This is the best reason for you to diet yet: scientists can now recover speech from potato chip bags. MIT, Microsoft, and Adobe researchers have built an algorithm that uses vibrations to recreate an audio signal. They have so far been able to pull speech by videoing the bag through soundproof glass 15 feet away. They've also recovered audio from aluminum foil, the surface of a glass of water, and leaves of a potted plant. “The motion of this vibration creates a very subtle visual signal that’s usually invisible to the naked eye. People didn’t realize that this information was there,” one of the authors of an upcoming research paper said.
