OK, how dumb were my mates and I? We "aquired" some smokeless powder and some magnesium tape. We had been punching holes in the side of 6mm Rem cartriges after removing the bullet, toppin them up with more smokeless, crushing and folding over the necks and then sticking the magnesium tape in the hole in the side for a fuse. We were performing "experiments" by putting these small pipe bombs in and old ammo tin we had found with various items like plastic soldiers, match box cars, etc. The ammo tin was strong enough to contain the explosion and we could check out what the boom did to the toys. We then found an old section of bicycle seat pole. We were smart enough to know that if the little ones were good, then the bicycles seat pole would be GREAT. We were not smart enough to know that the pipe bomb would be just a little too much for the ammo tin. We filled it with smokeless powder and some BB to fill up the remaining air space. The moment it went BOOOOOM!!!!!!!!!!! I knew it was too much (we were in an urban back yard, not out in the bush). I started running for the shed. As I was running to the shed, I saw the lid of the ammo tin falling out of the sky, trailing smoke. My mates that I had been with had seen it go up and they thought it went about 100 feet up. As I sat in the shed, shaking with fear, the next door neighbour put his head in the window of the shed and said something like "Well that was smart, wasn't it." I looked at him with my most innocent face and said "What?" I am fairly well convinced that the neighbour thought I was retarded, that was the look on his face, anyway. Anyway, I thought things couldn't get worse, untill I looked up the driveway and saw my mum walking down towards me. My house was about 4 doors away and apparently the BOOOOOOM was big enough that it rattled the windows in our house. Now just to recap, the explosion was heard about 1 km away (my dad was at the club having a few drinks and he heard it over the juke box), the back yard was full of smoke and fragmented ammo can, the next door neighbour had seen what we did and all the other neighbours in the area were out in the street saying that they had heard stuff falling on their roof, and I thought that I might still be able to get out of this by playing innocent and denying everthing. Damn I was stupid.
