I’ve seen a few go off
I wouldn’t mess with them
I had a pal making yet another bomb with black powder in a coffee can
He decided to use a match to peer inside
He’s red faced to this day 50 years later lol
Reminds me of the old grenade toss in basic training in 68. We were in the UUU bunkers. I was in the left one. Trainee in middle tosses grenade, hits the wall in front and no one knew where it went. Sergeant in my bunker turned white (kind of difficult but he did) and it finally went off, just over the barrier. We all got hit by falling scrapple and fortunately no one got hurt. IMO it was not an accident.
When we later got into the two man assault drill, live fire, one supporting the other up the hill, I refused to get near this clown as I was concerned he would “accidently” hit me. The CO pulled him off the line and took his rifle saying he did not want an “accident” on his watch. He got processed through basic anyway.
