Oh, a still is EASY! All you'd need is something to cap the top of whatever vessel you're heating, and a length of tubing (preferably glass). Make sure the tubing is long enough, and has a lot of coils in it -- the distilling occurs when the steam generated by the boiling condenses inside the tube, then drips out the end into the collection vessel.
Ah, memories of Organic Chem class. Good times, good times. (Not.)
