# Water Droplet Saturation Phenomenon

What is the term used to describe the behaviour of (for example) a water droplet in free fall when it has reached a certain speed and then the force on the droplet causes the larger droplet to disperse into many smaller sized droplets. This also occurs in a Taylor Cone when using electrostatic spray. The charge builds in the liquid until it eventually reaches a critical charge and then the negatively charged droplet releases.
