jiggles

Jiggles refers to a slight, often rapid, shaking or quivering motion. This movement is typically characterized by a loose and irregular oscillation, distinct from a more rigid vibration. The term is frequently used to describe the movement of soft, pliable objects or substances that lack a firm structure. For instance, the movement of jelly when disturbed, or the way certain muscles might appear to move under the skin when a person is excited or surprised, can be described as jiggling.

The phenomenon of jiggling is often a visual cue that indicates the presence of a flexible material. It is a common characteristic observed in food items like desserts made with gelatin or pudding, as well as in some types of toys. The rate and amplitude of the jiggle can vary depending on the object's density, material properties, and the force applied to it. In some contexts, jiggling can be associated with a sense of playfulness or even mild annoyance, depending on the situation. The scientific explanation behind jiggling involves the transfer of kinetic energy through a non-rigid medium, causing parts of the object to move independently and in a cascading fashion.
