Sound is used to drive a wineglass into resonance behavior. In the first clip we see in 600 fps a glass vibrating at its fundamental frequency, with a small strip of paper bouncing up and down as it straddles the lip of the glass. The next two clips show us breaking a (different) glass, first showing the break in 30 fps and then in 600 fps, with the sound from the 30 fps footage slowed down for added drama. Please use eye and ear protection when doing this at home!For details on our setup see http://sciencedemonstrations.fas.harvard.edu/icb/icb.do?keyword=k16940&panel=icb.pagecontent263162%3Ar%241%3Fname%3Dindepth.html&pageid=icb.page80864&pageContentId=icb.pagecontent263162&state=maximize
