The big pot is a samovar. Tube runs thru the middle holds solid fuel, heats water. To get a draft, traditionally you used a jackboot as a bellows. After water got real hot, pull out the fuel chamber, put a teapot of REALLY strong tea in its place to steep. Dilute STRONG tea with hot water from samovar. Add vodka to taste- and THAT will make you stutter!
What we have here is... failure- to communicate.
