Why can't air PULL on a surface? Air is made up of molecules.
Molecules have mass. Anything with mass can attract anything else
with mass, can't it?
Gravity?
You're not serious.
Anti-gravity in this case. If air can push something, why can't it
pull something?
No need to postulate anti-gravity to find a case where air can "pull" on a
surface - just invoke van der Waals force! :-)
Please, don't!
