You are in a room with 3 switch which control 3 lightbulbs in the other room. There is no window and there is 1 door. You can only go in the other room one time and once you open the door you must go in and the door will close behind you. You must find out which switch controls which lightbulb...
It dawned on me this morning in the shower as I cracked a Stone IPA; do zombies poop? They are dead and have no bodily control however they eat flesh and other stuff so how do they remove the waste? Or do they have waste?
Get a hydrometer. They're like 8 bucks at your LHBS (local home brew store). It'll help you track the progress of your beer, let you know when it's time to bottle and the ABV
I keep mine in my closet, it's dark quiet and a consistent temperature. As long as it doesn't get too warm where your beer is you'll be alright. I refrigerate mine as I want them but everyone has their own way of doing it
