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. Liquid nitrogen looks like boiling water. If you have never seen it, we have a picture of some posted on our site.
