    "abstract": "This article describes measurement of potato cannon velocity with a digitized\nmicrophone signal. A microphone is attached to the potato cannon muzzle and a\npotato is fired at an aluminum target about 10 m away. The potato\u0027s flight time\ncan be determined from the acoustic waveform by subtracting the time in the\nbarrel and time for sound to return from the target. The potato velocity is\nsimply the flight distance divided by the flight time.",
