Supercool technique keeps liquids liquid well below freezing

“Our approach, which we dubbed ‘deep supercooling,’ is simply to cover the surface of such a liquid with a solution that does not mix with water, like mineral oil, to block the interface between water and air, which is the major site of crystallization,” says O. Berk Usta, co-corresponding author of the study. “This surprisingly simple, practical and low-cost approach to supercooling solutions for extended periods can enable many medical and food preservation methods, as well as fundamental experiments that were not previously possible.”
