This is honestly one of the coolest experiments i didnt know i needed to see.

A question, why did the flask not explode as soon as you connected the long pipe ? Did you add a small amount of water at the top just before it exploded ? the video showed you filing the tube slowly discussing bubbles and bouncing etc, I'm just trying to understand when it was all connected ? great video and explanation.

Please, please come back, i know videos take a lot of work to produce with no tangible return for a while, but you're out here fhabging lives!! I was learning about fluid pressure when i found the channel almost a year ago and have loved fluid dynamics since!!

6:05 Why does it look so cute?? :')

Another pressure created by fluids creating pressure is the pressure felt when there is an upcoming exam about the pressure created by fluids creating pressure. (help)

India ❤

So 500 years ago, someone doesn't get honoured just because they didn't like conventions. Typical of authoritarian barstoods, who want us to honour them constantly, even though they discriminate and commit fruad (which this situation is, fruad by the government). Barstoods!

In 1977 at Colorado College i was lucky to take a physics demonstration class by visiting Prof. Julius Sumner Miller, Disney's Physicist. For 2 hours a morning for 3 weeks he did demonstrations and we had to write a notebook with our explanations. It was an amazing class. Dr. Brown from Back to the Future wasn't near as crazy as JSM!

You beautiful girl. I want to you girl driend

we need more movies

Great vid, thank you.

Thank you for the lesson! It's really helpful!

E pensare che tutto nasce da Evangelista Torricelli e il suo barometro ad “argento vivo”. Sarà l’ “horror vacui” a dare tutto a Pascal…

nice.

Best educational video ever. You should get golden buzzer. 🎉🎉🎉🎉

Amazing video, helped me a lot. Thank you for sharing

Hello, I am a high school teacher, I wish I could show this beautiful video to my students with an Italian translation. Machine translation is not satisfactory: can you make an adequate translation available? Thank you very much.

If the water jug was big enough to fit a person in it, would that person experience the same effects as a diver at 150ft deep ?

Dr. Visnjic: Thank you. Great video fun and great learning I thought I knew, and very well presented. That was nice to give credit to Mr. Stevin. I had some minor notes/questions, sincere apologies if they are obvious or wrong. Pls forgive the numbering, its just for me to attempt being organized! 1. The point about all points in a fluid being at same pressure isn't quite right, is it, under gravity, since the fluid has mass, if the vessel is not all at one height, isnt that correct. 2. The pressure in the vessel also wouldnt be equal everywhere, if the fluid were moving, say if the fluid was rotating in the vessel, or convecting. or vessel is in noninertial frame? 3a.. It would be great to understand the role of atmospheric pressure here, especially if it were low, say down here vapor pressure; and if gravity were much higher; 3b. and how the results would be different if the vessels tops were not open to the air. 3c. and Especially,, with the cool barrel experiment, what if the top of the 150 ft tube was sealed, before pressure applied at the barrel. what would happen, at that height,150? feet? I guess all the gases would come out of solution at the top; then the fluid water at top would starts to vaporize in near vacuum.and the plastic tube would shrinks everywhere, and the barrel still explodes? 4. And if I had a wishlist, I would love to understand the relation of static pressures, such as shown shown here, to the vessels' "capacities, like a battery, and the output Impedances" or what an EE like me would call it, (dynamic heads?)say of the different shapes as here and the same initial flluid height height, for instance the martini 630g glass vessel I would say has high capacity, initially at least, and llow output impedance to flow out of its bottom aperture, while the one with the thin top, would have low capacity and high output impedance to flow out of it's bottom aperture? Thanks for your work and cool demos, and any consideration, Best regards,

5:00 what was the point of this? if you over pressure the vessel, it will burst. if the vessel is built better, it won't.

Thank you!

Great demo but this isn’t a paradox, in fact the opposite: it’s exactly what you expect and predict from pushing the physical relationships between the parameters to the extreme. Surprisingly effective demo, like the feather and cannonball falling in a vacuum, not paradoxical.

What's her name? 👀 She's really good at teaching.

In Pascal's tube, the pressure at the bottom of the tube shouldn't it be Patm + ρgh ? Why is it only ρgh?

😏 Dutch. Pfff.

If the pressure depends solely on the difference in height (and density and force of gravity), then why don't they build water towers essentially upside down with the large tank on the ground and a small tube extending up the 40 meters or so? That would provide the same difference in height.

please upload more❤❤

Such a great video! Thank you!

Thanks for your work

Thanks professor Katrina, I never seen such beautiful professor giving very simple yet clear explanation. I wish we could have applied real time calculations as well.

What is Happen my english is not so good to Understand that

A great experiment, showing us the magic that physics brings

What is the mystery is what is the weight of the container especially if the bottom of the container is a bit flat. Does it increase based on the height of the water and not on the volume of the water i.e. the small volume can "weight" a lot ... in spite of only a small amount of water was "added".

Honestly, the explanations was soo good. Although I'm just 15, I was able to understand it completely. I'm glad I'm a able to find your yt channel. Hope you become a million subscriber channel in the future and share your knowledge with many. Thanks a lot!

Nah giesel any day 🔥🗣🗣💯

Your videos are amazing! Keep up !

This will be exactly the same as the power to shift from a smaller gear to a larger gear. This rule is also according to Pasal rule यह बिल्कुल छोटे गियर से बड़े गियर में शिफ्ट करने की शक्ति के समान होगा। यह नियम भी पासल नियम के अनुसार है

Varun Patak sir student's Give attendance here....

Hooollyyy this deserves more views!! Algorithm pls boost! This is by far one of the best academic-education videos I've seen. I've long believed that it's the practical demonstrations most students need in order to truly appreciate the sciences. Thank you

Cool

I have so much to say. This was incredible. I'm possibly going to explode from the pressure I'm under 😅 i need to ask you: what is the electrical equivalent to this hydraulic press concept?

While applying pressure before barrel bursts, it seems that pipe at other end was closed by injection. The pressure on the barrel was solely atmospheric (open one) or it was aided by a closed pipe at syringe attached at other end?

Another way to think about pressure depending on only the height of the water is to go to the edge of a lake, dig a small hole, make a channel connecting the two that's only a few centimeters deep, and then try damming that channel with your hand. The force of the water you're trying to hold back will feel negligible, even though there's a massive amount of water on the lake's side.

Very useful thank you

You never told us the answer of the pressure in the tilted container

This is no paradox. This is just obvious.

Good video

in the future and for repeat experiments - fill the vessel while the skinny tube is at ground level to act as an air bleed and when the overflow fluid fills the tube (known nominal internal volume) - then hoist the tube

great video
