You still need nucleation sites. For gas to spontaneously form bubbles within the bulk liquid is actually very difficult due to energy constraints, this is why when you open a bottle of sparkling water you typically get a pop, but it doesn't usually (if it's been standing for a while) transform immediately to foam. Typically bubbles actually grow from microscopic nucleation sites, which might be microscopic bubbles in the bulk, surface irregularities of the container, turbulence and suspended particles.
