- I was awakened one night by an blast that shook the windows of my house.
- A short time later I saw a number of emergency vehicles and walked down
- the road to see what had happened. It turned out that someone had
- dropped a 1 lb. can of black powder on a concrete garage floor, and it
- exploded. All the windows were blown out of the garage, and the guy
- that dropped the can was seriously injured.
