How do they create silk? What causes it to come out as a line? How do they make webs so geometrically perfect? When dows the silk start to have drop off after coming out of the spinneret? If there’s only 2 spinnerets, how do these give it so much dexterity with its web building?

I do know that a single spider can have more than one kind of spinneret.. And that all spiderweb silk is actually liquid until it emerges from her body and hits the air!… one spinneret will spin the strands of the axes of say, an orb spiderweb, another kind spins the round parts that connect the rest; and one will be “sticky” (to catch the bugs) some smooth, (no sticky on it!) And another kind she’ll use to bundle up whatever it is she catches and rolls up for later in her web… And of course this this varies widely over the tens of thousands of species of them there are on earth. And she knows instinctively which ones to use, and when! And she knows not to walk on her own sticky-kind strands!
