Cause air pressure presses on everything from every direction. Quoting: Halcyon Dayz, FCD
Do you now know why balloons fly?
Air pressure is not weight..
A bathroom scale should feel the weight of about a
ton from atmospheric gas.
Why doesn't it..?
You have already said humans aren't affected by
the weight of the atmosphere because we are liquid..
and liquid doesn't compress easily.
So... we can't feel the weight..?
We have all of this weight pressing down... that we don't feel..which creates air pressure...
A bathroom scale compresses easily.. and it is not liquid.
It is not a balloon, either.
But it measures nothing..?
You don't know.
