I've heard about this one from an acquaintance who says he was in the
lab, but have to wonder if it's true.

Quant lab.  Students doing titrations.  Professor warns students,
"don't use compressed air to dry glassware."   One student ignores or
doesn't hear warning, sticks a buret against the air tap, opens tap
full on.  Buret is shot across the room...into the flesh of another
student.  Screams, general consternation, and the injured student
looks down as blood begins to flow out the stopcock of the buret.

With remarkable presence of mind, the professor walks up and closes
the stopcock to stop the flow.
