When I was a kid my buddies and I tried to make "moonshine" from the corn silo runoff. It was bad. I'm talking undrinkable. No worries though, nobody went blind or anything...for it was impossible to keep the stuff down. We would fill a few milk jugs under the silo drain, throw in some yeast, shake up the slurry and let it sit a few weeks. It kinda looked like a gallon of skim milk with cottage cheese in suspension.  I believe we may have missed several very important steps, but what the heck we were only nine or ten at the time:)
