Breaking glass with sound! (A little more scientific than Memorex, courtesy of MIT.)

There is a super slomo shot at about 1:40. Watching the glass oscillate is kind of amazing.

Also on the subject of resonating glass, see the glass harmonica.

Rubbing the rim of a wine glass with a wet finger will cause it to resonate at its resonant frequency. The glass is placed in front of a speaker playing a sine wave, created by the function generator, of this same frequency. When the amplitude is turned up, we can see by shining a strobe light at the glass that this resonant frequency causes it to oscillate. When the glass becomes too stressed, it will shatter, which we see very clearly on high speed video.
