      I wonder what Destin would think about the accents from somewhere like Liverpool or Cornwall. They're not your typical British accents.

      @Stephen Benner The odd thing is the Alabama accent doesn't sound dumber when you weren't raised to perceive that.

    When I read something that makes me uncomfortable or is something I disagree with I tend to skim past it.
    I've learned to catch that skimming and go back to understand what it is that I disliked, often I find a new perspective or or a truth id rather not listen to.

      Really cool experiment and great life lesson... Don't just hear people, but focus on listening when you communicate. So simple, yet we are all guilty of "tuning people out". Thanks guys!

        I think this pretty intuitive, just the triangle law of vector addition and basic inertia. Force after leaving the jet = 0(except for gravity).
        It looks trailing coz, the component of velocity (of the end of the pipe) is always greater than the component of the water drop in the same direction(cos theta). It is basically a horizontal projectile.

              Its not easy to admit when you're wrong, I imagine even more difficult on a public YouTube video. Sometimes the lessons we learn about our selves can be even more valuable than the ones we learn about our universe. I'm proud of you for admitting your faults, it will help you learn from them

                Fear of being wrong is an emotional pain that causes the human brain to ignore information that is causing the pain. You experienced it with water. Next experience it day trading thousands of your own dollars if you really want to understand this part of your mind.

If this is the feeling you are hoping to instill in your viewers, you guys have succeeded with this one outstandingly. I hope everyone can experience this joy in learning. Thanks!

                              I know I'm late but this is so funny to watch you and Steve basically debating the Coriolis effect from a fixed frame vs rotational/translational frame 😂

                                @Matthew Bowles that's where the point about frame matters. If you set a fixed frame then yes the droplet stops rotating, if you have a rotating frame then no, the droplet continues to rotate but it "lags". That's literally the argument they are having 😂

                                @haltorne.mp4 But the droplet is not affected by the sprinkler system so it's not technically rotating anymore (not with respect to the sprinkler)

                                @Matthew Bowles what does it not have to do with this.. the Coriolis effect is simply the displacement of the Coriolis acceleration, which is acceleration due to a projectile and a rotating body... The water is the projectile and the rotating body is the sprinkler system...

                              btw. there's a section in Feinmans autobiography about trying a similar lab experiment. It was about the same kinda lawn sprinkler sucking in water put under and the direction it'd go afair. (:

                                        This is an interesting empirical observation of a physical phenomenon. The physics behind it are more complicated and the explanation in this video is not adecuate. Both these guys are intelligent but it would require someone with a stronger background in physics to explain it properly.

                                                  Your insight at the end to understanding someone’s POV was just as big a takeaway as the actual experiment. You are truly making us smarter everyday and for that thank you.

                                                    Paused before experiment started. The discussion is over the direction of the water, but that's problematic. The droplets/molecules of water do not curve outside of gravitational effects, they must travel in a straight line after exiting. The observed collected stream/jet made of those parts, however, trails behind each nozzle.
                                                    Destin's idea that the stream or droplets will come out with forward momentum at an angle ahead of the nozzles is understandable but should only happen to a small amount of water, for a short moment, if the spinning nozzles come to a sudden stop.

                                                      Second experiment done, observations made. Had to watch twice, will probably have another go after writing this. Mind blown in the best way. While I'm not nearly as educated in physics as Destin, I too was made aware of some arrogance and being stuck in what I expected, though I wasn't discussing or arguing with another person.
                                                      (Now that I've seen the video, I browsed a few comments and...) I share Johan Ung's appreciation for the insight Destin shared. Be it an argument with a person or just understanding of an idea, we can all benefit from pausing to absorb everything, be open to some things we hadn't considered before, and be able to learn. Great video on several fronts. Thank you, Destin and Steve.

                                                      Paused again after first experiment. Both of them right in different ways. Physics 'Tubers 2, VoltisArt 0.
                                                      Inward jets...should each be running like the fist experiment, with that trailing tangent not reaching the central pivot. How close it comes depends on water velocity...maybe. (The more we learn, the more we realize we don't know.) I think the observed stream curve could be a little more interesting.
                                                      Edit while I work on reaction #2: The tangent was never trailing....the stream was. Big clue to the result but so counter-intuitive!

                                                    if there was no velocite outwards, mind you, not by centrifugal forces(don't exist) but by the existing pressure from the water system, the effect would be the same, only with inertia.

                                                      Please correct me if I am wrong, though I naively think there is an easier way to figure out the correct answer: Consider a drop of water, after leaving the pipe, since there is almost no force in the plane of rotation, it maintains its angular momentum. Therefore, when it "flies" away from the "rotation" center, the angular speed goes down, thus "lagging" behind. When it "flies" towards the "rotation" center, the angular speed will go up, thus "running" in front.

                                                          not true actually. The droplets are not rotating after they leave the spout, so why would angular momentum come into play?

                                                              Excellent. Thought provoking conclusion that makes a perfect lesson for the world.

                                                              Don’t fight. Try to understand.

                                                              Obviously, once you do understand, you might still have opposing views. At that point, I guess you have to fight.

                                                              Peace and love. Peace and love.

I think I encountered SED from a colab with Veritasium, and I encountered Steve from a colab with Matt Parker. I love how the YouTube science community is so interconnected and you can see some brilliant people doing brilliant things together.

The comment about listening and taking time to understand the other person's point of view was perhaps just as fascinating as what I discovered about the water. Just recently, I learnt when we have an existing belief or (unknown) existing assumption our brain finds it difficult to take in new information. Years ago I read one of Debono's books on thinking and one suggestion of his is don't believe / disbelieve in anything 100% - so it allows our mind to absorb new info. He had a wonderful diagram of a ring over a stick suspended above a "pit of ?iniquity" As you learnt more about something you could move the ring along the stick toward one end belief or the other end disbelief. 100% belief or disbelief meant the ring would come off the end of the stick and fall into the pit. If it stayed on the stick, it was much easier to absorb new info and thus be able to move backwards (or forwards) on the stick. Cheers, David.
