A self-pressurising dewar (silver) being filled with liquid nitrogen from a larger storage tank (white). A cryogenic storage dewar (or simply dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature.
A Union Pacific Railroad 20 ft tank container and a 20 ft open-top container with canvas cover aboard a spine car.. A liquid hydrogen tank-tainer also known as a liquid hydrogen tank container is a specialized type of container designed to carry cryogenic liquid hydrogen (LH 2) on standard intermodal equipment.

A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that slows the speed at which its contents change in temperature. It greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings by trying to be as adiabatic as possible.
Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...

Roll out the potato candy to a 12-by-10-inch rectangle (about ¼-inch thick), dusting the top with powdered sugar if it becomes sticky. Spread the peanut butter in an even layer over the potato candy.
A woman who saved years' worth of daily text messages from her dad turned them into a sentimental Christmas gift that left her dad in tears. Leah Doherty of Ohio told "Good Morning America" that ...
The clear hydrographic film is water-soluble and should dwell on top of the water for 60-75 seconds. Safely using a fitted respirator, the film is then sprayed with an activator solution to dissolve the film and return it to its fluid state. Once dipping is begun, the surface tension of the water will allow the pattern to curve around any shape ...
