Lens and microscope can now play their part.
The sight is perfectly astounding.

Those threads, on the borderland between the visible and the invisible, are very closely twisted twine, similar to the gold cord of our officers' sword-knots.

Moreover, they are hollow.

The infinitely slender is a tube, a channel full of a viscous moisture resembling a strong solution of gum arabic.

I can see a diaphanous trail of this moisture trickling through the broken ends.
Under the pressure of the thin glass slide that covers them on the stage of the microscope, the twists lengthen out, become crinkled ribbons, traversed from end to end, through the middle, by a dark streak, which is the empty container.
The fluid contents must ooze slowly through the side of those tubular threads, rolled into twisted strings, and thus render the network sticky.
