Rocket engine assembly

Hallo fellow rocket enginers,this is a tool set to make your own small 18mm rocket engines. Just grab an 60mm long 5mm steel rod and an used elfbar vape.You can create the boddies of the engine by folding some paper around the vape. Then dip the rolled paper in an wood glue water solution and let it dry.The paper tube will fit over the nozzle maker and you can dump aound 3.5gram of clay into it. Then stump it down with the compression rod. Add 8 gram of the rocket fuel (kno3@65% sugar@35%) and compress it. Seal it by adding an other 3gram.Your engine is ready and this in under 15 minutes with some good precision to replicate them in performance.BUT BE CAREFUL YOU ARE DEALING WITH EXPLOSIV SUBTANCES.
