Like that stuff would have been stable! Idiots...
A couple of years ago I was digging through a box of stuff in my father's old shop (he's since passed) when I pulled out a live 20mm cannon shell! He'd brought it home years and years before. After VERY carefully setting it down on a nice, thick piece of carpet I got a hold of a friend of mine who had some old wells to cement in so the next day we dropped it (backwards!) down an old piece of casing, RAN AWAY, came back after nothing happened, and pumped a couple thousand pounds of concrete down the hole on top of it.
