Activated Charcoal powder is a must for all first aid kits and medicine cabinets. its drawing activity is second to none, and it is super fun to play with in cosmetic and food applications, as nothing else you’ve ever seen is as gloriously, extraordinarily BLACK as this is (and while this may be obvious to some of you, its quite a surprise to others, so I’ll tell you right now: if you ingest lots of charcoal, your poop will be black as midnight). Comes with a warning that it will turn everything it touches black, too.
