Oil and water may mix under extreme pressure: Study
A UK-based study suggests that oily molecules, which normally repel water, can be forced to dissolve in water when the two substances are squeezed together under extreme pressure. By creating pressures 20 times higher than those at Mariana Trench, the deepest point on the Earth, researchers observed that methane (hydrophobic like oil) droplets mixed in water disappeared, indicating they dissolved.
