Strange behavior of bouncing drops demonstrates pilot-wave dynamics in action

A research team led by Yves Couder at the Université Paris Diderot recently discovered that it’s possible to make a tiny fluid droplet levitate on the surface of a vibrating bath, walking or bouncing across, propelled by its own wave field. Surprisingly, these walking droplets exhibit certain features previously thought to be exclusive to the microscopic quantum realm.
