amirite?

You've cracked the great mystery of the diaphragm.. We're made of spinning blades anon.

But the reason I am here on /sci/ is because...
well... i still don't understand

if a fan BLOWS air >>>

how can a fan SUCK air <<< ?

is it like...

if you take a blanket or towel and spin it really fast and let it hover an inch above the floor all the dust would move around...

and then if u apply glue (vacuum filter) all over the blanket the dust that would rise would stick to the blanket?

Air, like any gas, is a bunch of molecules bouncing around and colliding with each other. When one area has less molecules than another, it's easier for molecules from the denser area to get to the less dense area, because there are fewer molecules pushing it away from the less dense area and more molecules in the dense area pushing it towards the less dense area. When you breathe in, your muscles stretch, increasing the volume of your lungs, decreasing the density of air. This forces air into the less dense lungs until density balances.

Wind turbines are entirely different, they push air mechanically. When you push air towards one direction you are also sucking air away from the opposite direction.

and since this thread is going nowhere,

will someone just post some good links to how a vacuum works?? or what makes it work???

I googled and it only showed me vacuum cleaner stuff, it said air pressure, but it didn't show the mechanics

THEN TELL ME WHY

when you put your face in front of a fan you can feel air on your face

but if you go behind the fan, you can't feel your face being sucked

Because it's not powerful enough. Air is a lot easier to move than a face.

ok, i thought so i was just trying to be funny

but i see there are many ways to create a vacuum now,, not worth my time to research

because really nobody will ever know how the vacuum of a black hole works ;)

let this thread die

it's going to get religious in here
