Can You Safely "Drink" Liquid Nitrogen?

AI Thread Summary
The discussion centers around the concept of using liquid nitrogen (LN2) for a dramatic effect by "drinking" it, where the nitrogen vaporizes upon contact with the tongue, creating an insulating layer of gas. This technique allows for the production of vapor that resembles smoke, which can impress onlookers. However, significant caution is advised; only a small sip should be taken to avoid freezing injuries, as swallowing could lead to serious tissue damage. Participants express curiosity about videos demonstrating this practice and share anecdotes, including a professor's experience with it. There is also a request for more detailed information on the topic, indicating a desire for further exploration of the safety and science behind using liquid nitrogen in this manner.

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?]

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
