I don't know how you do it. I'm 37 years old and have been into science my whole life but you always find new ways to amaze me. You're truly an invaluable contribution to the world.
Really great experiments! What I realized in the 0g whirls experiment is that the whirls collapsed shortly before reaching the ground. If the drop of the bottle was longer, I guess this would be also pretty interesting to see. I think this is due to lack of gravity which is the driving force to build the vortex in the first place. The vortex only exists, because water from the upper bottle wants to go down to the lower bottle. Without gravity, the water doesn't move down anymore. As a result, the only movement should be caused by the centripetal force and by getting "reflected" by the bottle's wall. I really would love the see that happening!
Learning for the sake of learning is useless though. Like, what would you use the information to do? Pursue a career in science and actually change lives? Start a youtube channel? Write a book? Like why spend your life learning facts that you don't actually use to bring value (eg money) to yourself and others? What's the point?

And this may could be the topic of a new video, like showing how can we create artificial gravity in space, by spinning a 'spacecity' or anything around its own axis, (if it is possible).
I've already watched a youtube video about it (if I'm not mistaken, by PBS Space-Time). It's not as simple as snipping a spaceship. It needs to have a very big radius, otherwise, you would get some uncomfortable Coriolis effect when getting up (your head would feel a force to a side). Also, jumping would sort of break the system. You might think these are only concerns, not features that make a spinning city impractical, but it's definitely important to consider. Maybe training the astronauts would be enough and they would get used to the weird perks
That’s a very well done empiric science video. Bravo! I’d like to add that due to the greater upward pressure, bubbles tend to get a thick “contact lens” shape (concave on the bottom and convex on the top) instead of a sphere. They’re full of unstable turbulences. Inversely, we can see how much it tend to be become more smooth and spherical in the ISS or your world shots.
Yeah! I thought so too, until I realized this is also how Zero-G planes work, after they finish accelerating upwards they cut the engines and go freefall, making the objects (and humans) inside go Zero G.
This really amazed me. I didn't think the accelerometer would show 0g as soon as it left your hands. I thought it would start showing 0 once it reached the peak of its trajectory.
Not really. It's not a new description. Same one we learned in school. I just disagree with the interpretations and don't beLIEve gravity is what they claim it is. They use terminology that, in the 'experts opinions' cannot and should not be questioned. Well that isn't what science is now ..is it!? For me gravity is on pending more evidence. But the globular earth and their claimed axial and orbital motions as well as it's alleged convexity, well, that has been falsified... Thoroughly, definitively, repeatedly. @The Action Lab I beg to differ sir; There is a difference between centrifugal and centripetal force. And it does NOT require a Spinny ball. It is in the magneto dielectric "fields" for lack of a better term. How do you explain the magnetic field on this alleged ball?

Hey, that whirlpool in 0g was interesting to me - I never thought about it. Can you think of some applications to it? Like togglable inner-layer coating? A contained dry zone? Something else?
When a rocket in outer space is not being accelerated (I.e., it is just in orbit or on it's way to Mars, etc.) the fuel and oxygen arrange themselves in a layer against the walls of the tank, like the whirlpool shown here. This poses a problem for pumping liquid out of the tank because the pumping will quickly form a cone "down" to the opening of the pipe that carries away the liquid. One way of overcoming this is to put a crease in the side of the tank. Surface tension then forces the liquid to move toward the crease where it can be pumped away. I've never seen this done, but is seems like you could make a creased pop bottle the the liquid would move into the crease as the bottle fell.
Yes objects in circles experience acceleration but that acceleration is canceled by downward gravitational force. Hence net acceleration is zero, object experience 0g.
Objects in orbit experience lots of acceleration. Sorry to cause confusion by not explaining clearly. Gravity will accelerate the object downward. In a circular orbit, momentum is resolved into a vector in the direction of travel and a direction outward from the center of the earth. If the object remains at a constant altitude, the gravity vector and outward vector are equal and "cancel" each other, making no net vertical acceleration. The vector in the direction of travel is unopposed, thus the object moves "foreward." If no additional force is applied, both the liquid and the tank will move at the same speed and surface tension can work its magic.
@@CypherDND yes i know...thats why i told them , they cant keep saying only density and buoyancy is what making things to go down and up..because for these phenomena to exist , there must be gravity...without gravity things should be in rest where it is...
@@kvsalahuddin5 Next time a flerfer tells you that gravity "doesn't exist" and that things fall to the ground "because of density", challenge him to calculate how long it would take for an object to free-fall from a known height (say 10 meters) using only the object's density (say 10g/cm³), *_not_* the acceleration of gravity. Then, watch him quietly go away. Density is not a force. Density does not cause movement.
Very good home videos, no gimmicks, and beautiful physics explained. Just a minor note... In free fall, the acceleration due to gravity in the water is zero, and there is no pressure at all no matter what the depth, so there is no force upwards or downwards on a bubble in the water. The bubble doesn't stay still because of equalized pressure, but because there is no pressure anywhere in the water.
And again a brilliant video. I am once more flabbergasted by the way of creative thinking to simulate "0" gravity. At last a "personal question": you are always in a good mood, laugh etc. I can't think of you being mad at something (see this as a compliment) 😉
Simply genius! I bet most educated in science or physics never realised this. This is because conventional education system does not teach us this. New knowledge are discovered and derived and not taught. This is why Education system is over-rated. Most teachers would not know this knowledge also.

That was an awesome answer toy question a while ago...so...the water at the top of the whirlpool is what empties out first through the drain, after travelling up the side of the container. Thank you so much for this demonstration!
If that same whirlpool bottle is thrown out if a plane, water will first form a cylinder and gradually get back to whirlpool shape again as it reaches terminal velocity, right?🤔
The bottle is being acted on by the water as well. I think you may have to assume the bottle remains fixed in its position. Because it can twist and the bottle will start rotating too. You can probably just flip the bottle over to simulate that. But that’s a lot of angular force against the water if you do it too quickly. So I would guess you want to do it slowly Edit: but maybe you want to turn it over quickly. I’m not certain. It’s harder for a vortex to rotate on its side. You are probably going to lose a lot of force no matter how you rotate it. Idk
Dad: WHAY ARE YOU DROPPING THOSE WATER BOTTLES? Me: I'm stirring the heroin mixture Dad: Don't lie you were watching those Action Lab videos again, weren't you? Me:
@@Owen_loves_Butters centripetal is the force carrying you toward the center of an arc. This would be the friction from tires on a car, or a string on a toy being swung in circles, or gravity from the sun keeping us in orbit Centrifugal is center fleeing. This is the inertia that pulls you the opposite direction in a turn, or keeps said toy string taut, or keeps earth from falling into the sun (its basically just inertia, and centripetal force is the acceleration to change direction)
It should be ZERO-g because capital G is the gravitation constant which equals 6.67 x 10^-11 m^3 kg−1 s^−2 and g is the acceleration due to gravity which equals 9.81 m s^-2. Nice Video!
inmagine having him as your teacher, like i would shut my mouth the entire time like actualy this is so interesting im watching this in my free time like you guys but this guy needs yo hear this!!!
Correction: Bubbles move in zero G of the water around is allowed to create surface tension, aaa I see where you put a space bubble. Look into further, i have videos of the bubbles moving :) Great video! Yes, finally!!!!
Another way to explain the whirlpool would be to say that with a water bottle in gravity, there's less pressure on the top than on the bottom. So when you introduce rotation into the water, centrifugal force pushes against the water, but the water on the bottom pushes back with more force due to more water pressure. The forces equal out, and a whirlpool is born, giving it its distinct tapered shape. But when there's no gravity, there's no gradient in water pressure, so the forces equal out by becoming straight.
Another reason for water sticking to sides; Water column's upper surface (membrane if u wanna call it). Always align itself perpendicular to the net force and here at 0g Only centrifugal force exists which pulls water outside of its axis.

You just solved world hunger.
Hell yeah now I won't be hungry at Matt's channel
Really good explanation. This guy is real genius, he explains to people like everybody is 5 years old
Excellent two person stunt!
you are one of the best teachers out there
your explaination are so clear, you should teach all the physic teachers
6:50 Centrifugal = "center fleeing"; centripetal = "center seeking"
One goes out, the other goes in. Theyre not the same. Cool video though!
@@avinavchalise6962 ok, but theyre defined terms so...
@@Owen_loves_Butters centripetal is the force carrying you toward the center of an arc. This would be the friction from tires on a car, or a string on a toy being swung in circles, or gravity from the sun keeping us in orbit
Centrifugal is center fleeing. This is the inertia that pulls you the opposite direction in a turn, or keeps said toy string taut, or keeps earth from falling into the sun (its basically just inertia, and centripetal force is the acceleration to change direction)
Damn, everyone of your videos deal with really interesting ideas it seems, I had no idea this channel was such a gem! :D
You just helped me solve a cosmic problem.. like seriously!
Here and Mind Field are two places I always watch for knowledge. Learning is fun and knowledge is power.
This adds to my idea of space being much like water and the difference between spacevortex and water vortex.
This was mind blowing at every sentence
Man! What a simple and great experiment!!!
I would never get the result!
Exactly what I expected but still not disappointed
Your videos really make my day❤️
This can do anything on the Earth 🌎.....🤘🏻🤘🏻🤘🏻A huge fan from India 🇮🇳🇮🇳🇮🇳
Not gonna lie
I thought this dude is gonna try a ZERO G airplane
But this guy impressed with his new idea
Oh that is the greatest video for educating flat-earthers. "There is no buoyancy without gravity"
Wow . I understand gravity more now. Thank you so much!
right after the bubbles, excellent!
It should be ZERO-g because capital G is the gravitation constant which equals 6.67 x 10^-11 m^3 kg−1 s^−2 and g is the acceleration due to gravity which equals 9.81 m s^-2.
Nice Video!
Best channel on UA-cam
This made today a good day
inmagine having him as your teacher, like i would shut my mouth the entire time like actualy this is so interesting im watching this in my free time like you guys but this guy needs yo hear this!!!
This guy can do anything.
Correction: Bubbles move in zero G of the water around is allowed to create surface tension, aaa I see where you put a space bubble. Look into further, i have videos of the bubbles moving :) Great video! Yes, finally!!!!
right after the explanation, bliss!!
Best chanel to watch science live experiment.
Another way to explain the whirlpool would be to say that with a water bottle in gravity, there's less pressure on the top than on the bottom. So when you introduce rotation into the water, centrifugal force pushes against the water, but the water on the bottom pushes back with more force due to more water pressure. The forces equal out, and a whirlpool is born, giving it its distinct tapered shape. But when there's no gravity, there's no gradient in water pressure, so the forces equal out by becoming straight.
Probably one of your best videos!
Thanks for the video!! I'm from Brazil and I was able to understand your explanation, it was very good!
Someone who has the right connections needs to get the folks in the ISS to try that whirlpool experiment and show us what happens!
Another reason for water sticking to sides;
Water column's upper surface (membrane if u wanna call it). Always align itself perpendicular to the net force and here at 0g
Only centrifugal force exists which pulls water outside of its axis.
I wish I had a science teacher like this growing up.
He always looks back and forth to make sure you’re paying attention
I learnt so much with this video!
I was just drawing the effects of pressure out yesterday! It makes a difference seeing it in action. Thanks for sharing.
