As far as futuristic design concepts go "Capsule," a fire safety device by Woo Seok Park, certainly looks the part. And I adore the idea of the little heat-sensitive balls that can be thrown or rolled into the area of a fire where they will explode in a burst of fire-extinguishing powder. But I have to question the merit of a tank of oxygen being anywhere near a fire at all, no matter how nice it might be to breathe a lungful or two of fresh air when trying to escape a fire.
Keep thinking about those extinguisher balls, Park, but leave the explodo gas outside.
