• Resumen

  • We describe the fluid dynamics principles governing the up-down oscillatory cycling of a bubble- covered, low-density, low-mass ball of material (referred to henceforth as a �fizz-ball�) immersed inside a glass of bubbling (super-saturated) carbonated liquid. The bubbles serve to desaturate the liquid of excess CO2. The fizz-ball acts as a catalyst to speed up this process.
