Talk:No 7 Mk1 Dingbat mine

What's inside these things?
I remember being taught to lay the Dingbat about 30 years ago, and our instructor telling us that originally they had contained glass, the idea being that the glass shards would enter the bloodstream and be transported to the heart, which they would then puncture. "Unfortunately," however, glass has the "disadvantage" of showing up on x-rays, which meant there was a "risk" that a surgeon might be able to remove them before they could do their job. Can anyone confirm/refute this and, if so, add a couple of lines on the topic? [Articles have to be NPOV, talk entries do not. Mine isn't. My ideas have developed over the last 30 years :-)] --UrsusMaximus (talk) 19:19, 26 December 2007 (UTC)
