This clip is from the old Australian soap opera Prisoner (Prisoner: Cell Block H), in it Lou (short for Louise) the bad guy prisoner is selling Jan (a lawyer who is also a prisoner and co-incidently an alcoholic) a drink.
Now it looks like Lou is handing Jan a bottle of rubbing alcohol, but maybe I’m wrong.
Lou’s recipe seems to be
Rubbing alcohol, water and liver salts (whatever they are) all mixed together (1:00)
And she calls this Bush Champagne. (Bush as in the Australian Bush)
Around 1:08 Jan complains Lou is charging her $5.00 for “this” and Lou says that it is only for the “metho”
Later episodes find the others refering to Lou still selling meths to Jan.
Since this is in the early 80s and a drink it’s obviously not the same as meth, the drug is now? Or is it?
