Take an airtight chamber. Allow a small hole just big enough to allow a strand of cooked spaghetti. Put a strand of spaghetti into the hole. Now, reduce the air pressure inside the chamber relative to the outside atmosphere (by increasing the volume of the inside of the chamber). The pasta enters the hole and fills the interior space until the air pressure inside the chamber equals that outside. NOW, reduce the volume inside the chamber, thereby increasing the air pressure relative to the outside, and the pasta comes back out! (Repeat until mom smacks you.)
All of the mechanics of the above are performed by manipulating the chamber itself. Would the process work if the manipulation was made to the outside atmosphere while the chamber remained constant? Could I, Inigo Montoya insert one end of a strand of spaghetti into your pursed and glistening lips, and then, with the rest of the noodle in my mouth, place my mouth over yours and blow it into yours?
Somebody set up this exact thought experiment in Cecil’s column on spaghetti-sucking a few years back. Except he had the airtight chamber be Erwin Schroedinger’s head, and he assumes that increasing the air pressure outside would never ever force the spaghetti strand through your mouth. Cecil doesn’t seem to address this assumption in his response…
Think first principles of physics. Your frame of reference depends on where you are standing. To an observer outside your mouth the spaghetti is being pushed in. If the pressure differential were reversed the pasta would move in the opposite direction. If you were friendly enough with someone you could push spaghetti into his or her mouth.
If that doesn’t work for you consider that vacuums can’t do shit. Think about it, how can empty space do anything? Your hoover doen’t work by sucking but the atmosphere does all the work by pushing the dirt to a place of lower pressure. The vacuum jusgt makes a place of lower pressure. Some cars have a vacuum system that include an accumulator tank. Is it “full of vacuum?” If it leaks does that mean all the vacuum gets out? Or is the atmosphere pushing its way in? The only pulling forces I know of in nature are magnetism, gravity and opposite electical charges. There is no vacuum force.
I suppose this means that all the pleasure from a **** *** is the result of atmospheric pressure but looking at it that way kind of sucks the fun out of it.
