My totally legitimate, absolutely legal, perfectly safe alcohol still I made out of a pressure cooker, a tin can, some Ceramic Raschig rings, some copper pipings, silicone tubes, 3 lion batteries, a fishtank pump and a pc radiator. A lot of soldering were involved.
It has a fractioning column and a condenser and this thing actually works pretty well.
Yes, it is legal to own a still. Yes, I use my engineering knowledge and skill sets to build sketchy shit now and then.
