One hypothesized explanation imagines the existence of a line of first order phase transitions separating two liquid phases and terminating at a novel \"liquid-liquid\" critical point in a region of low temperature ($T \\approx 250 \\rm{K}$) and high pressure ($P \\approx 200 \\rm{MPa}$). Here we analyze a common model of water, the ST2 model, and find that the entire system flips between liquid states of high and low density.
