Newly created air water interface has a higher surface tension?
https://phys.org/news/2017-04-dynamic-surface-tension.html
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.

Droplets burst apart when they freeze
When they freeze water droplets break apart sending ice in all directions. This was only found with cameras that can capture this in unprecedented detail from the initial crystallization to the final explosion.... awesome right?

The Spirits and Surface Tension
Attached is an interesting article. It explains why we call our alcohol that we drink and how the shimmering due its low surface tension makes it 'ghostly'.

Second Liquid State???
Physicist reported in the International Journal of Nanotechnology noted that liquid water has a whole new set of properties when it hits temperatures between 40°C and 60°C. In this range, water can go into a “crossover” phase or a second liquid state where the surface tension changes and other characteristics change....
