Here’s a Straight Dope classic: “How does one suck in a piece of spaghetti? Think about it. How one sucks milk through a straw is easy. The lowered pressure in the mouth due to sucking causes the air pressure over the milk to force the liquid up. But if one pushes on the end of a piece of spaghetti it just buckles. The mouth is closed and sealed over the sides of the spaghetti, so passing air doesn’t drag it along. Somehow the air very close to the mouth must obliquely communicate a force along the length. . .” It’s more complicated than you think.
