Just dissolve some concentrated colour in water or just take some strong smelling solution & put these in clear glass bottles. After some time empty the bottles & wash. Just see whether glass looks somewhat cloured or smell something.
Kumar, do you never drink something out of a reusable bottle? Do you use a new cup each time you drink tea? Do you throw away a dinner-plate if food has been left on it and become putrid?
No?
No, you wash it (or somebody washes it for you
). Does it become clean when properly washed? Yes, it does; you can fill a glass vial with monkey-[feacal matter] (edited to defeat nanny-bot) and leave it in a warm place for a month (
), and it can be made absolutely clean and sterile again.
Just test remedies & bottles, for presence of molecules of active substances in any remedy or in any bottle in which potentisation was done. Does science not yet has this testing technology?
Of course science has. There are several methods; purity of solvents and compounds is an important parameter, not only in research, but in industry.
Homeopathy shows this presence 'as effect of remedies'.
No, it does not. NOBODY, not even homeopaths, have been able to provide proof for "effect of remedies". Don't you understand ANYTHING of these debates? This is exactly the whole point: Nobody can show that remedies work
.
