I recall in middle or high school making ammonium tri-iodide with a friend whose dad was a navy seal and knew a thing or two about explosives but nevertheless for some reason thought it was ok for us to make a highly touch-sensitive explosive without supervision. We got the instructions from some variant of the Anarchist Cookbook, and they quite simply instruct you to dissolve iodine crystals in ammonia and filter it, leaving behind a residue of the product. We left it inside a plastic cooler outside for the ammonia to evaporate, which was fine until a gust of wind caused it to detonate and blow up the cooler. I don’t recall us having a plan for how to get the filter out of the cooler without detonating it though, so I’m grateful that it blew up when we weren’t nearby.
