Hrm. I guess it depends on what type of "useful home chemistry" we're talking about.
Are we talking cleaning-with-baking-soda-and-vingegar level? Foods that change color vs. different pHs? Flavor chemistry? Ferrofluid? Tie-dye? Fluorescent uranium glass?
My first instinct was to just answer google / duckduckgo, because I generally start there, but probably being a specialist in the field makes it a lot easier to sort through results on a case by case basis...
