I know that’s a stretch but there’s a reason why you need aluminum foil in your survival kit or B.O.B.
Here are some simple, but essential uses of tin foil in a survival situation.
1. Drying your tinder
If you’ve ever had a hell of a time getting your tinder to light, you’ll appreciate this trick. You can dry your tinder by putting your tin foil on the ground in direct sunlight.
Then place your tinder on top and a one gallon ziplock bag on top of the tinder. The sun will heat the foil and tinder and cause the moisture to evaporate. Flip over the ziplock bag every few minutes so the condensation doesn’t soak back into the tinder. As you can see, I used grass in this photo but it works with all types of tinder.
Note: the photo above shows a mylar blanket but it is no different to replace it with the foil.
2. Temporary battery replacement
If you’re missing a battery or one is dead, you can still use your flashlight. Just roll up the foil in the shape of a battery and stick in in there. If you don’t believe me, I show you how to do it on my post Power a Flashlight With One Batter.
3. Secure batteries in place
Much like the tip above, sometimes the springs in flashlights (or other electronic devices) break off or lose their ability to hold the battery in place. Fold up a little tin foil to keep it in place and provide conduit for electricity.
This works just like a signalling mirror, just not as strong.
5. Boiling water
You can actually boil water by folding the tin foil into a bowl. The video below shows you exactly how to do this.
There’s nothing like a tinfoil dinner under hot coals. In a survival situation, this might be your only option. Try your best to preserve that tin foil so you can re-use it multiple times.
You can also fold a flat piece over a “Y” shaped branch for a flat surface. Just make sure to fold the edges over the sides of the Y so the weight of you food isn’t too heavy for the foil to handle.
7. Reflect heat
Line the aluminum foil around your campfire or heater to redirect some of that heat back to you.
8. Collect water
You can either make a bowl shape or line the inside of something like your hat to collect rainwater.
9. Sharpen Scissors
Fold the tin foil so it is a few layers thick then cut into them with your scissors.
10. Clean grease from pots and utensils
Wrinkle up your aluminum foil a little then use it to scrape grease and gunk from your cookware. DO NOT use this on teflon type pots or it will cause unwanted damage.
11. Make gear water resistant
Wrap your gear in aluminum foil to protect it from moisture. This works great for fire starting material. Doing this will not make it water tight, but it will offer some protection.
