At least one idiot ( sorry politician ) has tried to say the model rocket guys could produce a guided missile! Getting hold of the higher powered rocket engines in UK is difficult. With some thinking and a bit of fiddling quite effective pyrotechnic effects can be manufactured HOWEVER its your eyes and hands that are at risk if you try it.

Calm down guys! 😲
I was only tongue in cheek musing about a miniature cruise missile since we were into Jetex etc.
If we're not careful we'll get the NSA on our necks 😡

As I thought 👍

leaving aside the fact that nitromethane is not nice stuff to have around in an undiluted form I cannot see adding it to glycerine making anything like an explosive in fact the nitromethane is an explosive ( potentially) all on its own.
