Water pipes have been compromised and things are looking a little… brown?
Fill up a glass with the dirty water, and place it beside an empty glass. Roll up a piece of cloth. Put one end of the cloth into the dirty water and one end into the empty glass. Let sit. Eventually, clear water will absorb into the cloth and drip into the empty glass.
12. Mouse Traps + Glow Sticks = Alarm System
Worried someone has been trespassing on your post-apocalyptic property?
If you have a mouse trap, a glow stick, and some string, you can build your own alarm system. Place the glow stick on the base of the mouse trap, and attach the string to the mouse trap’s trigger. Pull the string tight across the door. If the door is opened, the mouse trap will trigger, and hit the glow stick. A lit glow stick will prove someone tried to break in.
