SD, When I was a National Service man, I was on a Jungle warfare course and part of this was improvised explosives. We were shown how dangerous it could be and were told only do it when absolutely necessary. There are many formulae out there, many of which are very dangerous, made up by people with infantile minds. To sort out the best from the bad, you can use Army manuals, they are still dangerous. If you do try these formulae, only make very small batches. Of course, many years have gone by since my youth and I would be looking for up-to-date instruction from NR and BP. Kenneth Eames.
