According to the news, the bombs used in London were constructed from chemicals obtainable from high street Chemists.
Well, of late I've tried to get stuff like ammonia for cleaning and, more optomistically, dilute HCL for de-scaling and just got a look of bemusement from behind the counter. I came to the conclusion that the old fashioned Chemist doesn't exist any more -they are now Pharamacies selling drugs, cold cures and the like but not household chemicals.
Does some Chemists actually still sell old-fashioned cleaning agents, meths, paraffin, ammonia and the like thesedays?.
