I was gonna try and patent this process using a powderd aluminium cartridge but a mist of caustic soda is simply to dangerous for the general public. if the mist got in your eyes you'ld be blind and if you were to breath in the mist you'ld be dead
the mist coming from the humidifier has no preasure behind it so I had to add a diaphram pump to force the mist through the aluminium powder.
Oof... Please be careful! Also remember that reaction will be thermobaric, so make sure that your mixing container can handle it.
