Yes, Sue, there are some of us who are that crazy, at least used to be, before the "S" got ripped off my chest a couple times. Now I guess I know better. We've built several such IEDs in my youth, but were always at least smart enough to take them out to the dunes far, far away from anyone else and set them off. If the detonating charge didn't do the job, then a well placed AP round would usually do the trick.
We were lucky, and didn't have to learn the hard way, but there were more than a few times I shoulda been blown to smithereens. I can't believe I still have all my fingers, both my eyes, and can still hear reasonably well. God watches over fools sometimes I guess. Blast may be able to attest to this fact better than I.
Of course, none of my creations came anywhere near the sort of explosive demonstrations I got to see in Baghdad. Truly awe inspiring.
I think the biggest explosion we ever came up with was a cratering charge used to make tank traps. That was probably too much for us to be messing with, but that was in the day when you could buy a 50 lb bag of High Nitro fertilizer and a couple gallons of diesel. The hard part was coming up with an adequate detonator. Boy, did that make a hole, though. I think that was bigger than the Tovex/Dynamite blast we did out in the Nevada desert.
