Outwitting HMC&E (that was) !
Some time ago on this Thread there was a discussion on the various nefarious ways in which the red dye could be taken out of red diesel and petrol, so that you could run road vehicles cheaply (illegally) on it without much fear of having "your collar felt".
On "Yesterday" Channel (19) 18.8.15., on "Wartime Farm" (1100), there was an incredible demonstration of a method I had never heard of before. A 800 gm loaf of bread was upended, a hollow dug in the end, red petrol poured into this dribbled out the other end gin-clear.
I don't think the programme was a "spoof". Anybody else heard of this (or is prepared to try it ?
