Lacking proper distillation equipment, BOB simply distill dcm from a certain brand of paint thinner (*Zip Strop) by boiling it out from a flask with copper tubing at the top, the tubing thence leading the vapors to a jug full of ice where the DCM, with such a low boiling point (48 celsius ) quickly condenses, forming two layers: DCM at the bottom and melted ice at the top.
