This may not be the most efficient method of preparing shrimp, but it's definitely the most explodey. The double-barrel "cooking detonation velocity" cannon propels prawns through jets of egg, flour, flame, and heavy metal music to land fully cooked on a plate.
The video was commissioned by Japanese mobile provider DoCoMo, to demonstrate that their service is fast, like a high-velocity fried prawn detonated in a cooking explosion. Or something. It's all real, though, and the video description claims the crew actually ate the cannon-fried shrimp afterward.
I'll leave you with this safety disclaimer, courtesy of machine translation: "Since this recipe is dangerous, please do not imitate absolutely."
