Otis Cut the Rope

Elevators became safe when one inventor cut his own cable in public

In 1854, a man rode a platform high above a crowd and had its only rope cut. What did he know that they didn't?

You'll find out

  • What caught the falling platform
  • Why a broken part can mean safety
  • Where this idea protects you today

Why it matters

Skyscrapers, trains and power tools are safe for the same reason: they're designed to break in the right direction.
