Q: "How does one measure the height of a building using a barometer?"
A: Drop the barometer off the building onto someones head, killing them
outright.  Wait for the next day's papers and read the part where is
says "A man (39)  was killed yesterday when a scientist (26) dropped a
barometer from the top of an [x] foot building".
