Liquid nitrogen—LN₂—is nitrogen in a liquid state at low temperature.
Liquid nitrogen has a boiling point of about −195.8 °C. It is produced industrially by fractional distillation of liquid air. It is a colorless, low viscosity liquid that is widely used as a coolant.

Since it is obtained from the atmosphere, liquid nitrogen is inexpensive and is rarely refrigerated. It is kept in insulated containers called Dewars and is allowed to boil away.
Since it is boiling, most of the liquid nitrogen used in laboratories and in cryogenics shows is at a temperature of 77.2 K.
Does Styrofoam hold liquid nitrogen?
Other than expensive dewars, which can keep the liquid nitrogen for a long time, you can also keep it in just a plain styrofoam cooler of some kind.
