And I thought I was a maladjusted delinquent.
We did an experiment in basic chemistry involving flamable gasses mixed with O2 or burned alone. I took that lesson home with me
We had a hang out place that we called "The Bomb Shelter" because it as basically a concrete blockhouse buried into a hill with a skylight and the front door exposed. I bought a dozen butane cylinders for refilling lighters, I grabbed some oven cleaner, tin foil, some newspaper, and a couple of packs of matches.
I used the ket ingredients to construct a nice chemical fuze, then started pulling the valves out of the butane cylinders and pitching them into the bomb shelter.
Just add some water to the fuze, pitch it into the room, run like hell to the next hill over and watch the show.
It knocked the whole front wall out, and dropped half of the roof. Of course we didn't SEE it all happen, because those pussies I was with took off like a shot as soon as fire started shooting out of the roof.
