'We hear that... undergraduate stupidity knows no

bounds. In an attempt to impress his or her

classmates, a student took a sip of liquid

nitrogen to prove that it is safe.

It isn't. Within two seconds, the victim had

collapsed in intense pain, unable to breathe and

eventually passed out.

All-night surgery ensued.

"My entire upper gastrointestinal tract was badly

scarred and perforated," the hapless student

recounts in an anonymous letter to the journal

Chemical Health & Safety (vol. 9, p. 4).

"They took away part of my stomach and had my

entire digestive system, top to bottom, running on

machine power for a while." The expanding gas also

collapsed one lung.

Eight weeks later the student was discharged from

hospital.

A little wiser, we hope.'
