Newly created air water interface has a higher surface tension than the equilibrium of 72.75 mN/m....making it around 90 mN/m.

Professor Bonn states that "the method of studying droplet breakup dispenses with the previous difficulties: the experimental procedure is very robust, and the associated pinch-off dynamics well understood.
