Excellent
"It can be dangerous if done without the correct safety precautions." Cue massively dangerous pouring of liquid nitrogen from very big thing to very small thing.

You burp a lot
And possibly develop necrosis of the stomach and esophagus.

I love him saying...
"It can be [dangerous] if it's done without the correct safety precautions" while someone pours nitrogen from a dure into a thermos with no gloves on.

I handle this stuff quite often - it's easy to become complacent about it, but its still dangerous stuff.

Edit - Have a liquid Nitrogen experiment video - www.thenakedscientists.com/HTML/content/kitchenscience/garage-science/exp/light-bubls-in-liquid-nitrogen/
