My 6 Year old granddaughter asked why witches wear pointy hats

22. One of my fave YT channels is Tasting History

The guy finds an old recipe, recreates it, and taste-tests it while giving a history lesson about the dish/time period. I recently watched one about a stew that dealt with the differences between inns, taverns, and alehouses, and he mentioned that it was often women running alehouses, which were just out of their own homes, and he talked about their hanging up a long stick over their doors to show they were open. He didn't tie it to witches though.
