If you can come up with a cheap way to build a still though, share how so I can have my very own fuel (sic) lab.
Four words ... Stainless Steel Pressure Cooker. Cheap as in "Garage Sale Cheap". Or just buy one.
Stare at it until the obvious comes to you. There is a thingy it will come with that you can put in a drawer until someone wants to actually cook with it. One fairly important part goes where the thingy is supposed to go, and there is another hole in the top.
You use that other hole for a thermometer.
And in case you ignore specific details I'll spell it out for you ... do not use an Aluminum Pressure Cooker.
