Popping Corn One Kernel at a Time

Design students Laurent Beirnaert, Pierre Bouvier, and Paul Tubiana created "Oncle Sam," a machine that pops popcorn one kernel at a time. It can even butter and salt each individual kernel! Not all that efficient, but as an art project it's fun to watch. The contraption is part of a French exhibit called "Low Tech Factory." See a video of it working at Laughing Squid. Link
