When Veritasium gets it Wrong! - Trial by EXPERIMENT!


  • Опубликовано:  2 года назад
  • Veritasiums explanation for the deflection of water bugged me.

    A week or so of experimenting later, I had a simple, reproducible experiment that demonstrated that their explanation was wrong.

    The concept is simple. According to Veritasium, positive ions come out in the water, while negative ones are withheld. This means that in an electrically isolated system, the first water out should be positive, while the reservoir at the top becomes increasingly negatively charged. However ultimately that water must come out too, and when it does, it should be strongly repelled by the charged object. In reality, that doesnt happen, indeed if anything its more strongly attracted, although this is probably due to the last water out moving more slowly. Either way its a pretty clear experiment for showing that the ions do not move back up into the tap as Veritasium suggests.

    Stunningly there is actually some quite recent stuff on this in the literature (last 10 yrs or so), although Im not so sure I believe any of it.

    Y'see showing something to be wrong is usually just the first stage in science.... you then gotta show you know whats going on by proposing a model that works.
    In the week or two of experimenting I did, I got enough clear results to show everything is wrong! I have no coherent explanation that merely explains the obtained results, let alone one that can be used to predict unknowns.

    FYI, the cones at the end are called Taylor cones and are the core of electrospray which got someone a Nobel Prize in chemistry!
    Kinda makes it even more weird that its so hard to come up with a fully coherent explanation of why a stream of water is deflected by a charged object.

    -Simple things don't always have simple explanations!

    Kelvin dropper has to be seen to be believed!

    Have you tried it with DI water? If it has the same effect then it might be the case that the ions aren't what's causing the bend

    Has this been run using deionized or distilled water? It would be interesting to have two streams, one normal tap water ion concentrations and another deionized, running at the same flow rate and then comparing the deflection both upstream and downstream. High speed could prove illuminating. Of course for completeness the same should be done with a discharged balloon.

    I'm not a scientist so I could easily be wrong but could the ions be going to the metal with the sinks tap in Veritasium's video? Either way...why do this to him... There's so many other people who deserve your negative(well technically positive) feedback. Or were you just kind of at the bottom of the bin when you decided this? And ultimately, I think you said something about why scientist didn't say something at the time of his video, well that would probably be because of the majority(if not close to all) of his viewers are probably people who wouldn't know for sure if he is right or wrong.

    I think your model works better. Anions in an aqueous solution will typically be one of the lesser solutes, considering water itself and other cations mixed in. However, "charged" particle interactions are one of the weakest links in the molecular world. It would likewise then be unsurprising to see the interaction become nill at higher velocities. I think the repulsion at the end is explained by Newton's third law.

    Uhm... Veritasium is actually correct. Do this with larger objects over larger amount of time, and touch the pipe... you will get a small electric shock. Obviously this does not happen if you have an plastic pipe.


    When I've been doing sports, I somehow often gets electrically charged (like the cup). When i first enter the shower its all fine and i can touch the metal piping, but after a min or so i get small but unpleasant electrical shock when I touch the piping.

    An explanation that is in my opinion consistent with both your experiments and the experiments of veritassium, is this:
    Water is an equilibrium of ions.
    The negative object attracts the positive ions and repulses the negative ions. Some negative ions escape via the drops at the bottom and some dispose their charge at the conductive metal tap of veritassiums experiment, some just stay at the tap.
    The result is a slightly positively charged waterbeam that is sufficiently charged to pull the water towards the negatively charged object.

    Perhaps when veritasium said that the polar nature of water would only cause it to flip and not move because there would be equal attraction and repulsion is wrong, perhaps since the molecule's positive side is turned towards the cup it means as its close to the cup than the negative side the attraction force would be marginally greater than the repulsion force. Intuition tells me that it wouldn't produce enough of a difference to cause that much change in the flow but it's a thought

  • Crooks and Crafts
    Crooks and Crafts 3 месяца назад

    +Thunderf00t If the stream of water is indeed neutral, then shouldn't it be attracted by either positive or negatively charged objects? Correct me if I'm wrong, but didn't Veritasium's video show that one charge repelled the water, while the other attracted it? If so, then how could the stream be neutral?

    To be fair an engineering pleb like me would see no problem with this theory. Apply an electric feild and get an electric charge. From that feild we also get a perpendicular magnetic feild, which would attract the positively charged water. However given this doesn't hold up in reality I would be interested to see actual tests done. Perhaps use an inductor instead of a balloon to retry the experiment.

    However I prefer your methodology with the Kelvin dropper.

  • The Mad Hatter

    I think I know why the water droplets tend to move away when they fall. Imagine if you have a pendulum, if you push it one way and let it go, the pendulum doesn't immidiately stop in the center, it keeps moving till it gradually stops in the center. Likewise, the water is kind of acting like a pendulum in that it doesn't​ flow in the center when you move the balloon away.

    This system is such a great example of how you end up with non-linear effects when dealing with realistic systems, and how all the nice approximations physicists use break down.

    1.) Liquid water is a conductor, but it is not close to an 'ideal' or perfect conductor. As a result ions re-arrange themselves to maintain as low of a potential as they can possibly achieve. If there were an infinite amount of ions (or a very large number of positively and negatively charged ones), then the water would attempt to maintain a zero potential. Unlike a perfect conductor the ions in water are not smeared over the surface of the water, although they are still localized.

    2.) The water itself is a fluid, and is moving in response to gravity and the electromagnetic field itself. This is not at all what you deal with with ideal fixed conductors. This results in a two way non-linear coupling ; the electromagnetic field changes the shape of the waters surface and changes it's movement. The changes in the shape of the waters surface and it's movement result in changes in ionic concentrations, resulting in changes in the electromagnetic field. This makes it a difficult problem mathematically.

    3.) In addition, you have the fact that the surface charge on the balloon may rearrange itself in response to the electromagnetic field of the induced surface charge of the water. So there's that. That adds another layer of coupling here.

  • Mecca Miles
    Mecca Miles 3 месяца назад

    Wouldn't a better falsification experiment consist of the use of deionized water? -Veritasium's claim is that it is not the polarized water bringing about the observed effect, but rather, the ions coming out of the tap; therefore, to prove his hypothesis wrong, simply use deionized water where the only variable is the water itself and, concordantly, the water molecule's electric-dipole.

    Also, it's worth mentioning that simple logic can falsify his claim. If the electric dipole is not the cause of the deflection of the stream of water, but rather, the dissolved ions in the stream coming out of the tap, then the ions will not affect the water in the presence of a charged object, such as the cup, because the errant tap-water ions only act as a sort-of electric middleman between the water and the charged cup.

    That said, great video. Thanks for sharing.

    Revisit this now that you have the high speed camera. Might answer some questions. Isn't there a way of reading the charge on the outside of the tube as the water flows? Maybe a feather with a background gauge. Does the charge change on the drain when you introduce the balloon? That would tell you at least there is something different between drops and a stream and introducing the static charge.

    It is such a good feeling when you're first defying an effect that makes Kelvin water dropper work, my hands are just itching to write a comment about that and then you do actually talk about that as well and in the end you do prove that this effect can be shown when droplets form. My only complain is that in your veritassium video you said that ions move slowly in water: well, duh, electrons' directional movement in metals is pretty slow as well but because there's so many of them they still might form a considerable electrical current.

Issue #1: You are not using enough water to disprove this theory. #2: You are moving the balloons closer at the end of your "experiment". #3: Vertasium did not say ions, he says charge. You, in your very poor understanding of science, jumped to and made that conclusion. Again, please stop making bad science videos for your own ego. Your false information and poor scientific principle cause as much damage to science and people as anti vaxxers and flat earthers.

    Could you run this experiment again, but with a restricted flow rate so the stream becomes droplets closer to the glass tube. This would result in the water having a lower velocity when passing the balloon, and thus a longer time to experience the pull/push from the balloon, and thus a greater visual effect for demonstration purposes.

    You know... I wonder how effective showing differing experiments on video like this back and forth between scientists would be at showing people what science really is and why it works. I think part of the issue with people 'believing' in science is the fact that they are always being told what the end result is instead of seeing how the conclusion was made and how it was checked and verified. I know this would be very difficult to do in many cases... but I think that instead of simply showing how "right" science is... showing how getting /to/ the right answer with science is effective.

    I imagine it is a lot like being in higher end science classes where you need to prove or disprove something through an actually presented experiment. I do think the major flaw with an idea like this is how solidly most science already is... but a skilled teacher could present scenarios in a wrong but possible fashion and have those they are teaching work to show how it is incorrect.
