What You Need to Know
Nitrous oxide (N₂O) dissolves into the liquid under 2–3 atm pressure, lowering surface tension and creating microbubbles that trap air. Upon release, the gas expands, producing a light, airy foam. The process is highly dependent on temperature, viscosity, and whipping time to maintain bubble stability.
The Science
Primary Reaction
