When I was a kid, my parents' old Mr. Coffee broke. Because money was tight, it wasn't replaced for some time. I remember waking up one morning and finding my mom making a cup for herself by perching the brew basket from the broken maker over a mug and pouring boiling water from a kettle.
For me, seeing this bit of kitchen MacGuyvering became a truly paradigm-shattering moments. Until then, I thought coffee required an electric drip machine — that it was the only way coffee could be made at all. But seeing this patient pouring of water over grounds, it became clear that the machine wasn't necessary. Some things you really can make yourself.
