Suction cup holds onto to surfaces | Atmospheric Pressure | Physics 

I really like the simplicity of something like this

great and easy to follow explanation!

Thank you so much I was not able to get this topic so nicely but now I will be able to get 20/20 wish me luck !

If the dish and mirror are on the table then how does the initial pulling work? There is no air on the other side of the mirror to push it against the vacuum in the sucker

Can it stay stuck indefinitely or at some point it releases itself without having to lift the edge?

Nice explanation!

What I wanna know is... Air pressure is 14PSI yeah? So on a sucker with a surface area of one inch, why isn't 14 pounds enough to pull it? Or if you had a larger sucker, why isn't 14 pounds or more enough to start to create a volume of space under vacuum? I mean conceptually it makes sense that you can't pull something apart without introducing something in between, but how do you explain this scientifically? What's the force holding them together if is greater than simply the atmospheric force? A vacuum doesn't have any mass, so why can't it be created in a volume under a sucker? It's not like it's creating air out of nothing, it's just the sucker material moving away from the surface material with nothing in between...

Very very nice explanation now I can do my activity very well and submit it to sir .. tq a lot

This was very well done!

*Suction cup man want's to know your location*

Drinking game. Take a shot every time he says "sucker"

Your English is so much good 👍

Thanks

can we do this with other materials and will this ever work on skin if you spend enough time designing it??

Thanks for telling and explaining

from where can i get these

Thank sir

Good Explanantion Sir

Thank you.i needed this,im making coffee table with a big glass,40cm by 1m.im wondering if it can last years holding that glass

Size volume weight lifting capacity material strengths If we make a 1000000 cubic km Cylinder then how much energy we trapped

Cool physics man

Very nice

Holding my palm together real tight but doesn't experience it.

nice explain

super

Time

Nice

Hi again 8-B

the mirror isnt metal..

Ty sir

Man i was searching for that white thing for wall I didn’t know this is sucker cup😂

Maja agaya

anyone from science class

Lol

😂

Is it OK to say that this video "sucks" ?
