Rocket Engine

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

I would kept for collection. Gunpowder, how on earth did you manage to get that.

Wait for a school camp, chuck it in the campfire and run like hell!

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!

I thought maybe they wanted to keep the body intact for display - minus the powder.

No worries, Richard

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.
