In my childhood, one object drew my attention much by its smell! Even at these present days I could smell and detect its presence in any other materials that had contact with it: we can detect it by its characteristic aromatic odour - even when this odour is present in its lowest concentration! This object is white and round; and is commonly seen in households. It is nothing but our Mothball. Its content chemical is either Naphthalene or Para-dichlorobenzene. Its Tamil names are 'Mannenaikundu', 'Patchaa urundai', 'Anthurundai'.
