Snap, Crackle, Pop

Snap, Crackle, and Pop are the familiar sounds made by breakfast cereal brands like Rice Krispies when milk is added. These sounds result from the tiny starch and gas bubbles trapped within the cereal's structure. When milk contacts the cereal, the bubbles rapidly burst or collapse due to moisture and pressure changes, producing audible snaps, cracks, or pops. This phenomenon occurs because of the cereal's porous composition and the interaction with liquids, creating a satisfying auditory cue that emphasizes the cereal's crispness and freshness.
