leaving! Her face and hands looked very brown to me1 perhaps my explosive had dried out properly over night!

I found GunPowder was a lot more difficult to manufacture than I had expected from the reference books available to me. I knew I had the mix right but was unable and too impatient to mill it to the right consistency. I used most of the Gun powder mix I made for my rocket motors and when I required star explosions or other explosive I had to fell back on Potassium Chlorate and Sulphur which would detonate easily.

Such a mix could be filled into small bag mounted outside the base of empty cannon shell case the shell case was filled with some sand and the end was plugged using a short stick cut to hold a cardboard tail. When this shell was thrown against anything hard the head would explode with a load bang. Our house in Harrow Weald was pebbling dashed, at least it was but it lost a lot of pebbles during my tests for I used the wall for my test area.
