The surface tension acts at the air-water interface and tends to make the bubble smaller (by decreasing the surface area of the interface).

Once a bubble does begin to grow, the pressure due to the surface tension reduces, so it expands explosively.
en.wikipedia.org
As for the entire fluid flow, surface tension plays an important role in flow control.
en.wikipedia.org
It turns out the excess pressure due to surface tension is inversely proportional to the diameter of the bubble.
en.wikipedia.org
The sphere therefore appears in nature: for example, bubbles and small water drops are roughly spherical because the surface tension locally minimizes surface area.
en.wikipedia.org
It is during this process that a characteristic pressure pattern develops (see picture), which is evaluated for determining the surface tension.
en.wikipedia.org
Instead, contact angles can be used to indirectly estimate the surface tension of polymer surfaces.
en.wikipedia.org
In this moment, the weight of the drops is in an equilibrium state with the surface tension.
en.wikipedia.org
As the ring is pulled out of the liquid, the tension required is precisely measured in order to determine the surface tension of the liquid.
en.wikipedia.org
This is a function of the hirudin and other compounds that reduce the surface tension of the blood.
