As clar8ter says- charcoal (or sugar) is the fuel. Nitrates are the oxidizer. Sulfur lowers ignition temp.
St. Barbara (patron saint of those that fool with explosives and artillery) is busy enough- do not increase her work load.
If you must experiment please do so where (A) your demise will not harm your neighbors, and (b) it will be easy for the folks with the firehoses to flush the bloody pulp off the walls, ceiling, etc.
I was visiting a major explosives making company- can't name names, but sort of THE explosives maker. As you get closer to the point of operation, the man-loading (number of people allowed in an area) drops off. At the final point, there is a place that you remove your ID, and leave it at that place before entering.
In a very bad event, they will know who was in what is now a large smoking hole in the ground. And THAT is with a well run, professional operation that follows established safety practices.
Think about THAT before dragging out the Anarchist's Cookbook.
What we have here is... failure- to communicate.
