Braniac, the same show who did the experiment I posted (with the helium) did exactly this experiment. They took a wine glass, and an opera singer tried to break it with the correct pitch. It didn't work. Then they got a rock band to play really loud and put the wine glass near the guitar amp. It took a while but evetually it broke.

Oh, I thought this was about the Hazel O'Connor film!
I remember seeing this done on telly (late '70s or early '80s) where the singer's voice was amplified and the glass was placed right next to the speaker.

. . . sound was amplified . . . glass right next to speaker . . . yep, wouldn't even need a hammer, would you? If it was loud enough it might even break a cast iron anvil! Eu

And, how does one determine the pitch?, fundemental, or like the oboe etc 1st overtone [octave] which, I'm told, has the greater volume. I recall inducing a musical tone by circling [sp?] a wine glass rim with a wetted finger, would that be its critical pitch?? Acoustic advice needed !! Don
Thanx, Mark, Don

I think the resonant frequency of a glass is the same as when played with a wetted finger.
If you ping a glass you hear more overtones.

And then there's the way The Fat Lady (doorkeeper to the Griffyndor quarters) shatters glass in one of the "Harry Potter" movies.... ;-)
I'll bet I could break glass with my voice with the greatest of ease. All I'd have to do is catch people standing around innocently with their beverages on a hard surface, such as a brick terrace. Without warning, I'd belt out a tune--any tune would do--in my usual key of Way Off. They'd drop their glasses as they run, screaming....
