Japanese mobile phone operator DOCOMO knows how to effectively advertise the speed of their 4G LTE network. To do so, they created this cannon that not only shoots the ingredients for dumplings, but it preps and cooks the tasty treat in just a few seconds. Pretty crazy, but it works.
Now if they can just put these in restaurants and let people make them for themselves, they will be printing money. Making food with cannons may be the next big thing.
