I had some students try this a few years ago. They measured the resonant
frequency of the glass and then subjected it to a loud sound at that
frequency. The video showed it shattering. Only later I learned that after
many tries they gave up and shot the glass with a BB gun. It still looked
good.

A couple of my students are trying to break glass with sound. So, some
questions:

1) Has anyone had any luck doing this? How?

2) What's the pira website address?

3) Does tap-l still exist, and if so, does anyone have subscription info?

Thanks.
