Can you actually swing from spider silk?
Veritasium · 26:57
Veritasium tests real spider silk's mechanical properties at the University of Akron — dragline silk hits ~600 MPa tensile strength (Darwin's bark spider reaches 1,600 MPa), with toughness up to 520 MJ/m³, roughly 10x Kevlar and 3x ultra-high-strength steel. Covers the nanocrystal-amorphous microstructure that gives silk its unique strength-plus-stretch combo, and the history of failed attempts to produce it at scale — from 18th-century French stockings to genetically modified spider goats — culminating in an attempt to actually swing from harvested silk.
Alösha's take: Genuinely fascinating materials science — the engineering challenge of replicating what a spider does at room temperature inside its own body is a beautiful unsolved problem.
