Re: Singing pipes



From the vast amount of traffic on this topic, it seems clear that many do
this demo, but from the lack of a coherent explanation (or the complexity
of such explanations) I fail to see the pedagogical value.

Not sure that I agree with this. Fun had by students removing the
heat, putting pipes on their side, discussing etc is of value in an
indefinable way. We can fall prey to the thought 'if we can't
analyse it, measure it exactly, describe it exactly' it's not worth
including

I like the demo - even for junior classes. My opinion only!!

Only George
Spagna's lab seems to make any real 'use' of the phenomenon. This seems to
me to be one of the many 'gee whiz' demos that we often get into but that
fail to educate in proportion to the time, effort, and expense invested in
them.
This is very cheap for a 'gee whiz' demo surely - very easy to set up
- very memorable . .

I think it's good value.
