The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet’s interaction with its own ripples, which form what’s known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles.

In theoretical physics, the pilot wave theory was the first known example of a hidden variable theory, presented by Louis de Broglie in 1927. wikipedia

_Note the moment of 'emergence' of the droplet that happens at 1:10s_
Here is another video of exploring the concept of 'pilot waves' where the droplet is 'guided' by the wave.
