I admit to trying foolish things, just because........now that I'm older and realize I'm not 10 feet tall and bullet proof, I'm also a lot more careful. The Good Lord must have had guardian angels on special duty to get me to adulthood.
We once decided to make a bomb underneath an abandoned concrete slab of an old cabin on the river. A short length of cannon fuse, some black powder, a cigarette timer. We got in the boat and crossed the river and waited almost forever it seemed. After determining that the cigarette must have gone out, we started back across. We (my brothers and I), were about 150 feet away when the slab lifted up in three great pieces and overturned. The concussion was enough to almost knock us down.
Like I said, my angel worked overtime until I was in my 20's.
Don't think safety glasses would have been enough for that one if we had been a tad closer....
