Still
A still is a tool used to distill miscible liquids by heating and then cooling. Invented around 10th century, it has been used to produce perfurme and medicine and most famously, to produce alcohol using fruit juice.
Since alcohol boils at a lower temperature than water, the result is a strong alcoholic drink. Usually a still is made of copper as it does not give taste to the drink, resists acid and conducts heat.
