What is the longest drinking straw that you can actually drink out of? Well in this video, we put the theory to the test. We started off with a one metre long straw made out of drinking straws taped together. We moved on to two pieces of plastic tubing, each 6 metres in length with different diameters. Then we tried a 10.5 metre tube over a cliff's edge. The maximum we achieved was about 7 metres though theoretically up to 10.3 metres is possible if a perfect vacuum is created.
Who in hell actually drinks out of a bottle with a staw????
no, not nearly everybody, straws are for cups.
+Northy Gaming who the hell are you hanging out with. If you have a bottle either pour it or take a drink from it.
***** ah ok yea that makes more sense
+Joe _ (LittleSwifter) Not even for cups, I don't use straws unless I get a take out cup or a smoothy/milkshake.

You would be surprised what lengths people would do if it meant not doing what they don't want to do.
This doesn't make sense... You still have to go down and open the bottle.
+Unlitflame You could set it up so that the tube branches out to several bottles and you suck all of them together.
Well, you'll have to do some sort of preparation either way. You could also have a cooled tank that can hold a certain amount of beverage and use the tube with it.

The actual height you can suck water up through a straw (assuming capillary effect is negligible) is 10.0 meters. The thing that was missing in the equation at the end of the video is the vapor pressure of water. You can't get a true vacuum that is adjacent to the free surface of water. As the pressure decreases, the water will vaporize and stabilize the pressure. At room temperature, this is about 3.169kPa. The final equation should be modified to (101325-3169)/(1000*9.8)=10.0m. This is known as Net Positive Suction Head and is used quite extensively in pump calculations.
Interesting. I learned something today.

I'd love to see you completely fill the tube with water, cap one end (leaving the other end submerged in a water bath), then raise the capped end up above 10.3m. You should see the water boiling in the top of the tube. (Assuming the tube isn't too flexible so it collapses under vacuum, too small for capillary effects to dominate, too heavy to be raised that high etc.). I've heard of this thought experiment many times but I've never seen anyone actually do it.

I'm super late to the party but theres one small issue with your theoretical calculation. (Please forgive me if someone else already mentioned this) But there is an additional limiting factor on vacuum pulling a liquid known as vapor pressure. For any given liquid its vapor pressure marks a point where if the pressure on the liquid drops below that point the liquid will simply start to boil rather than expand upward. The means a perfect vacuum is impossible so the pressure difference will be less than assumed in this video. Water has a vapor pressure of 2.4kPa so its theoretical maximum height would be a function of (atmospheric pressure - max(vapor pressure, applied pressure))*g*h. It only makes a few % of difference with water but for some liquids it's a pretty massive limiting factor. So fun video though!

Another experiment: Submerge the tube in the liquid. Cap one end, tie that end to a string, pull the full straw up the cliff. At some point the straw keeps going up but the liquid doesn't. (Above which level the straw will collapse.)

The production value and topics of these videos certainly have increased over the years :D I just recently have found this channel and the discrepancy (?) is quite noticable :D
but that's height based, so you can practically make as long of a straw as you want just as long as it keeps most of its length horizontal you should be fine
Chara Dreemurr atmos... nevermind
The Prime Critric: GRAVITY. Put a barrel of water ABOVE you and suck the water through a garden hose until the water reaches your mouth and you can stop sucking but the water will STILL flow out of the end from the hose... as long as the end of the hose is BELOW the other container it works...
Thiesen: PAYING ATTENTION. I said horizontal, not vertical.
Giggo Galac its just that even in horizontal tube the liquid would fill the straw and if the straw was long enough not come trough at all
the main limiting force here is gravity, if the tube is horizontal gravity is no longer limiting the length, however it will take multiple lungfuls to suck the liquid out.

This explains perfectly why all the water pumps, no matter how much power it has, can suck water from only about 7-8meters deep, and even a small pump in the well can push the water up tens of meters higher! Also I have wondered where the normal air pressure of 750Hgmm came from, and got that answered as a bonus! Thanks 😃!
Great point! You can push without limit, but you can pull only by reducing the pressure (with the limit P=0)! How to overcome the "theoretical limit"? Check the article " Two boys and a can of Coca-Cola ". I could not add a link but you can easy google it.

The density of coke is 1100 kg/m^3... So actual theoretical maxima is 9.4m. Just FYI 😜
thx! 😆
what if we use the liquid with least density,whatever it is.
+Surya Amay The least dense liquid is liquid hydrogen (least molar mass duh!) but it exist at a temp at which we wouldn't ☃. So the least dense liquid which exist at ROOM TEMPERATURE is pentane (not sure) it's density is 626 Kg/m^3. According to the physics that I know you can (if you can create perfect vacuum) suck it up to a height of 16.5 m. If somehow you were able to do this experiment with liquid hydrogen then you can take it up to a height of 147m approx. 👍🏻( I wrote what I know might not be right 😬😜😎). Happy KZheadbing.
Even then, the practical maximum would be around 7 m.
Ashutosh Jha piezometric height counting it's much less than that..plus if we take into account density . it depends on the diameter of pipe.
It would be interesting to see how far you could blow the liquid up the straw by creating positive pressure (Pgauge) at the bottom. This could be done by sealing the lid and adding a mouth piece. Theoretically no limit.

I think the problem is that as the drink gets farther up the tube, it gets heavier, and as it gets heavier, the negative pressure becomes less sufficient to pull the drink up. I think if you did it at an angle or with occasional horizontal sections, you could get some help from gravity
You can actually do more than 10 meters if you air seal the bottle straw interface for carbonated drinks as carbonation can produce excess pressure

If you had a long enough straw, you could only suction water upwards the length of 10 meters. After that water spontaneously boils
You should get an oscar for the intro
That was the most unexpected video ending ever.
So I don't wanna be THAT kind of guy but i think that, other than not considering the happening of cavitation, as many of you have said already, he is also neglecting viscous effects. I made couple of calculations and here's what i got. So let's say the fluid is water. From now on I am gonna use SI units of measure only because I am european, sorry if that bothers you lol. Anyways, to calculate the max height we can use the generalized version of Bernoulli equation: p1+0.5(density)*v1^2+(specific weight)*h1= p2+0.5(density)*v2^2+(specific weight)*h2+(specif weight)*hl, where hl is the head loss due to viscous effects. Let's say that water is moving with constant speed at 0,6 m/s (in the video the guy has made the fluid reach him after 10 seconds with a 6m long tube, so seems like a reasonable assumption). We can express the hl in terms of the friction factor: hl= f*0.5*V^2*h*(1/g*D), where D is the diameter (I used D=5mm). Now if we consider that initially the fluid has 0 velocity, 0 height and 0 gauge pressure, we can easily apply Bernoulli with losses. First we need to calculate f. I used the Colebrook correlation considering plastic as hydraulically smooth, to find f = 0.05. Last thing we need to set a minimum preassure, which would be the one at which cavitation occurs. For 25C, pmin= 3170 Pa so a gauge preassure of -98130 Pa. Now we can solve Bernoulli and find hmax=9m. Hope you enjoyed and let me know if you think something's wrong!!!
Actually I just realized that the flow is laminar, so we can calculate the friction factor simply as (64/Re) which gives a f= 0.024. In this case we have max h= 9,25m
how about using a big coke reservour and a tube running to the desired location and a small 12V pump pumping it through to your glasses? trust me im an engineer!
+SamD You can pump it in from the bottom because the pump increases the pressure above the atmospheric pressure. If you put a pump at the top to create a vacuum then you cannot beat the 10.3 meter limit.
Justin Childress oh..that actually makes sense.. But then.. isnt having a pump at the bottom even easyer to set up..
Yeah that'd be the way to do it.
But the Coke would go flat...
This is correct. You can "push" without limit, but you can "pull" only by reducing the pressure ( limited to P=0). How to overcome the "theoretical limit"? Check the article " Two boys and a can of Coca-Cola ". I could not add a link but you can easy google it.
The implications are endless...

This video is 10 years old, but it is still better than most videos on KZhead…
I learned about pressure more than 50 years ago. At that time, mm/Hg was the only unit of measure for pressure. To this date, all my barometers and other pressure gauges have a mm/Hg scale, because it is the only unit can grasp without thinking. Note that "Hg" is the chemical symbol for mercury, called Hydragirium in Latin. The generations before myself, they had their gauges with a "Torr" scale, where 1 Torr = 760 mm/Hg = 1 atm. "Torr" comes from Torricelli, the Italian inventor of the mercury barometer.
Science: finding complicated answers to seemingly simple questions
There are bore wells to get underground water, which are as high as like 200 ft, from which people suck water using a electric pump. Now, before starting the motor, it is critical that the there is water in the whole tube so that pump can start. I think this explains why. Since you can only pull water at 10m using vacuum, the pump can't suck the water using vacuum. So, it needs water capillary the whole way down, so that -ve pressure can be created by the pump at the top point of water.
Actually, you can't reach the absolute max height based on pressure alone (vacuum at the air/water interface), since water boils at around 2 or 3 kPa at room temperature. That's 2/3% of Earth atmospheric pressure, or 20/30cm before the 10.3m mark. Steam will continuously replace what the vacuum pump tries to take out. You don't get this problem with mercury since it's hard to boil, even in vacuum.
I love how after Nigel gets burned on the balcony, Nigel gives a look and immediately the Veritasium guy is no longer on the balcony.
what about using a wider dish? would more atmospheric pressure contacting a wider area influence the calculations?
But can it blend.
+Skandranon Banefire Pressure is Force/Unit Area, so increasing the area would increase the net force while pressure remains the same. :)
+Skandranon Banefire A wider dish would not affect the result because the atmospheric pressure only affects the straw's opening where it's submerged. Higher atmospheric pressure would increase the height to which the fluid could be raised from zero atmosphere at the top of the straw. That height is determined by the equilibrium between the weight of the sucked-up fluid pressing down and the force of atmospheric pressure pressing up at the bottom opening. Pressure is force per unit *area*; since the area of the opening is the same as any cross-section of the straw, the mathematics holds for various inside diameters of cylindrical straws.
What did u say?!?

It's 4am.. I was just looking at captain sparkles old let's play videos 30 minutes ago
This is the best quality 2012 video I’ve ever seen
I honestly thought they were gonna reveal some sort of new polymer making technique when i saw the thumbnail. Like, i imagined that you would be able to put some sort of short straw in a polymer in liquid form and when you dip the straw in gently the polymers structural property would change, or maybe an irregularity would cause the polymer to solidify the way super cool water does when when you introduce an impurity, and when you gently pull the initiating straw upward i imagined that somehow this polymer liquid would have a reaction to the increase in tension where the straw is lifting off and thus you would be able to pull the initiating straw out along with the newly made straw shaped polymer effectively creating a much longer , and potentially infinite, straw. But no. I got my hopes up. It was just a flexible clear tube in a cup filled with red juice.
If you could get a straw to reach the vacuum of space and dipped the other end in the ocean, wouldn't water keep flowing until the ocean was dry? I know that this doesn't count, because you couldn't actually drink from it.
Did you watch the video? Water can only go 10.3m high no matter what.
cbernier3 With a strong enough material the straw wouldn't collapse inward, the vacuum of space has more than enough vacuum power to move the water.
No, no such thing as a sucking force.
cbernier3 Vacuum, a human has a limit to how strong of a vacuum they can produce. I actually found a video that talked about the exact question I asked, I think it was on Vsauce. By the way, I was incorrect. But it was a question anyway.

Nobody: KZhead recommendations: yes
wouldn't the 10.3m change depending on your elevation?
Ben Dover It does. But that change is so small on that altitude scale that it becomes negligible.
What about the diameter of the straw? Wouldn't that change it?
MadDog0425 Well, it does and it doesn't. When your straw is small enough (smaller than 2mm in diameter) there is a capillary action that pulls the liquid up against gravity. With a diameter small enough (0.3mm for instance) you can get up to 12cm of elevation just by capillary action. Adding this to the 10.3 limit and you can get as high as 10.4 with a .3mm straw. However, capillary action decreases rapidly with diameter. Any straw wider than 2mm will no longer produce any noticeable change in elevation, limiting it to 10.3m with ANY diameter.
Alex Cani If the temperature of the liquid was different, would that affect the length too?
Jack Warren Well, supposing you are heating the water but not to the point of boiling it (because it would just leave the straw by itself) the only effect you would observe is the thermal dilation of water, wich would increase the volume of water contained in the straw without also increasing the mass of water in the straw, wich would indeed cause an increase in the height, but it would be also a function of the radius of the straw, and probably negligible. Short answer: not really, no. And just to clarify things, the 10.3m limit applies only to water or liquids that have similar densities. Less dense liquids would get higher, while denser liquids would do the opossite. Actually water happens to be a quite dense liquid with a quite high boiling temperature, so if you tried to suck up most other liquids (like ethanol or even engine oil) you would get higher than 10.3m.
Revisiting channel after 5-6 years..😍
Put tape around the joins to prevent air from getting through.
Is that the theoretical limit for a 5mm straw? Because trees use capillaries that bring water up 100's of meters.
ArrKayCee The diameter of the straw has no bearing on that. Theoretically, Atmospheric pressure = Density of water * Acceleration due to gravity * height Which means, Max. Height = Atm. Press. / (Density of water * Acc. due to gravity) Therefore, Max Height ~ 10.327333m Also, in the vascular system of trees, it doesn't only rely on suction. In addition to suction, it uses other systems to transport the fluids upto the top of the tree. Don't really know much beyond that.
Sushrith Arkal Thank you, that explained it.
ArrKayCee put a piece of paper towel vertically in a tub of water, the water will go up the paper towel, that's how trees bring water up their trunks.
I believe transpiration pull has a major part to play in that case
Adam is right. Transpiration and hydrogen bonds are the vast majority, if not all, of the tree effect.
