My Dad was a teenage boy in rural west country England during the war
He was one of the chemistry set generation
constantly experimenting with DIY explosives.

Stories he told me when I was a boy - how much truth or exaggeration I'll never know -

but his two proudest explosive achievements were blowing the door off his mother's oven;

and blowing up an American soldier with a pipe bomb..

His account of that story was
he & his mates were out in a field having difficulty trying to detonate a home made drain-pipe bomb
when a GI stationed at a nearby American military camp
swaggered up the road and said something like..

"here boys, let me show you how to do that properly"...

I presume the yank soldier wouldn't have been that seriously injured..???
