Description
Foamification using siphons and foamers creates airy textures by dissolving nitrous oxide in cold liquids and releasing it to form microbubbles.
Technical
Nitrous oxide dissolves in the liquid at low temperatures and high pressure, forming a supersaturated solution. Upon pressure release, the gas expands, creating microbubbles that are stabilized by surfactant films. The resulting foam is a colloidal dispersion of gas in liquid, with stability governed by surface tension and viscosity.
