Water vapor, the gas phase of water, is the gas most commonly reported by experients of aerokinesis in regards to influence of flow. This can be for several reasons including availability and an array of dynamics making water vapor the simplest form of gas to influence.

In addition, water vapor is lighter than air or less dense than dry air and at equivalent temperatures, it is buoyant in respects to dry air. This lightness or lack of density may be another reason water vapor is the most commonly influenced gas.

Unfortunately like fluid dynamics, aerokinesis, is an active field of research with many unsolved or partly solved problems. We do not currently posses the technology to observe individual gas particles (atoms or molecules). Therefore, only theoretical calculations give suggestions as to how they move and behave.
