  • Steve is a really smart guy if you ignore the British accent" **angry tea clink noises**

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

    • @Tom Edwards was it an alcoholic rage ? Lmao

    • I spilled my earl grey tea all over me crisps and crumpets

    • End the fed.

  • you both are great! 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. (:

  • Two high needy guys playing like 6 year old

  • That's the coriolis effect. It's taught in mechanical physics.

  • You are wrong.

  • He's English.

  • I have found over the years that lessening to 2 or more people that if you combine the thoughts together you might come up with a better solution because most everything can have multiple ways to get things done

  • 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.

  • nah, for the first one, destin is totally wrong. if it was a question on a physics exam, steve would get the point and destin would get it incorrect

  • so i have a turbo machinery exam and i couldn't understand the velocity triangle of the centrifugal pumps until I remembered this video and i got it once I saw it, thanks man

  • WARNING: This video contains no laminar flow. Watch at your own risk!

  • Hello SmarterEveryDay - I miss videos on the Cavendish expertiment (directly measuring gravity) on IT-tvs. you too ?

  • What a great collaboration, came here after watching a Steve’s video. 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.

  • The second case is a good demonstration of the Coriolis effect.

  • Destin sneakily teaching everyone vector addition lol

  • this is a classic physics puzzle where there is a serious physics principal that just breaks the way a brain thinks about things experientially.

  • The wisdom at the end was smarter than the physics puzzle =)

  • 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.

  • Like because of the conclusion

  • youtuuube awesome

  • I love Smarter Every Day, and Steve's Channel. I think I encountered SED from a colab with Veritasium, and I encountered Steve from a colab with Matt Parker. I love how the IT-tvs science community is so interconnected and you can see some brilliant people doing brilliant things together.

  • Thanks J-Roc

  • Hey DESTIN. There is a video called “spinning t handle in zero G”. Very interesting. I would love to hear you explain why spinning it in one direction cause it to intermittently spin on a different axes

  • Great video, thanks. 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.

  • In Phaeno Science Center in Wolfsburg, Germany, there is an exhibit demonstrating this very Phaeno-menon. However, I thought it had more to do with the Coriolis effect.

  • It'll be very interesting to see the light version of this. Revolving optical fibres that are transmitting different colours

  • hey Destin i am a big fan, have you heard of the Hilsch Vortex tube? the device that sends ambient air in and seperates it using black magic or wizardry and outputs hot and cold from either end?, just wondering if you would kindly explain why this happens as im clueless and i want to get smarter everyday :)

  • Two countries divided by a common language, They say

  • My intuition: as you move closer to the center of the circle, you traverse more of the circumference of the circle in less time, so even though water droplet is going at a constant speed, relative to the spout it looks as if it has travelled a farther distance.

  • I love this guy

  • More with Steve please

  • You and Steve are awesome !

  • the thing with disagreements is a great lesson - reminds me of this practice in programming where people often find the issue with their code simply by describing it to somebody else. this forces the programmer to zoom out and sort of change their perspective.

  • wholesome dude

  • Wtf happend? Its so weird!

  • I understood your perspective, and it is awesome!

  • Excellent takeaway moment at the end. I appreciate the reminder. ;)

  • This is impossible. You broke Matrix.)

  • Is this just a very clever and subtle way of illuminating the political and ideological divide in the US?

  • If you learned from rewatching this video, Destin, you should read "12 Rules For Life: An Antidote to Chaos."

  • “When I disagree with someone it is imperative that I stop, I listen, and I don’t move on until I completely understand the other person’s perspective”

    • @Bassem B. That's true, Bassem, I suppose a small percentage of all humans will behave mysteriously no matter what the situation is or how ineffable their thought-process.

    • @kchen075 Thanks for your discussion!

    • Ah wait a minute, it was because of the premier feature on youtube. Mystery solved.

    • Dislikes could be on a whim. For example, I liked this video, but I could very easily just press the dislike button just because I can. There are no consequences for me nor are there any for Destin. Some people(I don't know exactly who) just press the dislike button on every video they encounter whether they liked it or not. And of course there are the people who actually disagree with some point made in the video or something happened in the video that made them upset enough to dislike. And people who misclick the like button. Those are 5 possible reasons people dislike a video.

    • Dislikes can be a mystery. I've seen dislikes on videos of kittens and puppies playing, anything.

  • Tracer rounds fired at night from a machine gun tracking targets in the air appear to be ‘curving’ in flight also.

  • Yeeyee I am from Alabama

  • Paused at 1:58. My hypothesis is that the force pushing the water outwards is converted to force pushing the water inwards at the curve. The shape from above will look something like a cone as the water is pushed inwards following the spinning motion of the contraption.

    • My original hypothesis was definitely wrong, I didn't think about the vectors of force correctly. I think the curve in the metal pipe creates an inverse effect on our eyes. Very fascinating!

    • Paused again at 3:15. Destin, I believe you are wrong about the simpler version as well. The way Steve described most people's intuition would be accurate, as a projectile that is released from a rotating object does not continue to rotate, but remains on the vector it was traveling at the moment of release.

  • Loved that profound observation at the end there - that's great stuff. After my Brain got done exploding for like seven minutes I too came to an interesting observation that you seem to also have uncovered some limitation in the human brain that even after having it magnificently explained with slow mo and graphics and everything the (my) brain still processes this overstimulating physics as an optical illusion of arcing curves that frankly seem to completely defy logic, and yet, once explained don't. Yet another brilliant video Destin - going over to check out steve moulds channel now :)

  • Just a thought, maybe he forgot the air resistants?

  • It’s funny how you say when you think the other person is wrong you stop listening to them, because one time I thought I was arguing with this one guy only to figure out later that we were both arguing the same point, just like you two 😂

  • 9:50 how Americans are seen around the world

  • "Seems like a smart guy if you can look past the British accent" - Forrest Gump - 2019

  • Isn't it a Lagrangian VS Eulerian point of view thing ?

  • The youtube collaboration of greatness! Can't wait to watch!

  • this channel became smarter every couple month

  • 0:20 Stephen looks so high🍃😅

  • that really messed up with my brain

  • Who else thought of the treyarch symbol when he spun it

  • Pausing the video and trying to visualize the water path made my brain melt. But when you see it, it seems so obvious.

  • If you take the snapshot of the first example and start bending the end of the pipe along with the water coming out, you finally get the same shape when the end is inward
