"WebA bubble always behaves on the principles of "Bubble dynamics". These are governed by the Rayleigh-Plesset equation. As outlined by @mikhailcazi; A bubble, while it still exists, is balanced by three factors: 1) Surface Tension of the soapy water. 2) Internal Pressure applied by the air inside the bubble on the surface. 3) Atmospheric Pressure.
