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!

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.

[@rxotmfrxotmf8208]

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.

[@galgrunfeld9954]

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?

[@stevecollins2770]

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.

[@johnm5928]

Objects in orbit are under constant acceleration.

[@zapperone7]

John M I think he means when experiencing microgravity

[@MEBVishwaS]

Yes objects in circles experience acceleration but that acceleration is canceled by downward gravitational force. Hence net acceleration is zero, object experience 0g.

[@johnm5928]

@@MEBVishwaS Objects in orbit are constantly accelerating at a rate of 9.8m/s^2. Objects in orbit are in free fall, which is constant acceleration.

[@stevecollins2770]

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.

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?🤔

[@ninjaturtletyke3328]

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

[@mistersaur]

[@MrTrevortxeartxe]

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.

Slight correction, you used centripetal force and centrifugal force kinda interchangeably, which isn't right. Centripetal and centrifugal forces are forced that act counter to one another to maintain a body rotating around a point. They're best conceptualized by thinking of a weight tied to a string being swung around in a circle. Centrifugal force is the mass of the weight pulling outward on the string, the centripetal force is the string pulling the weight back towards the center of rotation.

Now here’s an other experiment. Rotate a bicycle wheel and drop it. Have it dropped when it’s vertical, horizontal and on it’s diagonal. When dropped on its vertical axis, what will happen? Will the rotational force increase, decrease or stay the same? Will the wheel drop faster or slow as compared to it not spinning at all? Same goes with horizontal and diagonally. In either case, will the axis change? Meaning if dropped horizontally, will the wheel try to go into the vertical or the other way around?

I have no idea what did u Said

The Action Lab, how do capillary forces interact? Are they so small that they are negligible compared to gravitational and rotational forces?

He always looks back and forth to make sure you’re paying attention

Once my father SHOCKED me hard...Static electrically!...We went for a tour in the Himalayas...Temperature was really cold and below freezing point...I was organizing the Fluffy blankets...anyhow I touched my fathers beard...and heard a cracking sound...And got a high shock in my finger!...the experience was really good!

I like the whirlpool one, but even better: When released, the water didn't just become a cylinder, it actually jumped to the top of the bottle, which suggests that the force of the spinning water on the inside of the bottle actually shoved the bottle down faster than gravity, which wouldn't last long, but makes sense in the sort of two-body system that dropping it created.

Your videos really make my day❤️

This is the best way to learn cause I am actually interested unlike in class it's just a the hardest content to make and you are doing it good

[@marcofrancioni1155]

I would like to see the drop of the whirlpool when the bottle is almost empty! I want to see if keeping the swirl along the walls and letting it to resume at the end of the fall!

I was thinking if we had an anti-gravity device we could have destroyed hurricanes by turning a giant one of them in the middle of it so that the cloud would splatter to the sides. :D The video was very interesting!
