If one mixes flourine gas and sodium, without turning on the hood vent sucker thing, the nuns at the all-girls school become really agitated and scream shrilly for everyone to "GET OUT!"

They evacuate the entire school. Envision flying veils and flapping coifs.

The fire department responds and firemen race up and down four flights of long, spiral terrazo stairs.

This latter is a definite plus for gaggles of teenage girls.

The weeks of "on your knees" penance, and endless lectures are not nearly so wonderful. But 45 years later, one can still cherish the memory of the moment, so maybe the information is not all that useless.

Unrelated: On three occasions, many years apart, I have been approached by flying ants, which landed in front of me, plucked off their wings, placed them carefully in the form of an X, and walked away. ?????
