Fire Extinguisher Balls

An Anonymous Coward writes "The Far Eastern Economic Review has this article about a Thai inventor who has come up with throwable fire extinguisher balls. You just toss them into the fire, or place them in high risk areas, and - boom - they explode from the heat and spew various fire-retardants all over the place. According to the article, they will soon be on sale in Thailand's 7-Eleven stores and are being considered by US-based fire and safety supply company Tyco."
