Cities flood. Earthquakes strike. Terrorists foment chaos. If you need to keep it together in a tense environment for a few days, try these tips:
1 For a makeshift club, stack 10 sheets of newspaper. Roll tight, fold in half, reinforce the ends with duct tape. Wet the paper to make it heavier, or add a nail for bonus brutality.
2 Make a gas mask fast: Cut the bottom off an empty plastic jug so it fits over your face. Stick a wet sponge into the hole as a filter, and then seal it up with some tape.
3 Rig up DIY body armor by taping books together with a layer of ceramic tiles on top. Use duct tape to create shoulder straps, and secure it to yourself by wrapping the adhesive horizontally around your torso.
