But I've never really had much of an interest in explosives or pyrotechnics in general. They're fiddly, rather difficult to obtain materials for, and almost invariably illegal. It's not that I lack the capacity to understand them, only the will to learn about them.

And clide, you can't get evidence much more concrete than that...

The majority of individuals here know the absolute basics of spudding; How piston valves work, how to construct a pressure vessel, how to solvent weld, how to build a breech loading setup, the absolute basic operating principles of combustion launchers ("Use online calculator to find fuel meter pressure, put pressure in meter, put fuel in chamber, ignite, potato flies out of the barrel"), pneumatic launchers ("Pressurize air chamber, open pilot valve, pressure vents from pilot chamber, chamber pressure opens valve, air pushes projectile out of the barrel"), and hybrid launchers ("Put excess fuel in chamber, add air pressure to balance the ratio, ignite; pressure rise ruptures burst disk, projectile flies out barrel"), and some grade 8 level mathematics formulas that allow them to figure out volume ratios. These are the people who direct my vote towards NO.

To succeed in the manufacture of high explosives or relatively unstable pyrotechnic compositions, you really need to have a sound knowledge of chemistry, or you will be maimed or killed. To succeed in basic spudding, you are simply required to know that "Pipe is glued into fitting, pipe has certain pressure limit, valve is actuated, projectile shoots out barrel". The consequences of idiocy are far smaller, the materials far more readily available, and the construction and basic understanding much simpler.
