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?

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....
