The humble garbage bag doesn't often get the recognition that it's due, probably because of its association with trash and other "worthless" items. Dig a little deeper, though, and you'll see that this plastic pariah has loads of emergency uses. Here are ten of the most important reasons to add a few large trash bags to your survival kit.
1. Shelter roofing: The typical survival shelter has a roof that leaks like a sieve, but place a cut-open trash bag on the roof and you'll achieve far greater waterproofing. Just make sure you bury it under a little vegetation to keep the wind from blowing it away.
2. Rain catch: Lay the bag in a hole in the ground--or a similar low spot--to catch rain water.
3. Ground cloth: Under a tent or other survival shelter, a cut-open trash bag can keep the dampness of the ground from seeping into your bedding.
4. Signal Flag: If you have an orange trash bag, or another colorful option, tie it to a pole and stand it up in an open area to create a signal flag. Tie the bag to the pole in two spots, and it will act like a windsock.
5. Rain Jacket/Windbreaker: While a trash bag isn't much of a shelter on its own, it can serve as a poncho-like covering if you poke a head-sized hole in the bottom and pull it down over your torso.
6. Trail Markers: Cut off small strips of a bag and tie them to brush or branches at eye level. This can create a trail to help you navigate through thick vegetation or in low-light conditions.
7. Cordage: For simple, lightweight tying jobs around camp, trash bags can be cut into strips and tightly twisted into cord. This is not load-bearing rope, but it works for light-duty tasks.
8. Wound Care: Put some snow or ice inside the bag to create a cold compress. Add some duct tape and you can seal off wound dressings to keep them cleaner and drier.
9. Solar Still: Use a clear plastic trash bag as the "greenhouse" plastic for a solar still to collect and process drinking water.
10. Water carrier: Place your bag inside a box, backpack or basket to make a water carrier. Make sure the plastic is several layers thick and not in contact with sharp points. Fix any holes with duct tape.
