A volumetric flask containing liquid cyclohexane is depressurised to a very low pressure by turbomolecular vacuum pump. The rapid drop in pressure results in a rapid drop in temperature, causing the substance to temporarily freeze, but the system is unstable, flirting with the triple point (a point of pressure and temperature at which substance is simultaneously solid, liquid, and gas). The result is a fluctuation between all three states of matter, in a rather stunning display of chemistry and
