The lead acetate thing is fun to research, I went down that rabbit hole once, not because I'd ever do it but I like watching other people do it. It is called "the dip" and theres tons of videos saying DONT DO THIS but then showing you how to do it, haha. It turns bright blue or purple, I can't remember... but it's very colorful. Reminds me of the good old days of emerald green which was made of arsenic in the 1920s.
