Have you ever seen liquid nitrogen hit 100 boiling water? So before we get to that, let me introduce you to the properties of liquid nitrogen

Liquid nitrogen is liquid nitrogen, molecular weight 28.013, relative density 0.8081(-195.8℃), density 1.2507kg/m3(at 0℃, 1 atmosphere), melting point -209.86℃, boiling point -195.8℃, critical temperature -147.05℃, critical pressure 3.39 MPa (33.5 atmosphere), Critical density 0.31 kg/kg, liquid density 0.8 L kg/kg (boiling point), latent heat of evaporation 161.19 kilojoules/kg, constant pressure specific heat 1.034 kilojoules/kg ·℃; Thermal conductivity 2.28×10-4 joules/cm · SEC ·℃. It is colorless, transparent, tasteless, non-toxic and transparent liquid with low viscosity. It is not heat and electricity conduction, not spontaneous combustion, stable chemical properties, and does not combine with any substances.

Liquid nitrogen is a more convenient cold source. Because of its unique properties, liquid nitrogen has been gradually paid attention to and recognized by people, and has been more and more widely used in animal husbandry, medical industry, food industry, and cryogenic research fields. In electronics, metallurgy, aerospace, machinery manufacturing and other aspects of the application of expanding and development.

Below from a group of pictures to see the wonders of liquid nitrogen collision boiling water.

If you just look at the picture without a specific explanation, it's easy to mistake it for some kind of chemical experiment.

Finally, it's important to note that there's no danger in doing this experiment in an open space. But it must not be played in small Spaces, or there may be unspeakable and dangerous consequences.
