nucleation
creating a low-cost (maybe a no-cost), but high efficient extinguisher - by using popular science
Description
"a fire-exstinguisher as complex as a drinking-bottle"... using a simple chemical/physical reaction to create a exstinguisher everyone should be able to use - made of things can be found in every household! the principle is well known from the "coke-mentos-eruption", shown on a popular tv-show and on many youtube-videos. some of these experiments create sprinklers - the inspiration to the idea. the beginning of the idea for a real frugal innovation. * the function and the chemistry/physics behind is simple - it´s just about the expansion of gas (CO2) and the displacement of fluid. beside this, the variants of use are diverse: the new bottle-extinguisher can be thrown, placed or holded, in relevance to the fire. it should be easy to learn the handling of the different variants and it makes fun to try it out. it´s cheap, robust, easy and can be used by everyone. * the idea started with a funny experiment - now it safe lives. *** for better understanding, please check out the www-pages and attachements. further (small-budget-)development would include tests (best sprinkle-pattern, handling, chemical ingredients), 3-D-print of nozzles, life-test with fireman and then users
