: Touching a 9V battery to fine-grade steel wool causes the metal fibers to glow white-hot instantly, making it a reliable fire starter even in damp conditions.
Maintaining core body temperature is the highest priority in extreme cold or heat.10. : If you have access to packing materials, bubble wrap is an incredible insulator. Wrapping it around your torso beneath your clothes traps air pockets, providing significant warmth.11.
