Soap making Memes

Time travel paradox meets chemistry frustration! Modern humans dropped into prehistoric times would be CLUELESS about making basic things we take for granted. Soap? That's just fat + ash + water with some saponification magic! Our ancestors figured this out through trial and error thousands of years ago, but most of us couldn't recreate it if our stinky lives depended on it! The desperate face of the modern person surrounded by expectant cave people perfectly captures that "wait, I'm supposed to be the advanced one here" moment. Nothing humbles you faster than realizing your smartphone can't help you make something people mastered before written language existed!
