When Veritasium gets it Wrong! - Trial by EXPERIMENT!

  • Опубликовано: 21 окт 2014
  • 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!

    Ok so this is exactly why so many of these younger "skeptics" worry me. "I have a theory and my test. Proves what I think" but then they don't try to disprove their own theory... and so while it makes sense and they feel they proved it. They are wrong but feel like they are 100% right and lash out at anyone who tries to refute them. I feel like were gonna have a dark period where a bunch of "discoveries" are made then 5-10 years later they are all disproved. This is why I question many theories ... And it can absolutely be a lack of understanding on my part but how many theories could be based of off one simple misreading or a misunderstanding due to a lack of our understanding of how something actually works. I mean look at how confident veritasium Is?

    Thunderfoot used water. The other guy used wadder. Not the same chemical. Would the velocity during the stream, Vs reduction of velocity at the end of the stream, increase the attraction due to reduced velocity.

    Veritasium's explanation isn't wrong... but the OH- and H+ ions (and stray ions) are Sooooooo negligible it doesn't make a difference. Just look up the water auto-ionization constant. The constant tells you on average how many OH- and H+ ions are in tap water.

    Now do this with a flexible plastic or rubber tube, and after the water is done, move the balloon toward the end of the tube to see if it deflects away or toward. I'm not sure how you can be sure the apparatus itself did not take on the negative ions otherwise.

    *There is an even more decisive way to test it.* If what he said was true, you could simply do a pH test on your (it obviously has to be) destilled water after it has curved around the charged object because the only positive ions that would be in the water now should be hydrogen ions, so basically protons or oxonium ions which they react to in water.
    H2O + H2O ー> OH- + H+ + H2O
    H2O + H+ ー> H3O+ => pKz(H3O+) = 0 => acidic
    So going by his theory, the water must now be acidic which cannot be the case because that would make chemical industry much easier if we could just analyze water into by letting it pass by a charge.

    If the water stream curves doesn't that mean one side is moving slower than the other? So could the charges object be slowing down the water closer to it? Though that wouldn't explain the repelling which you showed happening. Surely someone's done some proper research on this?

Even better that the answer is "X, but we need more work". The wonderful coda of science!

  • Niall Tracey
    Niall Tracey 7 месяцев назад

    There's a slight gap in the methodology here:
    When you move the charged membrane (balloon/cup) near to the droplets, you have already held it to the stream, which would give the opportunity for the water to gather charge as per Derek Muller, if that was possible.
    So now we've got an uncontrolled variable -- is the deflection of the droplets due to the pre-charging of the water, or is it simply the default behaviour of droplets in the presence of a weak negative static field?
    My initial hypothesis would be the latter, as the continued deflection of the stream does indeed appear to disprove Muller's theory.
    But we'd need to see the effect of the charged balloon on individual droplets that had never been subject to a static field beforehand.

    Hi Thunderfoot.

    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.

  • Arokace
    Arokace 10 месяцев назад

    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.

  • Liber Philosophus

    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.

  • Joost Ringoot
    Joost Ringoot 11 месяцев назад

    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 Год 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.

    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.

    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.
