Electrification or molecular undercoordination not only changes the Tm, TN, and the evaporation point TV contrastingly to compression but also makes the anomalous water even more fascinating. For example, water skin is naturally the toughest, and ice is very slippery . The surface stress of water reaches 72.75 mJ/m 2 at 293 K, which is higher than 26.6 mJ/m 2 of the CCl4 solution. When a water droplet falls on water, it bounces around or rests on the surface before eventually disappearing, demonstrating the elasticity, hydrophobicity, and repulsivity of the contacting interfaces. Numerical duplication of the thermal effect on the surface stress resulted in the 182 K Debye temperature and the 0.09 eV cohesive energy for the O:H of the tetrahedrally coordinated H2O molecule at the surface .
