Air pressure bottle experiment

I do not agree with what people say here and i'd like to explain my pov, i may be wrong though. If anyone thinks i'm wrong i'd be delighted to hear why !

In the very beginning, at water level we have atmospheric pressure, the height of water is the same in the straw and in the bottle, because the air in the bottle and in the straw are both atmospheric pressure. The pressure at the inlet of the blue straw is greater than atomospheric pressure though, since there is a certain height of water to be added. The pressure at the outlet is atmospheric pressure but there is also surface tension which helps maintain the equilibrium with the inlet pressure, therefore there's no flow. Everything is at equilibrium. Then the guy pinches the straw, which doesn't allow the air from the environment to get in. By lifting the straw while keeping it pinched, the air stuck is expanding, therefore lowering its pressure (pV=nRT, right hand side of the equation is constant but on the left side we raise V therefore to keep it constant p must be lowered). Now, still while lifting the straw pinching it, the air in the straw excerts a lower pressure on the water than the air in the bottle. Therefore, water is sucked through the red straw, lowering the air bottle pressure since it now expands because of the water flow in the red straw, until equilibrium is reached (pressure at "bottle level" is the same everywhere, so p_bottle = p_redStraw + pressure due to extra height of water in the red straw, with respect to the water level).
Now we have reached equilibrium and the "highest height of water" has been raised. This is important since as mentionned before, for the blue straw, the inlet pressure depends on that highest height of water. Now when he finally stops pinching the straw, atmospheric pressure is back in the red straw, but this time we have built that extra height of water, which results in a greater water pressure at the inlet of blue straw. The inlet pressure being greater than the outlet pressure + surface tension, flow begins. Then due to inertia it keeps for a while

What the formula and rule it has ?some one explain me please ...........

100%real

You mother rascar it never works

This bad

What!!!??? You're Satan!!!

А будет ли такой же эффект с водкой? А то, когда руки трясутся... . Надо попробовать.

EBUONO PER DSRE DA BERE PER I ANIMALI ESEMPIO

It's hydronic pressure resisting atmospheric pressure when the straw is lower.

यह तेरा वर्क नहीं करता😂😂😂😂😂😂😂😂😂😂

একটু চিন্তা করার পর কাহিনি টা বুঝতে পারলাম

Thank u so much mann

MAN RESPECT

So simple and elegant. Both the experiment and the video

First thought to come to my mind: “woah that could make a sick bong”

Congratulations you just rediscovered how a siphon works. This is not new or unique.

Here two forces are acting
Thurst by liquid
Air pressure by atmosphere

Ru brief both birh kc😅 Jr crjuru v😮jturvtrhti😮vrbrgtj😅vrctkrc😢r brh😮fbbtnt😊br r😂vftyh jbryrv😮 er ce the rvbrbfrvjrkehc cr😮r krc rgrri 😮en yr😅🎉h unit I believe r 🎉 today and🎉. 😮🎉. 😅i🎉😮 🎉

wah kiya bat hai

Is this the experiment of Air Exerts pressure in upward direction

Is it a bong... sounds like a bong.

how can I make this?

how

Wonderful🎉🎉🎉🎉

Very cool. Simple yet complex.

Holy shit

pleased to see it!

Very interesting 👌

Wow to make

Is the blue straw having a hole in it where it meets red straw? And does the hole in blue clamp shut the red straw?

Like it🎉🎉🎉

Super🎉🎉

Can you send me same lines for saying in school please 🙏 🏫

Bolammare video

How to make this

Try mercury its tits

Cool

Sir kase bnaya jata hai video dhaliye

What is the theory about it

I finally know how does tap work

How 🤔😱☺️

Paraku don't try

🤬🤮🤢

That is awesome 😮

bro fr just made a water bottle bong lmao

​At first, the total air pressure and water pressure inside the bottle at the intial depth of the red straw is greater than the air pressure from outside, not great enough for water to flow out through the top of the straw, but enough to prevent air from outside from moving into the bottle( water). Same with the blue straw. As the red straw is pulled upwards, the total air pressure and water pressure in the bottle through the straw decrease because the depth decrease, eventually reaching a depth in which air pressure from outside is greater than it. Thus air moves into the bottle(water) through the straw, and as air bubbles ascend to the top space in the bottle with air, the air pressure inside the bottle increases. Then total air pressure and water pressure at the depth of the blue straw then exceeds the pressure outside the it and pushes water out from the bottle through it!
Pretty cool!!
