Some notes about this.
We each repeated the experiment 3 times, and got the same results every time. For those of you who might be skeptical, great! The good news is that right circularly prismatic kiddie pools are only $10 and you can do the experiment for yourself at your latitude. There's really no reason you shouldn't do this on your own, so before you criticize how we've done it, I'd strongly encourage you to do it for yourself.

Gordon McGladdery did all of the sound design for the video. We used two songs from other artists (licensed of course). Derek split the first one up so it fades from video to video, and Gordon split the instruments up on the second one. There are violins on one video and percussion on the other for example. It's really neat.

The neat earth animation at the beginning and the synchronizing timer was made by http://eisenfeuer.com/. He also made still images of the earth from the top and the bottom.

Thanks to Jacob Vehrs for helping make the plywood pool platform.

GET SMARTER SECTION:

There was a study performed at MIT years ago (http://web.mit.edu/hml/ncfmf/09VOR.pdf) that explained the physics involved. We repeated some of these demonstrations, but on opposite sides of the globe…and in a way that can be easily understood.
This site is a great resource on the Coriolis effect and ways people have gotten it wrong:

The Coriolis Effect influences the flight of a bullet.

We would love for someone to replicate this demonstration. Please tweet your results to us @SmarterEveryDay and @Veritasium.
Here's the link to puchase the exact same pool:

Tweet ideas to me @SmarterEveryDay

The thought is it will help educate the world as a whole, and one day generate enough revenue to pay for the kids' education. Until then if you appreciate what you've learned in this video and the effort that went in to it, please SHARE THE VIDEO!

What happens if you drain it upside-down

Автор Benjamin Hershey ( назад)
Protip: put Destin on the left and Derek on the right for proper orientation.

Автор ERA ( назад)
its funny now people make big deals about small things like which way the water swirls xD Why does it matter which way it goes down? Just be gratefully that it actually goes down!

notice he put the water in clock wise thats so it would go clock wise this whole water thing is just a wives tail its just a myth its fake

I think you should go to the southern hemisphere and do it again.. that would be proof

Автор Dartnix ( назад)
One of the best ideas I've seen on youtube and very well put together!

Ya'll did great!

When you get the timing right first time and the videos in the right order ... YEAHAHAHAHAA

Hahaha, I have a dual screen setup so synching these was not hard, but I chose to put Veritasium's video on my left screen, which broke the immersion at the end :D

This is one of the best uses I have ever had for my second monitor :)

Автор anonymous bosh ( назад)
This could be faked or it could be coincidence. Either way it's an utterly ridiculous way to try to prove something that is theoretically true but in practice has been shown at least twice by universities with far more resources and patience than you to be impossible to prove or disprove on anywhere close to such a tiny scale. Attempting to do so using loose plastic kiddies pools in any old room is not only laughable but now casts serious doubt on your ability to inform us of anything with any certainty at all. Well done.

Автор Oscar Jeans ( назад)
waiittt.... how does video have 200,000 more views?? but 1000 less likes?...

Автор Evan Tee ( назад)
Watched this with dual monitor one video on each. pretty cool idea

Автор WheatWormStudios ( назад)
Too bad you made a video without doing any research. A toilet isn't big enough to be effected by by your made up effect and that has been documented. It has everything to do with the design of your toilet. Fail

Автор Wynand Henderson ( назад)
Very cool experiment, but I would like you to at least test 3 times at the same place and replacing the nozzle at the bottom.

Автор Bron Cinzah ( назад)
If you understand this video i think you

Автор Seán Mercier ( назад)
Hey guys, wanted to say I've been watching both of your channels for a while now and just stumbled across this. Being from a Video making background, I found this synchronised fusion really exciting on top of your usual high quality content. Thanks for doing what you do!

Автор williamstdog9 ( назад)
Awesome vid(s) bro(s)!

Автор DR. NEO ( назад)
the sync was amazing

Автор littleratblue ( назад)
If all the variables weren't cleared (and, given that one of the kiddie pools was outdoors, I'm finding that unlikely) and the results were random, then with only a single test case, there was still a 25% chance that you would get this result. You would really need to repeat it a few more times to call it science. (Though it is reasonable to think that the end result would prove the Coriolis effect).

Автор Vincent Paul ( назад)
I synchronized the video and it was very interesting.

Автор sranjesuper ( назад)
So u did this experiment in one hemisphere and ONE time to prove this is real? Do this experiment 50 times and if all 50 times the water goes the same way, then you may have proved something. Then change the pool size, and plug size and do it 50 times again. Then you may have proved it 100% You usually post good videos, but this is very very inconclusive

Автор Will Bowie ( назад)
What if this was done on the equator

Автор smoothy hack ( назад)
how about a pool on the equator. no spin?

Автор sir FARTSalot ( назад)
Hey Destin,stin, i have something to say, at work every now and then I have to drain a sump of water and I've drained it onto concrete and then it goes down the concrete drain but when it goes down it goes anti clockwise but I am in Karratha Western Australia can you explain this thanks

Автор KWSNinja ( назад)
Wrong. The Coriolis effect is not nearly strong enough to affect small kiddie pools. If it works on that sort of scale, hurricanes would be going over Mach 5. It depends which way the water is flowing, along with other microscopic interferences.

Автор Death_Kenny ( назад)
Got it timed perfectly first try... Really amazing Idea of you both! Loved it!

Автор Andrew Ivanov ( назад)
This is caused by Coriolis effect. Simple physics. Coriolis effect is responsible for many weather patterns and hurricanes.
Aren't they teaching this in schools? This is Middle school physics.

Автор Maven Sony ( назад)
Now do this experiment in exactly midpoint of equator .Lets see what happens..

Автор znatim ( назад)
You could mention Foucault experiment

Автор CiPoint ( назад)
The result would be much more convincing if you repeated the experimemt e.g. 10 times. Otherwise it can't be considered as a proof.

Автор AsG1989 ( назад)
it doesn't always spin the same direction

Автор Amirnake ( назад)
Ok Destin, since you're vouching for the bearded guy can you explain to us how it is possible for the light of an object traveling away at faster than the speed of light relative to point A to reach point A? Point A relative velocity to object is more than speed of light. I forget his name no disrespect but the bearded guy on his channel said that's possible. I don't think point A will receive any information from the object.

Автор Strike Eagle ( назад)
That... Was... AWSOME! The 2 vid idea was crazy cool!

Автор Ray Grant ( назад)
That was a good explanation of the coriolis effect!

Автор Big Nasty ( назад)
you should have measured the speed of the swirl, i bet it matches the speed of rotation of the earth, relative to its size.

whats happens when on the equator

mine doesnt swirl

i hate your idiot face

Автор Ibakon Ferba ( назад)
This is seriously one (or rather two... 1 1/2? :D) of the most amazing videos on the internet! Just rewatched it and I wonder: what would happen if you would do this experiment exactly on the equator? would the be no swirling at all?

Автор zazke girotron ( назад)
I wanna see what happens in the equator or exactly at the north pole with the same controlled variables, great video both of you

Автор oceanceaser ( назад)
This is AWESOME

Автор MrKockabilly ( назад)
You should have done that round plastic pool experiment at least several times and also do it in southern hemisphere to validate your theory further.

Автор santiago velez saffon ( назад)
This was awesome!!!!

Автор Miteran Official ( назад)
they both rotate in the same direction relative to each other but relative to clock they do not rotate in the same way becouse the experiment is not done in the same coditions relative to winversal directions. In one pole of earth you must see the clock from up and the other pole from downs point of view :P So without correct references no one can say that you are wrong. If you compere the earth rotation from diferent poles you will say that the earth in one pole rotate like clock direction and other pole earth rotate anti clock direction if you see the clock from the same direction relative to gravity.

most impressive video i have EVER watched on Youtube hands Down..Thanks guys for making us smarter every day.

Автор Ventures With Joe ( назад)
Contrary-clockerwise

Автор Rob Gandy ( назад)
Yes, I agree. Nice sync gentlemen. Well done. Plus the Coriolis effect. Two wonderful subjects.

Автор Joe Deglman ( назад)
The rotation in a toilet is caused by the manufacture design of the toilet ejecting the water at an angle. Some toilets gush straight through no rotation. If the coriolis effect could cause enough deflection to cause that rotation in a toilet, you would pee on the person next to you when going at the urinal.
