This is a video demonstrating second-order critical point behavior. The mixture of methanol and cyclohexane is brought together under room temperature (20 C). The mixture is then placed in a warm water bath at 50 C, where the two states are able to mix into a single state. As the temperature of the bath lowers below the critical point of the mixture, the density fluctuations in the mixture result in the scattering of visible light.
