Tundra's Fire Extinguishing Spray is a simple idea. Lose the bulky fire extinguisher and use a spray can instead. Aside from convenience and portability, the Tundra spray has some other advantages: The spray lasts four times longer than even a large extinguisher's burst (this could, though, be because the spray comes out slower). The nozzle also disperses the spray over a wider area.
The one problem, though, is a psychological one. We all know you should never spray an aerosol onto a fire (except for dangerous teenage pranks). Could that lead to hesitation in putting out a fire, or even flat out refusal to use the device? $30.
