well... once the sweet corn has dried you'll need equal weight of sugar, a very large barrel, plenty of clean water, and some yeast
Let that kick off for a few days until it stops making a foamy mess anyway.
siphon off the liquid into a stainless pot with a set of condensating apparatus, and cook it as 140-170 deg (3 different heats work good...)
then bottle the clear liquid in what ever glass containers are cheap and plenty full... mason pints and quarts are a good start, though I've seen folks use plastic kerosene jugs....
Oh wait... this is about masked furry bandits, give them a drink too, then share all the cats food, but leave some water out so they can warsh their mitts
OR your electric fence needs a deeper or multiple grounds, with a bigger power unit, and be diligent about keeping weeds away from the line, anything touching said wire will ground it out, weakening the charge.
But mostly share the clear liquid with the masked marauders (there is a few fairly important steps missing... just don't use any lead solder, salt dough for making seals... copper is fine but stainless lasts longer, and make sure everything is clean please)
