How exactly Moka pots work?
In: 7
Pressurized steam has to go somewhere – its options are either the safety release valve or the nozzle leading to the coffee. Hot liquids and gasses rise but I reckon this would work in zero gravity regardless.
When it cools to liquid on its way up through the coffee and into the top reservoir the back pressure of the steam in the lower reservoir keeps that sweet sweet goodness flowing.
