The straw and vacuum cleaner are two rare examples of Gödel statements manifesting themselves in the material universe: when they suck, they don’t suck. But when they don’t suck, they suck.
I see what you did there, but you're a little wrong.
Straws don't suck. People who use them do. Even if they can't get them to work by sucking harder. That's how much people, those be-troubled beings can and do suck.
Yet you are still also a little right about when straws, if we were to change don't "suck" to don't work (like in milk shakes) suck (when they don't).
When seeing the design I immediately thought -- aha! maybe that's how fuel pick-up line ends, in marine (diesel) fuel tanks (that are built integral to steel hull vessels) could be made, except with the small hole in the bottom of the curve ---instead of the sides of the bottom curve, be actually at the bottom (to allow anything desired to settle out when not running be allowed to settle out instead of clog at that point).
That is, if having a small hole (just the right size compared to the others) would still work, gaining any advantage in tending towards drawing (and creating flows near the various sized holes) generally from a little higher, thereby putting just that more distance between the pick-up point(s) and lower down in the tank nearer accumulations of rust, algae growth detritus and water during the majority of the time fuel was being drawn out of the tank.
I dunno...maybe my hole thinking here sucks.
