here is an excerpt:
the MIT team placed a bag of potato chips near people singing and having conversations. The researchers recorded the bag of chips, and, while it seemed to be perfectly still to the naked eye, the camera was able to pick up some slight movements. Those movements, the MIT team theorized, were caused by the pressure waves from the nearby noise. The MIT lab collected data about those movements and was able to translate those movements into sound, coming pretty close to approximating the conversations etc. that the potato chip bag “heard.
