A few of mine and some from the web... 1. When camping or just in a SHTF situation where there is no electricity, a standard headlamp strapped to a 1 gallon plastic milk jug filled with water can light an entire room or tent. 2. You can use AAA batteries in electronics that call for AA batteries by filling the gaps with folded up aluminum foil. the operate time won’t be as long as with AA's but, it could get you by in a pinch. 3. A space blanket (one with an aluminum reflective surface) can be set up on the opposite side of your campfire to reflect heat back toward you. It also serves as a wind break. 4. A 55 gallon Black Plastic contractors trash bag makes a great emergency poncho. remember when venturing out into the wilderness to always have a water proof hat. One of the roll up hats from Outdoor Research are perfect. Outdoor Research | Hats: Warm Hats, Winter Hats, Sun Hats, Rain Hats | Outdoor Research | Designed By Adventure | Outdoor Clothing & Gear 5. An empty Altoids tin makes a nice storage container for your dry fire starter, char cloth, flint and steel. Got a Tip, Trick or Tweak.... Feel free to add on.
