How ?

A bath of oil is vibrated and oil droplets are deposited on the surface. Thanks to the vibrations, the droplets do not coalesce, but bounce on the surface.

Bouncing Droplet

What ?

For specific values of amplitude and frequencies, the droplet start to move forward by itself : while bouncing, it create waves with which it interacts.

walker at sunset

Why ?

This object has been called a walking droplet, or a dotwave, and behaves somehow like an elementary particle, a particle and a wave at the same time.
