Do It Yourself Rocket Engines

I am really keen on rockets, propellants and explosives - for legit issues like space launches, demolition, quarry work and shaping metal etc.. BUT it's all the stuff I don't know, that comes from people and places blowing themselves into bits or into orbit - that I don't have and don't know.... https://www.youtube.com/result....s?search_query=ammon ------- The legenday Pepcon explosion. https://www.youtube.com/watch?v=_KuGizBjDXo long full version https://www.youtube.com/watch?v=gGSx54CkWsQ and then there is the sort of things that kids do.... just to see what it goes like.... https://www.youtube.com/watch?v=Nl6XvznIrHc ---------- So there is a real difference between 6 million pounds of propellant going "pow" and say, 500 grams, 5 Kg, 50 Kg or 500 Kg or even 5000 Kg in space rated rockets... going up.. by exploding in your face or in the same building etc.. and Pepcon... but it's all the same... If you get it wrong - dead is still dead. So I am all for totally going for this, but SAFELY and successfully... AND with some of the things you don't know that will kill you, he doesn't mention, like only using wooden stirrers to mix the melting mixture, and SAFE upper temperature limits for the mixture, and the differences between a flash fire - or rapid combustion and an explosion...
