Liquid nitrogen is made of two nitrogen atoms bonded into a molecule,
just like the nitrogen in the air. The only difference is that it is a liquid
instead of a gas because it's kept colder than its boiling point — the
temperature at which liquid turns into a gas.
Nitrogen is non-toxic, odorless, and colorless. It is relatively inert. It is not flammable.
Pouring small amount of liquid nitrogen into your hand won’t hurt, as long as you get a few seconds of recovery time between pours.
Please don’t try this at home!!
