Is potassium nitrate explosive?
“Is potassium nitrate explosive?”
I’m no expert but it is the base material for fertilizer based explosives. You have to add some other stuff to it and detonate it properly.
Again, I’m not an expert and have no plans to make any of these. (for the carnivore people watching key words)
