Yeah, it's very contrived. I've lost friends for sharing this opinion as well.

I think that was potassium-permanganate and sugar. It was one of the saner recipes ( who really wants to blow their face off or smoke banana skins ) with somewhat easily available ingredients. It was legit. But the temperature window between melting the ingredients together and igniting it was very narrow. We did what your friend did, we made the smoke bomb and also set it off in one go. Your friend must’ve been in a while ton of shit.
