This time, I will review the popular YouTube videos.

These days, even if it's good to watch on YouTube, sometimes people skip it or don't watch it if it's too long.

When you watch Youtube, do you scroll and read the comments first?

To save your busy time, why don't you check out the fun contents, summary, and empathy comments of popular YouTube videos first and watch YouTube?

Summary Comments : [Veritasium] 남반구에서는 물이 반대로 소용돌이칠까?

ap*****:

Moments that both of their voices sync
2:42-2:44 (3... 2.... 1....)
3:57-3:58 (The Coriolis effect is UNSYNC )
5:10-5:15 (When the water approches the drain, it swirls (counter)clockwise.)
5:37-5:40 (and thats the truth about *Toilet Swirl.*)

Ja****:

1:50 why did the American say meter and the Australian say feet

Ob*****:

1:04 I'm freaking out about how casual he is being so close to a toilet and touching it.

Jm*****:

2:06 "anti-clockwise"

Po**********:

4:03 reminded me of international air travel companies talking in their language but then talks in english

Pe*******:

At the time I hadn't noticed that Destin, living in an imperial country, used metric units and Derek, living in a metric country, used imperial units.

Da************:

Cue the flat earthers!

YE*****:

When it takes you 5 whole minutes to realize this was a reupload

no*************:

This idea is so weird to me, because every toilet I've used doesn't swirl in any particular reason. The water just kinda goes everywhere.

Wo**********:

still one of my all time favorite colabs!

Al*****:

Once again, we've learned something, thanks to the Simpsons.

Ku****:

OHH... So thats why in tropic, the water is flying up.





Now I know

ma*********:

Never thought I would watch a video of a man staring at his toilet water swirl down the drain.

Fu*******:

Birds fly upside down in the southern hemisphere.

Bu*********:

It's all a matter of perspective. One spins one way, the other spins opposite. Or does it?? Technically, they are spinning the same way relative to each other.

Make a fist with your right hand, with your pointer finger, and point to the floor. Spin it to the right and you have clockwise. Now carefully turn your hand over so it points to the ceiling, and keep spinning. Is it going anti-clockwise? Turn it over again. Now it's clockwise, yet it's still spinning the same direction.....

Bl*******:

Hurricane - north
Cyclone - south
Typhoon - equator

So****************:

Hello mates, I came here to learn about myself :V

AT****:

If you try to flush water inbetween the hemispheres it starts floating and attacking people

Ke**********:

My dairy queen ice creem swirled the same way in US and australia though.

Ch********:

Respectfully, you haven't eliminated all variables. A slight angle of the drain, thermal differences from sun/shade, slight tilt to the pool, manufacturing differences in the pool all could affect outcome. This body of water is too small to be affected. Hurricanes are subjected to very fast upper air winds that get the momentum started---not merely the earth's spin effect on the water. I think you'd have to build 100 pools and conduct the experiment 100 times to actually verify a real statistical difference beyond chance.

I am a huge fan so please don't think this comment critical.

Co****:

How does water swirl at the equator?

Za******:

Hey can I copy your homework?

Sure, just change it a little so no one notices.

Da*********:

The effect is real and is called the "Coriolis Effect" after Gaspard-Gustave de Coriolis (1792 – 1843). The magnitude of the effect increases the further north or south of the equator one goes.

Al*****:

Mind Blown

Mr******:

Are the videos of the pools your only attempts? I would not state that a myth is confirmed with only one attempt on each emysphere

Jo*************:

LIked the way they have presented it without unecessary B.S.

Pa***********:

veritasium, I have a question that none of my teachers have been able to answer.

We know that photons are the particles responsible for the electromagnetic interactions and that they have no mass.
So what is it exactly that we feel when we hold two magnets with the same pole near to each other? What's exactly happening between these magnets?
I would love it if you made a video about it!
-thank you

Qw***********:

Interesting that Destin, the American, said “1.5 meter pool”
and Derek, the Canadian/Australian/American said “5 foot pool”

MI***:

Great now I can correctly guess which hemisphere I'm in in case in kidnapped or become lost

Ra******:

aah, I remembered this, it was hard to watch this with my laptop and phone at the same time XD

Aa********:

By far my favorite collaboration on YouTube ever.

Co**:

The drain is what matters, if you have 2 drains connected, which ever way the drain goes (to the right, it will swirl clockwise) and vise versa.

Mu*******:

Long story short, you could've just looked at hurricanes from both hemispheres to see the if there was a difference

Jo**********:

Oh, I've already seen this video, lol, don't know why this wasn't released earlier, either way it's cool! :D

Go*****************************************:

this must be the world's first double synced repost

tr********:

I remember this and it is still, to this day, one of the coolest things I have ever seen on youtube when I synced the two videos and had one full screen on each of my dual monitors.

On******:

But did you consider angle of attack, perspective, and relative density disequilibrium?


Didn't think so.

bi*******:

Here's an interesting follow-up to your investigations. I've been a hair stylist for 30years in the northern hemisphere. Now on to the good stuff. Hair rarely grows straight out of the body, in other words not at 90° from the skin. It grows out on slight various angles. When many hairs grow in the same angle in an area they are referred to as a growth pattern. Some growth patterns have names such as a "cow-lick" or "whirl"... Men have a much higher occurrence of whirls. Generally they are located in the center top portion of the head referred to as the crown. Whirls are also usually found on the pectoral muscles of a mans chest. I have several clients that where native Australians. All of them have whirls on their crowns that grow the opposite direction compared to those native to the northern hemisphere. Strange since as a fetus our bodies mover around so the orientation would change given the direction it would be facing; yet, this does occur. More to come on the chest hair...

Gr********:

I appreciate the effort you have gone to to undertake this experiment, however, for this to be scientific, it must be repeatable. One single result doesn't prove the existence of the Coriolis effect on this scale. It could have simply been a coincidence. There are factors which could affect the direction of drain rotation more than the Coriolis effect in day-to-day life. It's like the butterfly effect, tiny influences in the initial conditions can change the results dramatically. The wind direction, convection caused by sunlight etc. Possible improvements: Covering the pools with perspex and a cut a hole in the top to let the air in. Put the pool under a gazebo to shade from all sources of light. I would be interested to see a follow-up video of the experiment repeated several times.

Vi**************:

I served a mission for my church in Brazil. One of the first things I tried, was fill a sink with water, let it sit over night, then pulled the drain plug with a string, rather than reaching in. It indeed swirled clockwise. I tried it several times with a sink behind the house, that is normally used for washing cloths. It too drained clockwise. The toilets were no indicator, since the offset jets determined the direction of the vortex when flushed. I was in Minas Gerais, which is far enough south, to make it pretty reliable as long as the water had time to completely stagnate. I even placed a board over the outside sink, to make sure no wind could disturb the water. If you drained the sink immediately after use, any turbulence in the water would override the effect, and it would swirl in either direction, It didn't take much, to influence it.
