NOTE:
this fake-still design is NOT recommended.
It is much better to design and produce and use a REAL still
The Solar Still - Air Stripping
Yet another technique is to strip the alcohol from the wash using air bubbles. A smaller
bucket of wash is put inside a larger bucket, with an airstone (like that used in a fish aquarium)
bubbling small bubbles up through the wash. The vapour will strip some alcohol out from the wash,
and it will condense on the walls of the outer container. I suspect that a fair amount gets lost too - as
some air will always be exiting the setup. Maybe you'd arrange it so that the air intake to the pump
was inside the buckets, so that you were just recycling the same air.
