Liquids at Large Negative Pressures: Water at the Homogeneous Nucleation Limit

An isochoric cooling method for obtaining unprecedented tensions on liquids was used to determine the homogeneous nucleation limit for stretching of water at a variety of water densities, and confirms the existence of a density maximum at 42�C and –140 megapascals and greatly strengthens the basis for Speedy's conjecture of a reentrant spinodal for water.
