Reader Tip: Double-Duty Firestarter

All you need is toilet paper and a little olive oil.

I have the easiest, lightest way to start a fire—using stuff that I take on a hike for obvious reasons. Loosely ball up five squares of TP and shape into a bowl. Pour a small amount of olive oil in the bowl. Crush TP into a ball, saturate the outside with more oil, then place on tinder and light. The flame will last more than five minutes.
