    Some notes:
    We each repeated the experiment 3 times, and got the same results every time. For those of you who might be skeptical, great! A right circular prismatic kiddie pool is only $10 and you can do the experiment for yourself at your latitude. There's really no reason you shouldn't 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.

    MORE INFO:
    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:

    I understand that the flat earthers don't believe in water, so this experiment won't help them figure out their larger misunderstanding.

    How cool is that! Two guys I'm subscribed to, doing a totally controlled experiment together, with an awesome result, challenging another guy who I'm also subscribe! Great video guys, particularly when playing them synchronised! I suspect you are correct, this has not been done on the internet before! Keep up the great work!

    Toilet swirl is usually initiated by angular water nozzles located under the rim which will overpower any minute Coriolis effect.

    The size of the bath tub is exaggerated---I am not sure if this 'lagging behind or getting ahead' business is significant in such a small tub.I don't know how to reconcile this with another video by a Kenyan on the equator, showing clockwise rotation in a bowl a few feet north of equator, and anti-clockwise rotation a few feet south of the equator.

    What I'd love to see now is you both team up with Physics Girl and get her to do the recording right on the equator. Now that'll be something, ya?
    ...just that I don't want to wait 5 years now for the 3 of you to sync up. And I'm wondering about the logistics of playing 3 videos side by side by below??
    Ooo... lookie, while you both were making synchronized videos, here is my synchronized comment! Clicking the comment button in 3..2..1.

      The water cant go other ways in this experiment, and lots of other experiments shows the same effect.

    • Matt Pipp
      Matt Pipp 7 дней назад

      elonesnah that's my point. When the water goes the way you think it should, it's set up correctly.

      Kel Duck Right. Not sure how a kiddie pool on top of a piece of plywood falls in line with that. My impression is, they know it's 'set-up' correctly when it spins the way they think it should. That's all.

    This doesn't prove the globe or the spinning. It can be a moving magnetic field or whatever force that's moving the sky and everything in it above the Flat Earth! You can prove the globe only by taking a picture of the entire thing, and you can prove the spin by making a video of it spinning. Everything else is a theory. You got overexcited too soon.

    • elonesnah
      elonesnah 7 дней назад

      Boris Popovich
      But the earth rotate very slow, only once in 24 hours, or 0.000695 Rpm, speed is relative, if you were a giant holding the earth in your hand it would still only rotate once in 24 hours.
      Focault pendulum, eotvos effect, hurricanes opposite rotation in the two hemispheres, star rotation opposite in the two hemispheres, eotvos effect, tracking the sun and stars with an equatorial mount using only one axis of rotation, the suns movement is 15 degrees every hour due to the earth rotation, no matter from where on earth you measure it.. All impossible on a flat stationary earth.
      So what evidence of no rotation you got?.

    • Boris Popovich
      Boris Popovich 10 дней назад

      Kel Duck I am not claiming anything. I am disputing their claim. There is no evidence that we live on a spinning ball. If we were truly spinning, the oceans would be long gone.

    It also depends on how the water in a toilet mechanism is designed and on what side of the bowel it drains to. Better off using a sink.

    What foolishness. The guy did the experiment ONE TIME. True science requires the experiment to be done several times. Was the pool on perfectly level ground? He didn’t take that into account. Here’s one more thing, which way does the water drain at the poles? I guarantee that it would spin in either direction. Everyone in here is congratulating this guy but no one thinks for themselves. Sheeple.

    • Kel Duck
      Kel Duck 2 месяца назад

      Well most people read the description, they then find it was done 3 times each, so 6 times all up.
      Explain how non level ground will effect the rotation of the water?
      Your guarantee is worthless.
