Awesome!
Thanks for teaching me sth new today
Could you make a video on elon musk's starlink project????👍👍
What should I do to get a vacuum humber???!!!
I meant vacuum chamber
Brilliant use of pressure differentials. After this video, the chore of vacuuming will forever be fun.
Hey checkmark

Hello u have been watching him lately
I live in Karachi Pakistan and I like your comment
@@sarapadeti1125 I live in Karachi Pakistan and I like your comment if you don't mind
No officer, I wasn’t littering…. I was just vacuuming my car

Hehe hahaha

" so lets see if they get sucked in "
As an aerospace engineer, I wish I had gotten this intuitive explanation of the Bernoulli's equation way back in school..it would have made the road ahead so much easier!
Too bad the road ahead is now littered with styrofoam.
@@Chris.Pontius
Littered? It's a Styrofoam carpet!
I wouldn´t have believed you if you hadn't said you were an aerospace engineer.
One question, why does this easy explanation hold, if you can derive it with the conservation of energy and not with statistics?
Why can you explain the functioning of airplanes with bernoullies principle, but also with newton (air will get pushed downwards so the plane will go up or lower pressure due to the roundness of the wing)? normally when there are two explanations they fit into each other and you've got a overall understanding of the problem if you know both explanations, but in this case of bernoulli, it confuses me.
@@neutronenstern. " but in this case of bernoulli, it confuses me." Berboulli's principle can't explain why a leaf, a plastic bag, or an upside down aircraft can fly in the air or wind.
5:20 "So, what this means now is that I'm getting pulled over for littering." lol
wow this is the best and most intuitive explanation of bernoulli 's equation ! took thermodynamics and fluid dynamics module in uni and the professors never explained as elegant as you do!
agreed for years i knew the principle but i never really understood why the stuff in the pipe "had to" be faster and low pressure, but today i have finally learned
This is why I watch his channel. I had the same issue.
Why do youtube videos always do a better job of explaining things than college professors? 😂
yup me too, I also took fluid dynamic but The Action Lab explaining about venturi effect in 8 minutes better than my lecturer in 2 hours class lol
@@christopherpape4823 one reason maybe that you watch these voluntarily with an open mind at times you choose. Also, he chooses topics which he can explain well and entertaining. With a lecture series or a curriculum the choice is limited or non existent.
Action lab: how to litter in a more interesting way when driving down the highway.
Exactly. He's a litterbug.
I bet they are cellulose packing balls but they are usually in a large pill shape so idk
But i was just cleaning my car whatcha mean littering
*@The Action Lab*
3:00 You also have centrifugal forces too on every air molecule in the spinning part of the tube, that also makes the air move outwards.
Technically yeah but air molecules move at hundreds of miles an hour so it doesn't affect it enough to make a difference
@@boopnose5503 not with that attitude
@@chapstickbomber whaaaaaaa
I thought of that as well, there a pumps that work mainly with this principle.
Yes. I also think that his relative speed approach doesn't work in the first example, as the air in the tube is constantly accelerating 🤔
Next time on action labs: I was arrested for speeding and littering.
🎶 .... Bad boys... Bad boys .... Whatcha gonna dooo??? 🎶
Also vacuuming while driving
The little fun clips and his facial expressions make it more fun than just watching science in action
Leave everything just look at the joy on his face 😁
😁
He's always like that 😆
That's exactly why I love his videos. He seems to genuinely be enjoying the science experiments he is doing, and his joy just make me happier
Well, he IS playing with a self sucking hose...

Thanks for the intuitive explanation. I’ve always struggled with understanding how what causes Bernoulli’s principle to work.

"So what this means now is..."
You just polluted the road there's nothing else to say 😂
1:39 I am pretty sure this is how traditional siphon feed paint guns work. Awesome job.
A clever way to publicly litter from my car. Thanks! 😅
7:40 what an explanation, actually all of your explanations are so good,i would grasp everything if you were my physics teacher
I have a joke. But the channel is too wholesome for it 🤣.
you mean the one with the hose and the balls at the end of it? tell it pls.
@@GodTaoo I assume it's at 4:49
“This machine has many many uses, even for times you’re a little… more lonely” is that what you were thinking xd
Littering isn't wholesome.
- Honey, we need a vacuum cleaner.
- We've got a vacuum cleaner at home.
Vacuum cleaner at home:
Did you pick up any styro ball you blow outside or did you left them in nature.
It is one of very few materials that NEVER ever never, decomposes. While it may take a plastic bottle 450 years to decompose and a glass bottle 1 million, Styrofoam stays strong and doesn't give in to the elements of nature, ever
They were tiny little pieces
But pieces nonetheless
Literally what i thought
Don't think he's going to save any turtles 🐢
They do decompose over time. May not be scientifically proven, but have you ever left a hard styrofoam box outside for a few years and gone back to it thinking "it's ok, it'll still be good" go to pick it up and it literally crumbles in your hands. I have, so either I'm really strong, or styrofoam decomposes over time.
Me: "I'm mature now"
Also me: 4:49 "Balls hehe"
2:09 HEY that's how a carburetor works on an engine!! So cool to see it from this perspective!
4:47 I LAUGHED SO HARD MY THROAT HURTS
U mean because he says "and then on this end I have my balls." ?? LOL ok I'll admit it me too.
Why is everyone sleeping on this one 😂😂😂😂
0:35 what an incredible way to clean the house 😂
Ah yes, the floor here was and is and will stay made Outta garbage
This video probably increased the vaccum-related car accidents
YES! First video of him where i actually knew how to do this without ever having done it before. I feel smart :D
I guess another example of Bernouli's principle is having a strip of paper, holding it at the narrow end and blowing over it. The end of the paper lifts up.
Well done, keep it up!
I studied about Bernoulli's Principle 7-10 months ago. But this is gold. I understand principle much better in this video.
So... we need a new slogan now! "Don't Vacuum and Drive" kids!
4:45 omg don’t close your eyes when you listen to this 😭
this guy can explain even quantum mechanics with the ease of explaining the alphabet
LoL this is hardly quantum physics. It’s basic kinetics. Newtonian physics is enough to explain all of it.
@@petergoestohollywood382 I am not telling you about this specific video .....
I am just talking about how this guy explains everything easily even to guys like you
Self sucking? If only all of us were as lucky as that vacuum
Are we just going to ignore the huge impact the centrifugal force had on the first experiment?
This! I would imagine all the air trying to move from the center to the edge die to the spinning is the main reason it's sucking.
Yes, that‘s exactly what I meant. The air trying to move to the edge/top of the tube creates lower preasure in the center/middle of the tube. This would also explain, why it worked so well in the beginning, compared to the first attempt in the car at lower speed.
Air molecules move at hundreds of miles an hour. To create a huge impact you'd need to spin the tube at way higher speeds.
"Air" molecules move at at 330~ m/s so he isnt spinning fast enough for that
An eight minute video can teach you more than 80 minute of class at school. Great job
QUESTION: with the spinning tube, is the pressure reduction *solely* due to Bernoulli's principle, or is there also a component that is due to centrifugal force moving the air out of the tube?
4:46 Damn you are wild man
The Physics Teacher We Want ❤️❤️
He is a chemical engineer, watch physics wallah
I first saw this explanation of Bernoulli’s principle in a video of Eugene Khutoryansky. It completely blew my mind. I’m glad you also went with this approach. It makes so much more sense this way. Usually physics teacher’s explanations on this are kinda incomplete. Thanks for bringing it to a wider audience :)
Perfectly explained with magnets. Excellent video!
The best explanation I have ever seen of why area is inversely related to pressure!
Wait don’t pollute with the styrofoam 😭
I hope to become an aerospace engineer in future and principals like this intrigued me I have learnt much from the books but this was the best visual representation.
Am I the only one concerned about the fact that he's littering? I mean, yea sure the self vacuum is cool but not when you start shooting out trash on the road.
No I was concerned about it too, technically he could be fined.
agreed. It would have been easy enough to find something that isn't trash (light seeds like dandelion seeds, bits of dead leaves, etc) to use instead of styrofoam.
Me too
Im assuming he had some way to catch them on the other end, he seems like too good of a dude to just litter like that.
shit the styrofoam came from the earth
_casually litters the streets in the name of science_
5:23 it doesn't matter if your car's inside is clean or not if you crash it... 😂
Using the science of magnetism to demonstrate how Bernoulli’s principle works…a true science nerd…love it!!! Great video 👍
Is it Bernoulli though? Or are you just throwing the air from the tube (when spinning it) and thus decreasing the pressure inside?
I think it is both. It certainly is Bernoulli, but you are also throwing mass (the air) out of the tube. If the tube was filled with golf balls, they would be thrown out too.
I think if it was just throwing the air from the tube, the effect would only last as long as there was air in the tube to move. So if it was just the air being thrown out, I would assume the effect would only last a second or two. Since the effects continue as long as you spin the tube, that looks more like Bernoulli's to me
@@Loganxmusic9339 The air being "thrown" out also "pulls" air from the bottom
@@Astromath and that's Bernoulli's principle
The conservation of angular momentum is not the same as Bernoulli's Principle. The Torque is doing most of the work and the cup proves it. The small holes are restricting way to much airflow especially when you consider how unevenly and turbulent the flow would be on the rotating section.
Turbulence is the enemy of Bernoulli's Principle. He is acting as a blower fan. When hes in the car, it is Bernoulli's Principle though.
Awesome now I can vacuum while I’m driving :-)
This can honestly be useful if you have to clean up something and you have a tube like that
But it’ll make you look like your clinically insane lol
A small price to pay for a slightly cleaner room
My stupid self would use it, but forget to cover the end and spit the dirt everywhere again.
Breaking all stuff around in your room, it's not useful even outside
I think there's a secondary component to twirling the hose that you might have missed. At that point I think it acts like a centrifugal pump and the inertia that you're creating in the air in the hose flings it out of the end also creating a low pressure behind it in the hose.
I made my own vacuum out of a hand pump and some silicone lips i had laying around
Cleans Dust pretty good
This video is priceless, now i understand why there is actually lower presure inside the narrower tube
That was a REALLY good explanation on how it works.
Wife: Husband, can we have a vacum cleaner?
Husband: we have a vacum cleaner at home
Vacum cleaner at home:
In Bernoulli's principal, we assume that the liquid follows streamlines. So how can we say that the reason for the pressure difference is the random collisions of liquid atoms???
Still works. It’s how hoses increase their spray.
@@westonding8953 Yes, it does but the explanation is not valid, is it?
@@_seniru_dilmith_ I don’t see why it isn’t? The liquid molecules still randomly.
@@justSomeOrdinaryPerson I'm completely agree with you!
This channel is “SO MUCH FUN!”👍🤓😵💫😎
Wonder how long it took to pick up all them foam balls from the road.😉
Those are very child friendly experiments!
They'll inspire new generations of scientists and engineers!
And me :)
Keep up your amazing work!
Do not clean your car with the method shown in the video. That's throwing the trash outside your car and on the ground. That's littering.
That's what I was thinking lol. Better have a mesh or something to catch whatever gets sucked up.
Only if there's trash in your car. If it's just dirt, leaves, and dust it's OK.
@@idahogie just like the styrofoam balls and gum wrapper in his car...
Lol
Yeah it won't be as effective but there really should be a filter on that
We use this concept in the natural gas industry when trying to pinpoint a leak (gas migrates underground, so higher gas readings in one spot doesn’t always mean you’ve found the leak). We use a purger, which is simply a Venturi that sets atop a 3’ aluminum tube with several holes at the bottom. When compressed air is pushed through the purger, from back to front, it creates the low pressure area where the restriction is inside. This creates the vacuum in the aluminum pipe and sucks methane from the surrounding soil. Once the soil is mostly clear, you can begin testing different spots to see where the highest readings are, and there is your leak.
I think you are describibng an ejector pump which operastes by entrainment, not by the improper interpretation of Bernoulli's Principle.
@@Observ45er no, I’m not. It’s a Venturi, with no moving parts. It uses the effect noted in the video to create vacuum.
@@skoalsoldier Ok. So reading it again carefully, I see it's a pipe that shrinks in diameter, but then has holes to the outside pipe that is around in the narrow section. Then, I guess, the aluminum pipe is used like a vacuum cleaner hose?
Is that a correct interpretation?
Kinda disappointed you polluted the sidewalk with plastic. Just use my biodegradable shredded report card from last year dude.
Another reason why this vacuum non-machine works, and possibly the reason why it works better than the hose in the car's window, is that by spinning the hose like that you are centrifuging the air away radially. This is actually how the pump in a vacuum cleaner creates the vacuum. It is a similar effect to this experiment: Have a heavier and a lighter stone connected by a string passing through a tube. Put the tube vertical with the 2 stones hanging from the string and the string will slide through the tube such as the heavier stone will go down and the lighter stone will go up. now let the heavier stone hanging and spin the lighter stone above your head and the lighter stone, as it is centrifuged away, will lift the heavier stone.
"Just look in the joy in my face"
While a bunch of white stuff comes out of a tube
Alright buddy, calm down 😂😆😂
Following a self-sucking sesh
He gets to play with a self sucking hose... Hope his wife don't catch him...
underrated
he he he sugma balls he he he
Actually there's a centrifugal effect forcing the column of air in the spinning region of the tube out the end creating inward pressure at the end by the table, in addition Bernoulli's principle. He had to drive quite a bit faster than he manually rotated the tube above his head to achieve comparable suction.
No, he was spinning the tube about 80 rpm, @ 3 ft. radius thats around 50 mph.
which is about the speed of the car sounded like.
@@mrbmp09 @0:20 shows the tube extend from his hand to head, so there's no more than 1.5ft rotating, and I'll even give you 120rpm, which still only comes out to 12.85mph:
2 × 3.14159 × 1.5ft × 120rpm × 60min/hr ÷ 5280 ft/mi = 12.85mph
At the end he should have added "order now and you will get another vaccum pipe for free!!"
Never thought I'd watch any video titled "self sucking" so casually

Officer: I caught you littering from your vehicle, that's going to be a $1000 fine.
This guy: Sorry officer I was just vacuuming my car.
Ah yes, enslaved succ
Brilliant use of the Venturi and Explaning the Bernoulli’s Principle, showed it to my student pilots!
I partially disagree. I strongly believe that the phenomena shown during rotation is due to centripetal force acting on the air inside pushing it out and thus creating a low pressure.
I agree to the fact that most other stuffs shown in the video are due to Bernoulli's principle.
Feel free to put your comments below (anyone). Happy to learn.
Agreed. While Bernoulli’s principle is responsible for a fraction of the suction when he is rotating the tube, the majority of the suction is likely coming from the centrifuge effect. In essence, he created a single vane centrifugal compressor. Good explanation of BP, but partially misleading, at least when explains the rotating of the hose.
It would be interesting to know the tip velocity achieved by hand vs in car.
Also in the car, having the window open changes the pressure in the cabin. Would be a more reliable experiment using some sort of wind tunnel.
It's a matter to gain some air velocity, he just make circles with the pipe, and as he already proven in the car, it happens the same when going at a straight line, so centripetal force has nothing to do about it. Also when pushing air with the syringe, there's zero centripetal force, it happens the same thing (that one principle is a variant of Bernoulli actually, called Venturi effect, used in carburetors) He's actually creating the low pressure by velocity, that's the Bernoulli Principle at its best.
@@jimmytvfclassic partially correct. Some of the suction is due to that, but most force is happening from centrifugal motion (not “centripetal” acceleration). Check out how a centrifugal pump or centrifugal compressor works. He effectively made a centrifugal compressor or blower.
A small correction as John pointed out. Centrifugal force not centripetal force.
My dad used the same law to suck out water out of the water tank
4:45 can we just appreciate how this guys risking his life for the littering fine just to show it for our knowledge? '-')/
That is how car's crankcase ventilation systems use to work. The vent tubes would stick out into the airstream (under the car). The end of the tube was not square though, they were cut at an angle, so the opening was on the downwind side.
It’s pretty stupid to throw those little styrofoam balls out the window into the bushes, next time you need to throw stuff out, use seeds instead idk
"Sir do you know why I pulled you over?"
"...umm....because I was teaching science?"
Uhhh interesting title lmao
i just learned how a carburetor works not long ago, so it was cool to recognize the similarity in the in the aspirator and a carburetor
Hear me out…
@ 2:00 this is how a carburetor works, and this is one of the best simple, but still incredibly accurate, and understandable demonstrations I have seen. This one made it really click for me
And it was a fantastic demonstration of how air velocity affects the effect of Bernoulli
"Vacuum while you driving", throwing garbage into the street. Not that nice 😅
You had me at self-sucking.
Man, you have really talent of explaining physics phenomena without using advanced math. If children have been learned this way we would get to the stars much faster. Thanks.
Top tip: if transporting an aged relative who might be covid positive, use a nose mask with a tube out the window. The negative pressure keeps the mask clamped to your face, thus blocking off nasal receptors, yet you can still breathe fresh air easily. Sounds a little nuts, but I used this successfully back in March '20... Just saying. Old UK duffer here :)
the aspirator was used in the milllikan oil drop experiment too. very cool
I think you also have a function of centripetal force aiding your vacuum as well. I bet if you completely plugged the end and spun it like that with a pressure sensor in the end you would be able to show an increase in pressure at the tip of the vacuum without the air movement. This is why I performing the same type of action with a hose filled with water also works.
Wow. This was the clearest explanation of Bernoulli's principle I've ever heard.
Smart move, not showing the Styrofoam balls getting sprayed out of the car....🤐!
Great presentation, but I think you should have brought up common real life scenarios that the Bernoulli's principle is used in, such as carburetors and liquid miracle grow spray nozzles for garden hoses. Seeing real life applications can help drive the idea home with some.
0:34 his sad face literally looked joyful for the first time
His face was overflowing with joy.
I wouldn't have believed it's due to pressure difference, unless you drove the car. Great experiment
This guy is actually like our personal school teacher. I love it
The teacher to me:- Get out of the class
My friends:- 0:36
Police: Why you over speed?
Guy: i was just cleaning my car.
That is exactly how a venturi on a carburetor works. I believe that you use the bernoullis principle to calculate the venturi effect rate.
