[AT] Culverts

[Larry Goss]

LOL! A steady and very strong southerly wind is one of the unadvertised features of Oklahoma, Charlie.  I used to give a demonstration to middle school students called,"Strings, Bells, Horns, and Whistles,"  where I demonstrated those four forms of "making music" for the kids.  In assembling some standard hardware items so I could get musical tones out of them, I discovered that you don't have to blow across the end of a pipe to make the air vibrate.  The fact that the wind can blow through a corregated pipe is all it takes.  The corregations cause enough pressure and rarifaction of the air as it passes through to make the culvert whistle.  Try it yourself.  The next time you see an unpackaged supply pipe with the spiral exterior so you can bend it around under a sink or toilet tank, blow through it.  It WILL whistle.

Culvert or a drain tile here.  I guess the wind doesn't blow across the 
prairie fast enough here to call them a whistle?

Here in Sask. a culvert has never been known as anything other than a
culvert as far as I know.
