Consumers may soon be able to go for longer between milk-buying trips. That's because Brazilian company Agrindus hopes to start marketing plastic milk bottles that use embedded silver nanoparticles to kill bacteria. Grade A pasteurized fresh whole milk packaged in those bottles can reportedly last for up to 15 days, as opposed to the usual seven.
The technology was developed by partner company Nanox, and involves first coating silica ceramic particles with silver nanoparticles. This reportedly has a synergistic effect, with the silica boosting the antimicrobial properties of the silver.
Those coated particles take the form of a powder that is subsequently mixed into liquid polyethylene. Using blow- or injection-molding, that plastic is then made into bottles which Agrindus plans to sell to dairy goods companies. The particles can also be used to make milk bags, which should extend shelf life from four to 10 days.

Thanks... what you described is exactly what went down.
I am older and wiser now, but in my youth I did many an asinine thing. Fortunately lived to tell about it.
I guess the most terrible thing is with as much experience as I have acquired, I *still* do quite asinine things from time to time.
Usually not nearly as dangerous, but every bit as destructive and wasteful of resources.
Not intentionally, but as a result of a failed attempt to do something.
