Okay another question, how do I dispose of an unspent rocket engine containing gunpowder? Any rules re this, it is damaged so cant be used thanks Maria
Small quantities, not exceeding 25 kilograms on any one occasion, of blasting powder or other nitrate mixtures (including a mixture of ammonium nitrate and fuel oil) may be rendered harmless by immersing them in water, bagging then disposing of into the garbage or incinerator if available.

I have some model rocket engines that came with the instructions:Do not use damaged model rocket engines. Soak them in water for a day or two until they come apart, then put the remnants in the bin outside.
Sounds easier than trying to get the powder out!

Love your idea Smiley but only a temp and hoping for further work next year!!!!! Thanks all for the advice I had thought of soaking it in water, I dont want to keep it just dispose of it safely so shall follow your instructions Cheers Maria
You could try igniting it under an upturned wheely-bin? Listen for 2ndry ignition.
We've fired rockets horizontally at a mannequin's head positioned inside a wheely-bin on its side. Testing PPE you know; the mannequin was wearing safety goggles.
