Yes,black powder is about $20.00 a pint. Wouldn't take long to go through some money just to split wood. Plus,I guess it has been confirmed that people got hurt badly sometimes using these.
Not only did I help set dynamite a a teenager,there were frequently mercury fulminate blasting caps left laying around from all the land we were clearing all the time. They made dandy firecrackers!! Very dangerous to handle. Powerful enough to blow your fingers off,and mercury smoke to inhale too!! What dandy toys. Fortunately,I knew enough to avoid maiming myself,but I did some dangerous stuff as a kid! Hauling steel cable pulling stumps was another job I did. That stuff can snap tight and ruin you. I knew a guy who that happened to.
