One dark night donkeys years ago.......err 1976? somewhere, cannot remember, I was settling down for the short night<br>under the front, adjacent to the axle, of a Bedford RL. I thought that I would make a brew of tea on the Hexamine burner.<br>In those days I took sugar in my tea, it was pitch black apart from the flame under the mess tin and so it came to pass in the cramped conditions that the white substance that I thought was sugar was in fact part of a Hexy block.<br>My tea ruined and curses into the night............Try it if you have a Hexy block, just for the fun!
