LOL, we ALL did that! I remember breaking into an old abandoned building on the base, and ripping off a huge section of asbestos covering from around some pipes and throwing it against the wall...it would explode in a huge cloud of white asbestos dust, and be covered all over with it (probably breathing it in, too)
I also remember my brother found a small bottle of mercury (probably about 200ml) and he brought it home and we would pour it on the floor and into our hands...scoop it up with a sheet of paper and pour it back into the bottle when we were done. (to this day, me and my brother both have elevated liver functions and have had our whole adult life...probably caused by something like that)
But what are you gonna do? Such is the stupidity or ignorance of youth!
Preach it, Brother!
