SUMMARY

The discussion centers on the practice of "drinking" liquid nitrogen (LN2) for entertainment purposes, highlighting that the nitrogen vaporizes upon contact with the tongue, creating an insulating layer of gas. Participants emphasize the importance of safety, advising against swallowing LN2 to prevent freezing of the esophagus and surrounding tissues. The conversation also references a personal anecdote about a professor who performed this act during a chemistry class, further illustrating its potential risks and effects.

PREREQUISITES
  • Understanding of liquid nitrogen properties and behavior
  • Knowledge of human anatomy, specifically the epiglottis and esophagus
  • Familiarity with safety protocols when handling cryogenic substances
  • Basic principles of gas behavior and phase changes
NEXT STEPS
  • Research the safety measures for handling liquid nitrogen
  • Explore the physiological effects of cryogenic substances on human tissue
  • Investigate demonstrations of liquid nitrogen in educational settings
  • Learn about the physical properties of gases and their applications in culinary arts
USEFUL FOR

Individuals interested in chemistry demonstrations, safety in handling cryogenic materials, and those exploring the intersection of science and entertainment, including educators and science communicators.

Another trick you can do is to "drink" LN2. since the nitrogen will vaporize when it gets near your tongue, it will float on an insulating bed of
nitrogen gas and not actually freeze your tongue. You can then blow smoke
and impress your friends. Important Note: don't drink very much at a time
(just a sip) otherwise your skin temperature may eventually get to freezing,
and also do not actually swallow since your epiglotis will seal off your
esophagus and hold the LN2 long enough to freeze the surrounding tissue.

Where can I see a video of this? Has anyone tried it or know someone who has? What are your thoughts if I said I wanted to try it?
 
Chemistry news on Phys.org
My professor actually did it when I took gen chem. He then spit it out all over the place.
 
Anyone else have input? I was hoping GCT would make an appearance.

Seen this before?

[edit:Its just a page describing how to make a drink called "liquid nitrogen."

I just thought this might not be good for physicsforums?]
