Can you break glass with sound?

An opera singer hits a high note and this shatters a glass in the drawing room. This may have appeared in the movies, but is it really possible to shatter glass with sound?
A glass has a natural resonance, a frequency at which it will vibrate easily. A recent example of resonance was the millennium walkway in London, which oscillated alarmingly when a large number of people walked on it (this has now be cured). Blow across a beer bottle and you might get a note. This is another example of a resonance; in this case the air in the bottle neck is resonating against the spring provided by the air in the main body of the bottle. In the case of the glass we are trying to shatter, the body of the glass vibrates at resonance. If the force making the glass vibrate is big enough, the size of the vibration will become so large that the glass breaks. The most dramatic example of this was the Tacoma narrow bridge which was oscillated by cross-winds so strongly that it broke.
