No details on the mixture that was used.

The "rocket sounds like a galvanized pipe,...maybe threaded at both ends with screw on caps.
small hole in one of those caps for the ignition of the " rocket fuel".

If the fuel is "loose", or hole is too small or gets plugged, then the rocket becomes very dangerous.

Our Elementary School "Show and Tell" classes, we used only Commercial Model rocket engines, and the class was protected by thick LEXAN Blast shield.
Never attempt making your own rocket fuel,....trace contamination has been known to speed things up a little bit.

Does anyone have any further details on this? I am curious as to the formulation of the fuel. We have a project starting up in preparation for a 2018 competition that will require formulation testing.
