But you know what dental floss is, right? The string you push between your teeth? What do you call it over there? Granted, England isn't known for their dental care but surely you must have a word for it. This machine does the same job, but better.
I'm no more English than the Pope or JFK. The current avatar should be the clue there.. I do stay slightly to the English side of the border (but about 50 miles North of Hadrian's Wall) much of the time but that's only because it's handier for road links to more of the campuses I work in than my place on the Scottish side, which is simply a but 'n' ben that allows me to maintain voting rights in the nation of my birth. As for dental floss, I have now looked that up , I'll stick with the brush for the time being.
