Your comment about the shells brings back a memory. ?As a youth probably in early bot scouts we made a visit to the sheriffs office for a tour. After being shown all the armaments available to them the officer gave each of us an empty rifle shell¡¡ later I was heating something in my chemistry set using the shell as a test tube¡¡ and BANG! ?the shell still had the primer left in it. ?The primer blew out and broke some glass in my chemistry set but no harm to me. ?My mother wasn¡¯t home so I got away with that one¡.. alive. ?Some of us do have a guardian angel.
