as a child we had a stim of putting our fingers in our mouth, up until we were like, 12, so we have definitely consumed the remnants of things like cleaning products and whatnot. but actually eaten is different, i'd say maybe HJ-7, one of our hosts own concoctions. it is similar to the tiktok "battery acid" drink, but with a specific recipe and made to be as smooth as possible- no random candies floating around. For awhile we allowed it once a month, since we knew how awful it was we were trying to reign it in, and then our dentist said our front teeth were "melted" and we decided that was enough of that. Only had it a handful of times since, for special occasions.
