so THAT'S why I am 75% water.

ok lol

Would that not just be caused by water naturally dissociating to H+ and OH- ions?

@@lukeh9800 that’s an interesting point, but the concentration of these ions are 10^-7. To me that seems pretty low to get the entire stream to move. What do you think?

​@lukeh9800 the cause is indeed that water is a polar molecule, or more precisely the presence of a dipole in water molecules. Veritasium is completely wrong here, as a competent high school chemistry student would be able to explain.

It's debunked in other videos. Though it seems I can't post the name of the channel that has the video@@markrempel3355

@@mcbill7352 isn't it because it's both polar and has ions present? What if you were to do the experiment with an ionized, non-polar liquid?

Except the weight of the huge magnet and the ballast you'd need to keep the boat balanced are probably going to increase the boat's inertia to more of an extent than gravity could pull the thing down into the depression, thus rendering the whole thing useless...

Robert Faber mythbusters put a fan in a boat to power it against the sail, and everyone thought that it wouldn't move because of canceling forces but, surprisingly, it moved forward. This might have a similar reaction.

xanatosking01 Oh, my hypothesis is only as good as the next man's, I don't expect it to be absolutely accurate...

Newton's 3rd Law. The water is also pushing back on the magnet, upsetting the balance of the boat and causing it to lean backwards, which would cancel the forward leaning.

zulrang its pushing back the magnetic force, not the weight of the giant magnet

Distilled water and deionized water are not the same thing.

I just did all these experiments and plus some more: tap water, distilled water, deionized water, ethanol and acetone all work! The last two do not self-dissociate and are terrible at dissolving ions, so...dipoles it is ;) Thumbs up for your chemistry teacher.

The water through our taps goes through many stages of purification.

When water falls, it interacts with the air and gets rubbed. This means the molecules THEMSELVES become charged sort of like rubbing a balloon on your head. So this works on all liquids

Hana You still got a lot of ions in tab water. Especially HCO3 and Mn/Ca - ions. That's the reason you can't just use tab water in laboratries but need deionized water (not destilled water actually)

hilarious

+RaindropsBleeding I remember that scene. It was really cool indeed that they paid attention to that sort of things. I would never have thought of it (then again, I'm an art historian, not a physicist)

nice video and I really enjoy

What??? OK, I never saw the movie, but as I understand you, you're saying that the hot air balloon flew better in the (hot) air over the boiling lake than it did over the (cooler) air on the other side of the lake. If I understand you right, that is completely backwards. Unless there was thermal updraft over the lake, the balloon would fly LOWER over the lake because THAT air would be closer to the temp of the air in the balloon (i.e., less dense that the air NOT over the hot lake)..

@@markmarkw1919 I'm not sure how you managed to read exactly the opposite of what I wrote, but your knowledge of physics is correct, and lines up perfectly with what I actually said. Were you just hoping to hold the microphone? :)

@@RaindropsBleeding No, I meant what I said. I was puzzled, because I was pretty sure you knew what was going on, but couldn't figure out a way to interpret your phrasing to agree with that belief.

This

There is ZERO chance he hasn't heard about it @@stackowoflow

I would link the video if you find it important. However Veritasium linked a paper explaining the water deflection, so I still think he's right.

@@davidb2885 A paper existing doesn't mean the paper is accurate

He linked a peer reviewed paper that says that the dipole thing is wrong. He kind of missrepresents it, because it does not talk about ions dissolved in water, but induced charges. But that gives a lot of weight to it, even though thunderfoots experiments seem to prove the opposite. I am a chemistry teacher and have always used this experiment with the common explanation. I am no physicist though, so I don't understand how dipoles interact with electrical fields and why a electric field would not exert a force on the molecules. I always explained to the students, that the force at which charges are attracted or repulsed is dependant on the distance between the cup and the charges in aligned dipoles the distance between opposing charges is smaller than the distance of same charges, therefore results a net attraction. But now I am not so sure, if this explanation is true, if there is a peer reviewed paper that says otherwise.

This explanation bummed me out as well. But it can easily be verified by redoing the experiment with distilled water (or even better de-ionised water). Then allmost all ions have been removed and according to Veritasiums explanation the effect should no longer occur.

Jochen Deferme Yep... I'd guess it has something to do with moving charges, since the charges on the cup moves relative to the water current, but...

I agree with Thunderf00t. The individual ions are only found dissolved in water or other solvents and cannot exist outside of the as they form ionic compound crystals and so they cannot also "go to the tub". Without a polar solvent, ions cannot be separated from their respective compounds, so movement into air (non polar mixture of gases) would neutralise them instantly. A better explanation would have been that the cations in water would fly out into the air and neutralise the cup charge, which doesn't happen. (It's called electrostatics for a reason - plain water and air are insulators for electricity). The explanation is actually the one that our friend told us it is wrong! Because water is a polar molecule it is attracted by the charged cup and for as long as you keep the two close to each other.

So the key difference is whether the water finally going down into the sink is charged or not. It can be easily checked with a pair of oppositely charged plates under the cup forming a uniform electric field at a direction perpendicular to the initial deflection direction of the stream.

Yeah. I thought that one sounded iffy

Baby, I'm attracted to you like positive droplits are attracted to a negatively charged plastic cup, just let me swirl around you, cuz I'm falling liquid...

That’s actually good, according to _Forgetting: The Benefits of Not Remembering_ by Dr. Scott Small. In it, he quotes Francis Crick: “We dream to forget.” And if we didn’t sleep and dream, we would go insane.

+Anthony W. no it should be colder air descents ;)

+Anthony W. Hot is always relative to a context, so 'hot' always means 'hotter' in the absence of any other designations of heat

Insert 'hot' air into a vacuum-chamber; do this experiment twice (one injection in the top and one in the bottom of the chamber); have a pressure-gauge halfway up the chamber to monitor the rise in pressure when the air is injected; if hot air truly rises the pressure-curve belonging to the bottom-injection will come to an equilibrium before the top-injection-curve as rising-up air would fill the chamber faster from the bottom than from the top. However the opposite is true due to gravity (the hot air from above fills the chamber with help of gravity while the bottom-injection has to fight against gravity. So hot air does not rise; it just isn't as strongly attracted by gravity per volume than cold air, therefore cold air beats it in a race into a gravity-well

Mans not hot

DreadX10 Yeah so... buoyancy, like he said in the video

Yes

What question?

The negatively charged particles repelled upward dissipate into the faucet itself, so the faucet would become slightly negatively charged. You could probably observe that by hanging a human hair next to the faucet, which should be either attracted or repelled, depending on the latent charge of the hair/the hand holding it. Likewise, once you tried to collect the positively charged water particles, they would rebalance their charge with that of the vessel you caught them in, and the tool holding that vessel, etc. So it would be pretty difficult to actually collect the charged water. Also, the positively charged particles in the water are protons which are thousands of times heavier than the negatively charged particles, even though they have an equal-but-opposite charge. So it's almost always the negative charges that get moved around. You could negatively charge water by attracting more negatively charged particles (electrons) toward it; there's probably a material other than plastic which would do that (obsidian, maybe? There are a lot of them with their own static electric strength values and directions, but I don't remember what they all are. I think I recall, though, that plastic fabric + an obsidian rod would create the greatest charge differential, so that's why I said obsidian here).

Thuderf00t just released a video about this

thunderf00t?

Yes

Think there are 10^-7 mol/L hydronium ions in pure water (that's why pH = 7 right?) - the explanation in the video is that small imbalances in charge can be amplified by this apparatus through induction

Also tap water's highly chlorinated . So you got your Cl- ions right there .

Josh McGillivray Youn are right on the hydronium and hydroxide quantities, but the water you get out of your tap contains plenty of ions. i) Cl- ions (as mentioned below by Adhvik) ii) positive ions such as Na+, Ca2+, Mg2+ and so on. iii) other ions I think it would have been cool to prove that the explanation about the water stream deflection is right by deflecting some stream of distillated water...

+Federico Masini I'm guessing that it wouldn't work very well with distilled water, since there would hardly be any ions in it, just hydronium and hydroxide.

+Veritasium However, you did say "even a nonpolar substance with dissolved ions in it would do the same thing". I thought that nonpolar substances couldn't dissolve ionic compounds, or with any effectiveness. Am I wrong, or does the tiny amount of ions that do dissolve enough to create this effect?

Even with infinitely pure distilled water, an equillibrium is established so that the concentration of OH- and H3O+ are fixed, at 1x10^-7 mol/litre for each. I would hypothesize that there would be less movement of the water in presence of the cup, but still a noticeable amount.

Living in CA, yes.

You obviously have OCD.

Me

Yes and no. Water does, under some conditions, dissociate into H30+ and OH-. However, it is unlikely that there will be enough off either to have any meaningful effect, even on a stream that small. EDIT: Thanks MBogdos96 for pointing out my mistake. Fixed.

Christopher Pilcher Ummm... I think you made a pretty severe typo friend. It's OH- and H3O+

You are correct! Man, I am really glad I didn't make a similar mistake in my chem final last semester.

Christopher Pilcher Yes. That would've been horrible for you. :P

Wolfgang Kenshin Or, I somehow manipulated the electrons to make actual OH+ and H3O- ions. I can just taste the Nobel Prize now. :P

I tried it with destilled water which though it still features ions is greatly cleared of dissolved substances. Therefore the effect should be significantly lower than in regular water. I also tried it with salt water which should show a greater effect. But on a first glance the effects were nearly identical. So, though I find Derek's explanation very compelling and even more convincing than the one you find virtually everywhere (which can not be said from Derek"s - I don't know where he got it from)... the experiments so far do not fit the ion explanation. But since then Derek had put out some claims about the "true nature of things" that stirred the pot, so I guess that video was one of the first tries to bait a controversy that failed to catch on...

Hey guy 9 years from the past. We actually can, no problem. Stomach acid is hydrochlorid acid with a pH around 1, that'll make clean work of pieces of iron that size. As for whether or not it's harmful I can't say, but I doubt it is.

wha

Lol three years later, but I think the reason that happens specifically is because of the surface tension being broken (making little 'divots' like he showed in the video), and so when two pieces come close to one another they stick together because it requires energy to move them out of the combined divot.
