James Vincent, The Verge, translated the technical challenges involved in rocket fuel into plain talk: "It's potent and volatile, meaning it can explode before it even gets into the rocket. That makes manufacturing it tricky, as you need to mix together certain materials, but fling them around too hard and they'll start doing their job early." (Evan Ackerman in IEEE Spectrum similarly noted, "when you're mixing up something designed to be more or less as explosive as possible, you want to do it very, very gently.")

This research claims to be safer in the mixing of the ingredients is done in a gentler fashion. For those who have made APCP propellant, is this the most dangerous aspect of the process of making your own propellant? What is regarded as the most dangerous aspect of making APCP?

I'm no expert, but this looks like a great way to ensure lots of entrained air and inconsistent mixing.

By far the most dangerous part of mixing propellant is the drive to work.

Maybe if one lives in greater Phoenix.
Not if you just have to walk out to the shed.
