I think increasing the viscosity would feel like switching to a bigger gear on a bike - it gets harder to move, but you can move faster by moving your feet (or arms) less, so it has about the same speed either way
Which makes me think though (He may have explained it in the video already and I am just too impatient to watch it all) won't there be a certain point where the viscosity is so high that pushing basically becomes so hard it's unachievable, and therefore swimming in water would be faster. Because when you up the gear on a bike, there is a certain point especially at an incline where you just can't physically push against it. Although I assume this video is also talking a little hypothetically, as in, if you had infinite amount of strength to push against the liquid
And now we know that it wouldn't be more interesting at all. It would be exactly the same. Unless you use a syrup that's at least 3x more viscous than water.
That is always misquoted to mean the opposite of what it was supposed to: “the blood of the covenant is thicker than the water of the womb.” As in, the things you agree to and buy into have more influence over your life than your family. Make or join your covenants wisely
I think with the more viscous liquids you can swim the same speed but it takes more exertion. The amount of force that you’re able to apply on the syrup is greater than the amount you can apply on the water, but that still means you have to push harder. So with the really viscous syrup, you reached the limit of the amount of force that the turtle could apply so it couldn’t swim as fast. If you had significantly stronger motors it might still be able to swim as fast or only a little slower. It makes no sense that an effect would just disappear outside of a specific range of viscosities. It would have to slowly fade (meaning that the speed slowly decreases) as the viscosity increased.
I agree. The turtle swimming slower is not a property of the liquid but of the turtle system being too highly damped by the syrup. It ain't got the gas!
Exactly, the skin drag vs form drag argument didn't make much sense, your reasoning was what I was thinking as well. As long as the swimming object has enough power to move the propellers/flippers with the same rate, they will move with the same speed.
It's not a matter of the effect disappearing. It's a matter of one of the effects being 'used up'. When viscosity grows up from water, if you use the SAME amount of strength, while you need more strength to move through the more viscous liquid, more of the strength you used to move actually is applied. But at some point, the increase in strength needed will be higher than the gain from higher efficiency. Let's add some numbers to it. Let's say you move at 1km/h if you put in 100 energy in water. You put in 200 energy but because the water is thin, only 100 units of that energy are actually propelling you forward. Now, you put in 200 energy into a more viscous syrop. Because it's more viscous it takes 150 energy to move at 1km/h in it, BUT thanks to that trait, 150 energy from the 200 you use is also propelling you forward, so you still move at the same speed. Now, raise the viscosity much higher and you get to a point where to reach a speed of 1km/h you need to provide more than 200 energy, say 210. It doesn't matter that almost all the energy you use is used to proper you forward (it cannot be 100%, as that would be a solid object). You just have to raise the energy to move faster, so for example, you will have to use 212 energy. That's 12 energy more than you could have used in the less viscous liquids. This is the point made in this video. The moment you raise the viscosity past the stage where the efficiency increases at the same rate as energy requirement, you have no choice but to increase the energy input for the same effect. But if you are comparing your best time in water, you simply CANNOT increase energy input, hence you WILL be slower.
@@bscutajar But they need to input more energy for the same effect, therefore no, you cannot swim at the same speed in a much more viscous fluid as you can in water. You cannot suddenly become stronger simply by swimming in a thicker fluid. If you could, then your time in water would be shortened and you still would have been doing a worse time in the viscous fluid. You are changing the problem here from a body with a fixed ability, to two separate bodies with different abilities. That's an entirely different experiment, and one that never needed any sort of confirmation as it is absolutely clear that so long as you provide enough energy, an object can move through literally anything at any given speed (below the speed of light, and assuming it can withstand moving through said environment).
I remember when Mythbusters tested this. Still interesting. Imagine going for a swim and having to shower afterwards not to wash off the chlorine, but the stickiness.
As a swimmer, I can say that these results are true under the assumption that swimmers apply a constant force on the water, and in some ways this is true. But for strokes that rely more on a gliding lotion the added resistance from the water will make a huge difference, not to mention the added stress on ligaments and joints from the higher impact forces. I mean it’s a rotator cuff injury waiting to happen. But for plastic turtles who apply an almost constant force it’ll probably work just fine.
Great thought experiment! I would try an experiment where more of the toy is more submerged. Right now it seems the turtle is staying mostly out of the viscous liquid, so the increase in drag is only experienced by the belly surface. As a swimmer, you aim to go as high as possible, but majority of your body is still underwater. Try a toy submarine!
As a swimmer, what I can tell you is that if you were to put me in syrup, I might be able to swim just as fast, but I wouldn't be able to swim for nearly as long. I believe this is what we were seeing with the turtle in the extra-thick syrup. The first thing you need is enough power to propel yourself forward in whatever liquid you're in, and if you don't have enough power to push against the fluid, you're doomed. Indeed, swimmers often make things harder AND easier on themselves by wearing drag suits (or even just all their clothes) and wide paddles. Swimming with hand paddles makes you much faster, but your arms tire out a lot sooner. You can push harder because the surface area of your hand becomes bigger, but if you lack enough musculature to push yourself forward, it doesn't really matter. You could pair your paddles with a drag suit to maintain the same speed as unencumbered, but you would fatigue sooner. (This would be a valuable exercise for a swimmer-basically, it's just building muscle and fatigue resistance over a shorter time. It may cause joint problems, though, because you're really loading the shoulders and elbows. I doubt anyone would do this for long.) I'm not a physicist, but even on its face, this seems like it would require more energy. You can swim just as fast because you can *push harder* to overcome more drag. Pushing harder by definition means more force. What you should test is how long can a battery powered device continue to propel the craft in the more viscous fluid versus in water. I suspect it would last fractionally as long in the syrup. Probably half as long for a liquid that's twice as viscous, but it probably also relates to what the average output of the motor is.
I thought about this for a minute, but in truth, what's happening isn't that the turtle is pushing harder. If the turtle had to push harder, and thus use more power, in order to be able to make it through the syrup at the same speed, it would have been slower in this video. This is due to the fact it has the exact same motor as the other toy and uses the same motor whether in water or syrup, and no matter what always uses the same amount of power, unlike a human. If the turtle were using for example 10W of power to get across the water, it wouldn't suddenly start pulling 20W of power to get across the syrup at the same speed. It would still be using the same motor at the same power, meaning that if it truly needed more power to keep its pace then it wouldn't be keeping pace with the toy in the water in the first place. What's happening, as he said, is simply that each stroke the toy takes with the power it would be using in water should be slowed down by the syrup's viscosity, but is instead counteracted by how far the turtle gets pushed due to how easy it is to propel itself through the syrup comparative to water. Using the same amount of force, it is able to push itself further, but also is slowed down by viscosity, meaning it ultimately ends up the same speed and the same amount of energy used.
@@CyberCactus i thought of this too, but this is a matter of two things here: torque and maximum speed. the torque of the motor is enough to keep the flaps spinning at max speed in the syrup as in water, and since the maximum speed of the motor is the same in both liquids, there is no difference. (It probably also consume more energy, but im not really sure about that, im not very literate in electronics.) If the motor was not as powerful, you would indeed see the difference in speed, as it would slow down in syrup. in fact it actually did, in the more viscous liquid. the motor's torque was overmatched by the viscosity, as it could barely move its flaps.
@@StickyIckyOOHWAY Well if the toy was merely able to keep itself at max speed in the syrup, but had to pull more power to be able to do so, then it would logically have to be pulling less power from its motor to go the same speed in the water. This would require some kind of cap or limiter to be in place preventing the toy from pushing its little paddles harder than it does while it's in water. Otherwise, it would always use the same power and the same expended energy across liquids. I doubt the little toys he used in the video had any limiter that prevented them from putting the same amount of power into the water as they did into the syrup, and without limitations in water the max speed simply would have been *higher* in the water than it would in the syrup if the syrup were requiring more energy to wade through, due to the paddles having the same power from the motor which results in an easier time moving the paddles in the first place. I agree that the motor's lack of torque was a major contributor in why it wasn't able to move through the much more viscous liquid at the end. These fluid dynamics are strange but it seems there is simply a point in viscosity in which things stop moving easily, but until that point everything moves the same, like he went over at the end of the video. I'd love to see more demonstrations of the experiments so I can actually understand it better, at the moment admittedly I'm just theorising. You could absolutely be right and I'm missing something but so far I'm still convinced about my energy argument.

I love that you switched the turtle toys between the first and second swim tests. That eliminates any possibility of power differences changing the results.
A lot of this depends on how the speed of the "motor" varies with the drag. In your last example the paddle-arms were barely moving at all so of course it went slow. What would the results be if the turtle were designed so the arms moved at the same speed regardless of load? One difference between the experiment in the paper and your tests is that the guar gum has little effect on the density of the water, whereas the syrup you used would substantially increase the density, and so the swimmer/turtle would float higher in the fluid, which would in turn have an (undetermined) effect on the speed. The reduced cross-sectional area and the higher viscosity would have opposite effects on the form drag and it is not clear which effect would be stronger. Floating higher could also affect how well the driving surfaces (turtle's paddles, swimmer's arms and legs) engage with the water. In any case, swimming at the same speed in a more viscous fluid would definitely require more work and be more tiring.
But does syrup increase the energy per stroke? It's almost like a gear reduction. The lower the ratio, the more torque you have. Thus less energy needed per turn. Syrup is like this case but the opposite. Need explanation. Halp
Syrup with not require more energy per stroke... Because if u think about it the speed of movement is the same in both liquids... If it required more energy per stroke then there would have been a reduction in speed as well
If more energy was required then u would have to stroke faster to keep up with the speed in water.... But in the case of the toys shown, the speed of stroking was the same as well as the displacement of the toys
I was one of the "professional" swimmers that participated in this study. It was pretty wild. The guar gum liquid wasn't sticky, more slimy. There was a big layer of it at the bottom because it was hard to keep it in suspension, as the pumps created turbulence that would have altered the results.
@@Matthewsala they were closely monitoring the viscosity of the upper portion of the pool in which we were swimming, so I'm sure they achieved the desired test conditions (to whatever extent it could be expected). The bottom of the pool however, was a gloriously disgusting mass of about 3-6 inches of goo, with a consistency somewhere between papier mache paste and wet boogers.
@@robmangeri777 less than I would have thought. Hard to ignore the squish of the guard gum that settled to bottom of the pool between your toes though!
@@stinksorstonks1498 you can literally just look up "mythbusters swimming in syrup" and you find clips from the episode but here you go ua-cam.com/video/ub82Xb1C8os/v-deo.html
I've wondered about this actually. Because for very small scale insects and bacteria water and even air are thick and viscous by comparison. But they still manage to swim/fly around just fine. But they do it with different means. The smallest insect is called a fairy fly and it has wings that look more like long arms that it uses to literally crawl thru the air. So this answered why it still works.
I'd say no as the turtle traveled at the same speed. If pushing was harder (and therefore more tyring) it would have gone slower as it can only push at one speed.
There’s an optimal viscosity that allows more of your limb energy to transfer into forward movement. Each person's own swimming strength would determine how viscous that is.
@@beady0081 I assume it would matter how viscous the fluid was. The turtle in pure syrup didn’t produce enough force to move through it hardly at all, but I wonder how a human would faire? The turtle is obviously a mechanical toy meant to move through water. A human can adapt. Maybe swimming normally through pure syrup doesn’t work as well but you can adjust your technique to compensate in some other way. Who knows. I don’t think humans are going to value swimming through syrup enough to master the art lol
There is a sweet spot where all times are the same. If too viscous though it would be slow and unable to move, and if too thin, it also would be slow. Like if you were trying to swim in some material that was too thin you would hardly have anything to push off of.
You should retry the experiment with ether or acetone, or some other very low viscosity liquid, to see if something four times less viscous than water has an inverse effect or not.
I thought so too, but you would probably want to use ethanol or methanol, because acetone would do bad things to the plastic, and ether vapor would do bad things to you (as well as ignite on the slightest excuse).
Me: “let’s read some comments” Comments: “did anyone else think he was gonna swim in syrup?” “I clicked on this thinking he was gonna swim in syrup” “I wish he had have actually swum in syrup”
I’d be interested to see, what if you filled the middle of the container with water, and the outer edges with syrup, how fast would the turtle be then, having the syrup to propel itself and the low viscosity of the water to swim in. If that makes sense 🤔
The turtle also took longer in the thick syrup because its movement range is just rotating and the shape of the wing is a spoon, so it had a hardtime rotating under the syrup
itd be interesting to hear what the swimmers commented on the tests, even though they swam at roughly the same speed did they feel a higher difficulty trying to move through the syrup or did they feel their kicks would push them forward for farther? how much energy did they need to move the same amount within the same speed, was it harder or easier? did their efficiency increase ? decrease?
We didn't swim long enough to really tire out, and we rested a lot between repeats. Also, we randomly switched between the thickened and control pools to make sure cumulative fatigue wouldn't be an issue.
I gotta assume to some degree what we're seeing in the extra thick syrup is more about the energy output to push through the syrup and even break the surface tension is much higher, where the energy required for lower viscosity is more negligible at smaller distances. So, for the same energy output you could very much go the same speeds in thicker liquids, but water you could go furthest, same amount of energy expenditure would get you less far at the same speed in syrup, and even less distance the thicker the liquid is.

The reduced cross-sectional area and the higher viscosity would have opposite effects on the form drag and it is not clear which effect would be stronger. Floating higher could also affect how well the driving surfaces (turtle's paddles, swimmer's arms and legs) engage with the water.
In any case, swimming at the same speed in a more viscous fluid would definitely require more work and be more tiring.

But does syrup increase the energy per stroke? It's almost like a gear reduction. The lower the ratio, the more torque you have. Thus less energy needed per turn. Syrup is like this case but the opposite. Need explanation. Halp
My iq is not so high
@@Ryannn1212 it's not your iq is your knowledge
@@vittoriopaonessa bruh
Syrup with not require more energy per stroke... Because if u think about it the speed of movement is the same in both liquids... If it required more energy per stroke then there would have been a reduction in speed as well
If more energy was required then u would have to stroke faster to keep up with the speed in water.... But in the case of the toys shown, the speed of stroking was the same as well as the displacement of the toys

Related to this is the thixotropic properties of some viscous liquid. The stress or agitation applied to a viscous liquid may increase fluidity.
Loved it!!

I thought he would actually swim in syrup
Imagine opening your eyes undersyrup...
At least it would be balanced with accidentally swallowing the pool syrup
What if they pee in the pool tho
Actually would the pee rise to the top layer since the syrup is a denser liquid so when you swim at the top its though the pee layer nasty
I hate all 3 of you equally right now
Your welcome
@Somebritishguy™ You oof
i needed to see your surrup swimming pool
Your shirt cracks me up! 😂
I was one of the "professional" swimmers that participated in this study. It was pretty wild.
The guar gum liquid wasn't sticky, more slimy. There was a big layer of it at the bottom because it was hard to keep it in suspension, as the pumps created turbulence that would have altered the results.
So did the settling out affect the viscosity? Was it actually thinner in the part you swam in?
@@Matthewsala they were closely monitoring the viscosity of the upper portion of the pool in which we were swimming, so I'm sure they achieved the desired test conditions (to whatever extent it could be expected).
The bottom of the pool however, was a gloriously disgusting mass of about 3-6 inches of goo, with a consistency somewhere between papier mache paste and wet boogers.
That’s a pretty cool experience! Did it feel any different other than the sliminess?
Guar gum is one of those things that sound fun to play with, but as soon as you actually do it's just a disgusting mess.
@@robmangeri777 less than I would have thought. Hard to ignore the squish of the guard gum that settled to bottom of the pool between your toes though!

I've wondered about this actually. Because for very small scale insects and bacteria water and even air are thick and viscous by comparison. But they still manage to swim/fly around just fine. But they do it with different means. The smallest insect is called a fairy fly and it has wings that look more like long arms that it uses to literally crawl thru the air. So this answered why it still works.
A splendid presentation.

On the long run would it make the swimmer more tired to swim in a more viscous liquid or not
I'd say no as the turtle traveled at the same speed. If pushing was harder (and therefore more tyring) it would have gone slower as it can only push at one speed.
There’s an optimal viscosity that allows more of your limb energy to transfer into forward movement. Each person's own swimming strength would determine how viscous that is.
@@beady0081
I assume it would matter how viscous the fluid was.
The turtle in pure syrup didn’t produce enough force to move through it hardly at all, but I wonder how a human would faire?
The turtle is obviously a mechanical toy meant to move through water. A human can adapt. Maybe swimming normally through pure syrup doesn’t work as well but you can adjust your technique to compensate in some other way. Who knows. I don’t think humans are going to value swimming through syrup enough to master the art lol
I for sure though I was going to get to see a human being doing laps in syrup. First time I've ever been disappointed by this channel 🤣
I thought he would swim in syrup , as I saw the thumbnail😂

XD

There is a sweet spot where all times are the same. If too viscous though it would be slow and unable to move, and if too thin, it also would be slow. Like if you were trying to swim in some material that was too thin you would hardly have anything to push off of.
Your shirt is making me constantly think my screen is loading lol
You should retry the experiment with ether or acetone, or some other very low viscosity liquid, to see if something four times less viscous than water has an inverse effect or not.
I was thinking about that too, if that is the case, then I'd be interesting to see what the "ideal" amount of viscosity would be for humans.
I thought so too, but you would probably want to use ethanol or methanol, because acetone would do bad things to the plastic, and ether vapor would do bad things to you (as well as ignite on the slightest excuse).
@@Lucius_Chiaraviglio you can also use a container with a different material

I do be wishing that he swam in da syrup tho
Yup,metoo
“swum”
@@mayam3072 what?
I’d be interested to see, what if you filled the middle of the container with water, and the outer edges with syrup, how fast would the turtle be then, having the syrup to propel itself and the low viscosity of the water to swim in. If that makes sense 🤔
It might be slower in the thick syrup @5:28, but the arms rotate about the same number of times. About 6 or 7 to get half way across the tub.
I thought he was actually going to swim in syrup but then i got Jebaited so damn hard
Right 😔

Guys, we need mr beast to actualy do this with a real pool
I agree
Mythbusters did already tho years ago.
These turtles combined with that paddling sound is just so adorable
Do a full-scale test!
Me watching this while not having syrup in my country so i always have to import: *intense screaming and crying*
2:05 When you hit shift to start a word, but have caps lock on
I loved when The Mythbusters did this
The turtle also took longer in the thick syrup because its movement range is just rotating and the shape of the wing is a spoon, so it had a hardtime rotating under the syrup
I'm surprised you didn't mention how the density change would lift more of the swimmer out. I would think that would decrease drag a lot?
Everybody: he had us in the whole video ngl
A straw....in a turtle...
Well isn’t that ironic
stop
itd be interesting to hear what the swimmers commented on the tests, even though they swam at roughly the same speed did they feel a higher difficulty trying to move through the syrup or did they feel their kicks would push them forward for farther? how much energy did they need to move the same amount within the same speed, was it harder or easier? did their efficiency increase ? decrease?
Ur shirt was trippy lmao i thought the video was buffering
I'm curious about the university experiment - did the swimmers tire out more quickly in the syrup than water?
Probably yes. But they were professionals so they managed to do it in time
How does one get tired swimming in sugar?
@@moonlight5889 They also timed lay swimmers.
We didn't swim long enough to really tire out, and we rested a lot between repeats. Also, we randomly switched between the thickened and control pools to make sure cumulative fatigue wouldn't be an issue.
Ha - hey Brian, been a long time!
I'll second what he said, it really wasn't tiring - swims were too short with too much rest in between to get tired.
“Sirup” Idk why that annoyed me so much 😂

this is awsome bro i will past my test bro
I gotta assume to some degree what we're seeing in the extra thick syrup is more about the energy output to push through the syrup and even break the surface tension is much higher, where the energy required for lower viscosity is more negligible at smaller distances. So, for the same energy output you could very much go the same speeds in thicker liquids, but water you could go furthest, same amount of energy expenditure would get you less far at the same speed in syrup, and even less distance the thicker the liquid is.
My physics and swimming teacher needs to see this
