As someone who has survived two house fires as a child, I've often wondered if having a fire extinguisher, with its sometimes unwieldy in a panic situation firing mechanism, would have helped. Today, there is a much simpler, and quicker solution for such situations.
The Nagekesu SAT 119 throwable fire extinguisher from Japan is possibly the quickest and easiest method of putting out a fire in your home or office. If only Japan had a jumbo version of this invention to cool down its still beleaguered nuclear reactors. The blue chemical housed in an easy-break container costs only $71 here and you can see it in action in the video below.
