    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 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 (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.

    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!

    OK .... I have been in Brazil and New Zealand and the first thing I tried was flushing the toilets. BOTH flushed clockwise, As far as "science" Degrasse Tyson claims this clock/counter flushing is a myth and it all depends on the design of the toilet.
    I SAW IT , Degrasse Tyson confirms it.

    Say nh is left side of a road and sh is right side of a single road. The sun and moon move in the middle in one direction. The sun or moon or both are pulling the water in the same direction causing opposite swirl. Theres ur alternate reason. A youtube user posted a video showing a cue ball always leaning to one side in relation to n/s positioning of the pool table. Says its the coriolis effect. I asked him to replicate in more than one setup. Guess what....video removed. Subject Was about nimrod giants strangely.

    amazing video's and its just proof about the toroidal waves and magnetism being a fundamental key of life. Its weird that i see so many similarities between this shape and lots of things in life like religion but also why we have stronger connections with random people then others... because we all are a toroidal is some form and some stronger then others.

    SmarterEveryDay: I don't see how you can, logically or reasonablly, maintain a swirling Coriolis Effect on a globe where the overall atmosphere is not even independent of the landsphere in it's midst. Afterall, globalists MUST maintain that both the landsphere & atmosphere are moving at the exact same speed. If the atmosphere were not moving, at all, then the landsphere would cause anybody, who is standing on it's surface, to experience as much wind resistance as the speed-of-spin is at his or her geological location. If standing at the Equator, then about a 1,000mph of wind resistance would be generated as the landsphere moved you against the still air in the atmosphere. It would be like trying to stand on the wing of a futuristic jet that can travel at the speed of 1,000mph. This is why globalists MUST maintain that both the atmosphere & landsphere move together at the same rate of speed. If there was even the slightest difference, between the two, then stillness of air could NEVER be experienced on a globe and the swirling Coriolis would have a cause and ever be in effect because of it. However, stillness of air is QUITE OFTEN experienced all over the world. It doesn't even matter if the Equator is moving faster than, per se, the Tropics (Cancer & Capricorn) because the amount of land to speed-of-spin ratio, experienced at every line of latitude, in the whole landsphere, is equal in proportion to every other part. It has to be because it is connected, thereby, allowing no excess force to be experienced (from the overall unit thereof) when transitioning between differing speeds in differing geological locations. The same would, alikewise, be true for the overall atmosphere. Since the amount of air to speed-of-spin ratio, experienced at every line of latitude, in the whole airsphere is equal in proportion to every other part. It has to be because it is connected, thereby, allowing no excess force to be experienced (from the overall unit thereof) when transitioning between differing speeds in differing aerospace locations. And since so called: "outerspace" consists of no substance, at all, then the atmosphere would receive no frictional resistance on it's convexed outer rim from that. Nonetheless, it's concave underside, being a thick gaseous air fluid, would interlock with the landsphere's round ridgity surface (like a bike chain on a sprocket) and, therefore, would allow no kind of swirling motion (or Coriolis Effect) to be experienced (from the overall conjoined unit thereof) when transitioning between differing speeds in differing landsphere-to-atmosphere connected locations. This is because they are married & interlocked as a conjoined unit themselves. Though one is harder than the other, they are conjoined & propelled together at the exact same speed. Such would allow for isolated disturbances (due to other factors) but never as a direct cause of their overall union. This leaves the swirling Coriolis Effect with no CAUSE! So in order for you to continue maintaining the false notion, you will have to dream of a slightly offset atmosphere-to-landsphere connection by which absolute stillness of air is never experienced on the face of the whole globe (even though, in reality, stillness of air is often experienced all over the world in many different locations). Nonetheless, you absolutely can NOT have it both ways, Sir!!! And finally, here is a video of two whirlpools draining side-by-side but in opposite directions to one another --- ruclip.com/video/oebaU1d7wKM/видео.html --- Furthermore, the world's record sniper shooter mentions many variables but the Coriolis Effect is not one of them --- ruclip.com/video/9fiPqUN-AH4/видео.html --- Please don't let your pride cause you to give a dishonest response, Sir.
