At 0:45 - "Just imagine the air being sucked out of there" - well, yes - if you were looking at any other video - but in this video, rather imagine the air being pushed out of there by the remaining pressure of air (low though it may be) being higher than the pressure in the vacuum pump. That's why you can never get a perfect vacuum - because it always takes a bit of pressure to push the remaining air out. OK - call me a nerd!
I'm here in the year 2021, I can't even make such strong vacuum and how did they make such strong vacuum back in 1650 without special rubber seals or gaskets? legend says that 8 horses on both sides can't even pull that vacuum out... Non of this makes any sense without introducing the facts of its purpose and origins...
Sir, sometimes we find it's difficult to open a container lid..Is it because of the same phenomenon??That it creates a low pressure region(If it is then how is it created??).Probably it's not vacuum inside!!Right???Sir, I need help?? Help this miserable??Lol
In my experience, opening container lids is more a matter of overcoming the friction between the lid and the container than any pressure difference. I doubt there's much of a pressure difference between the inside and outside of typical containers, but I don't know for sure.
Currently studying for my physics finals - this kind of stuff keeps me interested.
You seem to be such a good teacher, who gets everyone interested ! congrats
He explained it very clear. His experiments keep me interested in Physics.
Thank you so much for all of your valuable videos
Thank you sir my physics professor brought me here
im in middle school lol
Thank you for making me understand sir
This helped me a lot
In the calculus, Why did you get pounds (lb) when you are expecting units of Force, like for example Newtons (N)?
Because the inputs were in lbs and inches
I can really understand the topic because of your experiment thanks.....
So an old English long bow user (pulling a 200lbs bow) would be able to separate it then?
Thanks a lot sir 😊😊

interesting!
01:54 - aren't you actually letting air back into the interior as the vacuum had already removed the air from the inside?
Thank you sir

Can I embed part of your video in my UA-cam clip for teaching? Please.
Yeah offcourse it is allowed
1:45 -_-
i am from 8th standard , i just caem here from a fun fact in our chapter ... and the formula is bouncer for me 😳😱🥵
Great Video, but I feel sorry for you having to convert from imperial to metric!!
Thank you
thank you alot
the air compressor... it sounds uh.... interesting
Why don't the hemispheres crush due to air pressure when there is no air inside? Pls help.
@Fun Tv thank you
yeah why is that
Which pump did you use?

But if we heat and cool the container only then
how is this accurate to the same experment back then they didnt have the vacuum
After avacuation, these Hemisphere could not be opened even two horses are deploid on either sides of the hemispheres

Albert of Brandenburg 1490-1545 is the younger son of John Cicero 1455-99.
Thanks
I didn't understand the part of the area. Why isn't the area that couple the two halfs??
Sir if we do this process in space or by applying more force greater than atm then the sphere will open or not? In both cases
thankyou for thiss
Thanks sir
bruh my school made me watch this.
Otto von Guericke sei Dank !!!!!!!!!!!!!!!!!!!
Why not the whole area ,I mean 4. pi. r sq
Don't worry David 😂😂
So theoretically if we pumped the air out of a human, they would become very powerful.

Interesting
KVPY question
He s so funny hhhhh😂😂😂
Oh, yes! All of physics is absolutely hilarious.
Magdeburg GER -----> Not to be confused with Hamburg GER!!!
How did you do it behind your hands? Hiding from us??
He let out the air from the hemispheres
Achha hai
Hello indian like me... brother
@@exploresmartlearning4049 are you American?
Thank u u just wasted 4 min and 24 seconds of my lesson
Lol
Jk btw
fart sound
