Sourcing the potassium nitrate and sulfur was no problem in the '50s but 
trying to grind down charcoal was a miserable task. During one of the 
times in grade school chemistry class when I wasn't daydreaming I learned 
the formula for sucrose was C12H22O11.  Hmmm, that looks like a lot of 
carbon and stuff that should turn into water vapor. Rocket candy was born!

It was many years later I found out about it. It wasn't much of an 
explosive but back then dry gas came in about a 12 ounce can with a 
conical top that necked down to a screw cap. Filling one of those and 
lighting it lead to a very satisfactory fountain of flame. I never thought 
to try launching a rocket with it.
