In Mr. Pikkaranien's junior chemistry class, for the term research project, making a still from glass tubing and brewing a truly vile vodka from potatoes. Don't know how often they let kids do that anymore! In another chem class, making small explosives out of potassium iodide and tapioca that you could pocket around and drop surreptitiously in the halls to make gunshot sounds with purple smoke. Yet another fun science activity that would surely get you arrested today.
