Barometer

The earliest account of the “barometer” legend we’ve found so far comes from a 1958 Reader’s Digest collection, and the tale is usually identified as being the invention of Dr. Alexander Calandra, who included a first-person account of it in a 1961 textbook (The Teaching of Elementary Science of Mathematics) and published it as an article in Saturday Review in 1968.
