Liquid nitrogen is simply nitrogen gas in its liquid state. The stuff is so cold you can consider it like an acid if you are ever stupid enough to stick your finger in there without cryogenic protection.
By immersing them in liquid nitrogen you can turn marshmallows hard as bullets, shatter flowers like glass, turn a soft peach into something that can hammer nails into wood, and a whole lot of other things.

Can liquid nitrogen be contaminated?
Yes. Liquid nitrogen can contain liquid oxygen, or liquid argon. These are generally removed during the manufacturing process.
Why do rockets use liquid nitrogen?
Rockets typically use Liquid oxygen and liquid hydrogen for fuel. I suspect this is what you are asking. I know of no rocket that uses liquid nitrogen.
Does liquid nitrogen Sublimate?
Liquid nitrogen is not dry ice. Dry ice is a solid form of carbon dioxide and liquid nitrogen is pure nitrogen in liquid form. Dry ice is frozen nitrogen. Liquid nitrogen is also frozen nitrogen, but is also pressurized. That's why it's in large, steel boxes. Chur.
What is colder helium or hydrogen?
Liquid Helium is colder than Liquid Hydrogen.
What are the two main gases?
Hydrogen and Nitrogen. Or oxygen and carbon dioxide, or carbon monoxide.
What is colder - liquid nitrogen or liquid heluim?
Liquid helium is a lot colder than liquid nitrogen.
Is liquid methane colder than liquid nitrogen?
No, at their boiling points liquid nitrogen is colder than liquid methane.
Is liquid nitrogen colder than nitrogen gas?
At the same pressure yes, liquid nitrogen is colder than gaseous nitrogen.
Why is liquid nitrogen used to fast freeze food instead of liquid oxygen?
There are two reasons. First, liquid nitrogen is colder than liquid oxygen and thus more effective at flash freezing. Second, liquid oxygen is a fire hazard; it creates an atmosphere of pure oxygen that allows substances to burn more easily. Nitrogen does not support combustion.
What burns you as it gets colder?
liquid nitrogen
How can you get liquid oxygen using liquid nitrogen?
Liquid nitrogen is colder than liquid oxygen. You use the liquid nitrogen to chill the oxygen in the air and liquid oxygen will form. Liquid water and dry Ice (CO2) should also form due to their presence as well, but not in large quantity. WARNING!! High concentrations of oxygen should be considered dangerous. When exposed to a small ignition source, it can cause flammable materials to combust much like an explosion, and will cause normally non flammable materials to burn readily. Human flesh burns better than wood after being exposed to 100% oxygen for a period of time. Please be careful.
Is liquid nitrogen an oxidizer?
dry ice −56.4 °C and liquid nitrogen is −196 °C
Why is liquid nitrogen and oxygen transported as a liquid into space?
Liquid Oxygen and Liquid Hydrogen are used as rocket fuel as it is the most effecient way to thrust rockets into space, Liquid Nitrogen is not transported into space.
How cold is liquid nitrogen?
It gets as cold at -300 degrees Fahrenheit or colder
Can liquid nitrogen be contaminated?
Yes. Liquid nitrogen can contain liquid oxygen, or liquid argon. These are generally removed during the manufacturing process.
Can liquid nitrogen freeze the wind?
No. The wind is composed of a small amount of water vapor and about 20% oxygen and about 80% nitrogen. The water vapor may freeze but the oxygen and the nitrogen cannot freeze at the temperature of liquid nitrogen. Oxygen has a much lower freezing point than liquid nitrogen and if the nitrogen were to be frozen, liquid nitrogen is not cold enough to freeze it...sort of like trying to make ice using cold water.
How could you separate liquid nitrogen and liquid oxygen?
By fractional distillation. Allow liquid air to get less cold. At around 77.4K, nitrogen will boil off while oxygen will remain liquid. The temperature will begin to rise again when all the nitrogen has boiled off.
