Silk from a spider web is remarkably strong for its very small thickness.

The longer version

Thin strands of silk perform well because useful strength comes from how protein chains are arranged rather than from bulk. Crystalline blocks supply stiffness while softer stretches supply elasticity, so the fibre absorbs energy instead of snapping. Moisture in the air seems to keep the material flexible rather than brittle.

That combination lets a thread stop a flying insect without tearing, despite weighing almost nothing. Because silk is drawn out rather than manufactured, flaws are rarer than in many human-made fibres. Different glands produce different blends, so some lines prioritise stretchiness while others favour raw holding power.
