—about 1949 (when I was 8) my sister an dI went to a nearby rock quarry and brought home some wood dynamite boxes from the scrap pile—never found any caps but finally figured out we were getting nitroglycerin headaches from using them as toy furniture——sure wish I still had the boxes—they are worth a good price now-—
Back in 1961 my dad brought home the plastic bags used for dynamite. I still remember the smell. Mom would rinse them out and we would use them to carry our laundry to the Laundromat. Never got any headaches but I do remember this was well before plastic bags came into common use for trash. The bags were real heavy duty!
