It's the fact that liquid nitrogen is so cold that makes it dangerous. It causes extreme burns or if it gets to the stomach it warms and expands and can lead to a burst stomach.

I can't understand how anyone could hold a glass containing liquid nitrogen, would have thought it would be too cold. When I worked in a lab someone filled my wellies with liquid nitrogen. They went rock hard and the rubber cracked and disintegrated. Oh, I wasn't wearing them at the time!
