Joe_F BS: frat rat tp (14) RE: BS: frat rat tp 14 Apr 20


At Caltech in my time there was a demonstration at a freshman lecture of a singing sewer pipe. If you put a disk of screen (I think it was) a quarter way up a vertical length of sewer pipe and then heated it with a Bunsen burner, it would howl. To the students, this suggested unrolling a roll of toilet paper up the updraft in the chimney of a (gas) fireplace, and then lighting the bottom of it. When the flame reached the magical fraction of the chimney, it would excite a rumble that would shake the building.
