The Popinator is a voice activated popcorn launcher | Geek-Cetera |

The Popinator is a voice activated popcorn launching machine. It sits there waiting for you to say the word “pop,” at which point the top of the machine lifts up to reveal a launcher that shoots out a single piece of popcorn in the direction of your mouth.

How does it know where to fire the popcorn? Ted, the electrical engineer in the video, explains how they employed binaural microphones to figure out where your voice originated from using “small differences in the arrival time of sound waves.”
