So, if you want to make a sandwich, you quickly pull out a few ingredients, or go to the grocery store. But, do you think where every ingredient of a sandwich comes from? The YouTube channel How To Make Everything spent 6 months and $1500 to completely make a sandwich from scratch. Including growing his own vegetables, making his own salt from ocean water, milking a cow to make cheese, grinding his own flour from wheat, collecting his own honey, and killing a chicken himself. Enjoy!
