For those looking for the "Cilffs Notes" summary of how this works: Fill a 4-foot polycarbonate tube with approximately 1lb of (12x40 mesh size) Activated Carbon (activated charcoal), put a couple coffee filters over the end, pour the alcohol into the top, and watch as your cheap swill magically transforms into decent, respectable booze.
