What it is

A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.

Why Hacker News recommends it

Cited in pilot-wave theory threads as a vivid visualization of how quantum-like behavior can arise in a classical system.
