@evewingful It depends on how much touches you and for how long. If it's just a drop or two, nothing happens. Your hand is so hot relative to nitrogen's boiling point that a layer of gas quickly forms between you and the nitrogen that serves to protect you. Once that layer breaks down, whatever the nitrogen is in contact with begins to freeze.
@absentmindedprof It can be used to cool some materials down to where they become superconductive. These particular materials are collectively called 'high temperature superconductors.' While the name may seem odd, it takes its origins from the time when liquid helium was needed to induce superconductivity.
@11kazzo No kidding... Due to construction in the building, Steve has had to temporarily relocate his office to the classroom. Lights keep going off every 5 minutes. His arms are getting tired...
What would happen if you touched liquid nitrogen with your bare hands?

Can liquid nitrogen be uesd to create a super conductor?
