The term 'moonshine machine' refers to a STILL, which is an apparatus used to distill alcoholic beverages. A STILL typically consists of a pot, a condenser, and a receiver, and is used to separate the components of a liquid mixture by heating it to the point of evaporation. The vaporized liquid is then condensed back into a liquid form, resulting in a higher concentration of alcohol. Moonshine machines have been used for centuries to produce homemade liquor, and are STILL popular today.
