Simple, ya can't have air pressure without containment.
Wind and temperature are influencing factors in the cause of pressure gradients.
Every time my furnace kicks on it creates wind, in my outside tank, causing pressure gradients.
Purdy stupid always tryin' to hang a handle on one.
Why you guys standin' here lookin' up? This same Jesus will come in like manner as you have seen him go. ~ Angels
The manner he left was rising. ~ 1Mind1Spirit
Peter colaborates this here...
King James Bible
We have also a more sure word of...
No, the air molecules under will have more elastic collisions, plus in that so called experiment the air is being sucked up and out. So inside the container there will be more pressure lifting against the top.
You mean a vacuum chamber.
The air under the vacuum chamber creates more pressure under it.
Thus, a lifting force.
You do know when air pressure is taken out of a container it's the outside pressure that causes it to be crushed, right?
