality, factors such as the design of the basin, local disturbances, and the initial motion of the water have a more significant impact on the direction in which the water drains rather than the Coriolis effect, especially in small-scale experiments.
At the equator, the Coriolis effect is theoretically negligible because it has less influence at or near the equator due to the minimal difference in rotational speed between different latitudes. The effect of the Earth's rotation on small bodies of water, like those in basins or sinks, is often outweighed by other more immediate influences, such as the water's initial motion, the basin's design, or minor local disturbances.
While there might be demonstrations claiming to show the Coriolis effect on water drainage at the equator or in different hemispheres, it's essential to approach such experiments critically. Many factors can affect the direction of water drainage in small-scale experiments, making it challenging to attribute the observed result solely to the Coriolis effect.
For accurate demonstrations of the Coriolis effect, observations are typically made on larger scales, such as the movement of weather systems or ocean currents, where the influence of the Earth's rotation becomes more apparent.

That was very educational. Thank you for taking us along. Sending love and warm greetings from Missouri.
This is fake. A tourist trap that you can find all over the world. The Coriolis effect does exist, but it only affects very large systems. Here, the water could flow in any direction. The shape of the basin has much more of an impact than the Coriolis effect, which is absolutely negligible here
@@ao9779 ...very interesting
@@ao9779it's not really fake, rather it's a demonstration showing how the Coriolis effect is different depending on your hemisphere, it doesn't work at this small of a scale but it's still educational.
@@gu244it would be educational if they explained that the effect is very small on this scale, and admitted that they have tipped the scale to demonstrate it.
As presented it gives a poor misunderstanding of the effect and more or less no explanation of why it happens.
Since they got the directions backwards as well it is actively spreading misinformation. This is not education.
It would be educational if they hadn't confuse rotation direction.😂
amazing what a few steps make a difference.
Nice. It flows way faster on the equator line.
Okay I'm going to study
Me at 3 am: mmm yes, water experiment

I feel your pain 🥲
Hahahhaha
Какой грамотный парень. Я знала про эффект Кореолиса: реки в северном полушарии сильней подмывают правый берег. Но чтоб эффект проявлялся в 10 м от экватора! Не верится.
I KNEW ABOUT THE NORTH SOUTH DIRECTIONS BUT I HAD NEVER THOUGHT ABOUT, AT THE EQUATOR. LEARNED SOMETHING KNEW, THANKS
I had no idea. Learn something new every day
Living in a country that have an island in at the equator line is a blessing and a curse. It's a blessing because we can almost plant every fruit here, we only have two seasons. And the curse is the weather is hot AF sometimes. Plus, I want snow :(
Die you ever saw and experienced snow?
No you don't. I say this as someone who did move from an equator country and was excited to see snow for the first time.
The novelty wears out after a few years.
You dont want no damn snow..trust me...very little people will choose snow over sunshine.. you want to experience it..not be stuck in the house, vehicle getting stuck, acidents dirty snow,slush, salt damages vehicles sun not coming out all day, shoveling snow etc...then imagine getting to an old age hoe much more difficult it makes things..had to hit you with reality kuz africa really might be the best move for black Americans
Trust me you don't want snow. I'm from and in Detroit. LoL trust me bro you don't want the white stuff. Maybe once but not yearly. Winter seasons even affect our metabolism if you are born in a 4 season climate. Come Sept I crave pasta and carbs to fatten up for winter. Come April/May I crave fruit and light meals. Thing is older I get the harder it is to deal with cold. If I was in a warm climate all year long I'd be a much more productive person
One would think so.....
But every time I travel to a warm country where I have friends, they are always out and about.
"Let's go for a coffee"
"Let's grab a beer"
"Let's meet at the beach"
Something is happening at any given moment. I always wonder "when do those people work".
I think the answer here is to find the ideal scenario for everyone. Luckily, we live in times when we can travel (and relocate) freely
It's always awesome to see physical concepts being shown practically
Even if they are faked

I was there in Uganda also way back 2006 up to 2008. 2 years of staying there, Yes people are friendly. I try also their local wine called Waragi.
Thanks for sharing!
How was the wine? Also, what's your favorite thing about Uganda?
Waragi is a Gin
@@teyharDifferent cultures define "wine" differently. In China Beijiu (30-60%abv) is considered "wine".
@@teyharAnd in Canada, anything made without distilling is considered wine, including berry wine, apple wine, and potato wine.
@@wilfdarrUgandan here! Waragi is not wine.
Will they repeat the experiment with the same vessal for the three cases?
No. 10m from the equator is not enough to see this effect without some sort of trickery. I doubt if 100km is enough to get reliable results. My guess is not until your above or below 30°latitude will it be strong enough to see it reliably. This is just a demonstration.
Perfect to watch!😎

I quote an excerpt (translated into English from the Spanish version, so there may be some difference from the original) from John Lloyd and John Mitchinson's book 'The Great Little Book of Ignorance':
The widespread belief that the Coriolis effect, created by the Earth's rotation, causes water to spin as it falls down the drain is not true.
Although it influences long-term weather patterns such as hurricanes and ocean currents, it is too weak to have an effect on domestic pipes. The direction in which water falls down the drains depends on the shape of the toilet, the direction from which it is filled, and the vortices introduced by using the water or removing the plug.
If a perfectly symmetrical container were filled with water, with a tiny drain and a plug that could be removed without moving the water, and left for a week or so, so that the movement stopped completely, in principle it would be possible detect a small Coriolis effect.
