Under the Sink: The Physics of Garbage Disposals

In this Science Corner episode, we pull back the splash guard to reveal how a kitchen garbage disposal really works. From torque and flywheels to impellers and grind rings, we’ll unpack how impact, shear forces, and water flow break down food. We’ll explore Bernoulli-driven drainage, cavitation, cooling, and lubrication, plus how clever design minimizes noise and vibration. A surprisingly deep dive into a device you use every day.
