We posted about this novel use of carbon nanotubes as audio speakers on Monday, but today we have a video of the real deal, courtesy of the American Chemical Society. The first part of the video shows the transparency of such a speaker. The second part is an illustration of the way the CNTs create the sound by going through rapid heating-cooling cycles instead of vibrations. The third part shows how the sound quality is unaffected by stretching. Finally, the video shows a CNT speaker sewn onto a small, waving flag.
