Liquid nitrogen has a temperature of 77 K at standard atmospheric pressure. Being about one-fourth of room temperature, this is low enough to produce some interesting phenomena. Liquid nitrogen can be held for several hours in a vacuum flask.

Liquid nitrogen is cold enough to be below the superconducting transition of the high temperature superconductors like YBaCuO.
