No, I’m not planning on trying any of this at home, but I’m curious…
A friend of mine told me a story once about another friend of his who, instead swallowing aspirin for a headache, crushed some aspirin tablets, dissolved them in water, and injected the solution straight into his vein. Now, I’m not completely sure this actually happened, but I can’t think of a reason it wouldn’t work.
On a slightly different note, instead of boiling water to sterilize it, could you instead add some (very small) amount of chlorine bleach to it? A couple of drops to the gallon, perhaps?
