Crystal Glass music question?

[Granite]

For all the physics geeks -

You know those guys who play music by rubbing the tops of partially full crystal glasses. I was randomly wondering - Is it possible to fill the glass enough so rubbing the top creates a sound (aka frequency) that will shatter the glass?

As I said random question...

Hum .... don't really know. I'm not really a physicist, but i think that if the glass produce a sound at a certain frequency, it is because it is capable to vibrate at this frequency. And this is this frequency you have to use to break the glass. How come the glass doesn't break? Maybe because the sound is not powerful enough.
But i think you could break the glass if you could sing the same note but louder.


just my 2 cents, though ...

this is called a phenomenon of resonance (not sure of the name in english though .. i'm french)
