When you're hiking and trekking, one thing you must be able to do in an emergency is get a fire going.
Try some of these hiking standard homemade fire starters on your next hike:
* Cardboard egg carton cups filled with wood shavings and dryer lint, then melted parafin.
* A used film can with cotton balls saturated with vasaline.
* Firestarters used to get a barbecue going
* A butane cigar lighter. (These are like miniature blowtorches that can even get a damp material burning.)
