>>12294702soapmaking is pretty enjoyable actually. cold process is less "labor intensive" but blending olive oil and KOH, cooking it, and actually watching it turn from "food" into something you can actually bathe with is neat.
another neat phenomenon is anything with anthocyanin. i eat a lot of frozen blueberries, and if you eat them out of a glass, you are left with a small pool of dark purple dye. add a bit of water and it's clearly blue. drop in a bit of vinegar and it flashes to pink. trivial and kind of dumb, but i've shown it to a couple people just coincidentally after eating blueberries, and they go "wow that's neat!" if you explain the process as you do it.
anything which is like, "chemistry from nothing" is interesting to people i think.
i'm also doing this from the perspective of like, children. if you mean "what chemistry stuff can i do at home without having to get a bunch of glassware", the answer is actually a lot of stuff. you could probably do aspirin => methyl salicylate with stuff you have in your kitchen.
