British Standard [tm] mineral water from most places is not liable to be too too unsuitable. Evian on down. Advice aimed at people who are not likely to think that flavor, coloring, minerals etc can be included and have the product still count as water in this context. // I recently used coffee with milk added to "clean" something 'in the field' as I deemed the likely result to be superior to not doing it. It did the desired job. I'd not recommend that mixture for most cleaning purposes :-). | |

Boil water once, leave to cool somewhat, boil again. In the "right" circumstances the water will "explode" out of its container when moved or when eg coffee powder is added. The original air added nucleation sites for boiling initiation which are now absent. Success is dependant on container snoothness, otther contaminants and some "luck". I have NEVER been able to cause this to happen despite trying on various occasions but i is widely reported. | |

Boiling water will drive out dissolved air. ... | |
