Do not drink liquid nitrogen

Because of safety reasons all my bottles of reagents on my shelf are labeled "do not drink" (except my ddH2O, that one is labeled "only drink if very thirsty"). I always thought it was a ridiculous precaution because who in their right mind would drink from a bottle in a lab. I mean if you're going write that, might as well add "do not use for enema". Well I guess I'm just not gifted:

August 15, 2008 -- A gifted 15-year-old student from India had to be rushed to the hospital after drinking liquid nitrogen during a science class at Princeton University.

The class was part of a program run by the Connecticut-based Summer Institute for the Gifted.
