  • This might be a situation you never thought could happen, but here you are cast away on

  • a deserted island with nothing but the clothes on your back. In this project we'll be making

  • a survival fire by rubbing sticks together, because if you can do that, you'll have a

  • much better chance of being found alive.

  • Looking around the island, the first thing you notice are plenty of coconut trees and

  • at the base are some old coconut husks. Those might come in handy. There's also plenty of

  • wood lying around, so you just need to find a dry piece of a soft wood, like this branch

  • from a hibiscus tree. Hibiscus is a very lightweight wood and when it's this dry, it's a great

  • choice. Your old coconut husk will make a great tinder bundle because it's packed with

  • very fine fibers that should burn easily. Ok, to prepare these sticks for a friction

  • fire, it's important that both sticks come from the same branch. A sharp rock can be

  • used to fashion some of the wood into a long narrow stick, cutting the tip of the stick

  • so that it's slanted at a 45º angle on both sides. When it's ready, it should look like

  • something like this. Now use your sharp rock to carve a flat spot into the other piece

  • of wood, knocking it down until you've got a surface at least 8 inches long, then make

  • a groove down the center to act as a track for guiding the other stick. Ok, the last

  • step is to wedge anything you can find under the base to help stabilize it, then go sit

  • down on the back. It's time for the action. Taking the shorter stick in your one hand

  • like this, place your other hand overtop so that the stick nestles in securely at the

  • base of your thumbs. Ok, when you've got the tip set firmly in the grooved track, try pushing

  • it back and forth, keeping it at a 45º angle to the base. Not much pressure is needed yet,

  • so don't worry about putting too much effort into it. When the heat of the friction builds

  • to where the wood is ready, you'll notice a change in how it feels and might even see

  • a little smoke. At this point, push a little faster, and use your strong hand to pull down,

  • adding pressure to the tip. You should see a lot more smoke now, and bits of charred

  • wood dust starting to pile up at the top. Put your back into it and increase the pressure,

  • making sure the tip is stopping just short of the pile. It looks like you've got a little

  • ember burning now, but let's continue just a little longer to be sure. Hopefully when

  • you stop it will keep smoking. Ok perfect, you've got a nice little coal. Now, go turn

  • it into a flame. This is a good time to get your coconut husk ready by pulling apart the

  • fibers. The fluffier they are, the better. Transferring the coal is a delicate process,

  • so try pressing the husk right up to the coal, then turn the ember base over and tap the

  • bottom with a stick to make sure all the embers transfer out. Nice, your coal has been captured,

  • so loosely cover it over with more fibers so that it's protected from the wind, and

  • continues to smolder. Patience is a virtue here. You don't want to pinch it too tight

  • or you'll smother it out. Too loosely and the fibers won't burn. The heat needs to build

  • slowly, so try to balance the amount of air the coal is getting, with the quantity of

  • tinder it's exposed to. The amount of smoke being generated is a good indication of how

  • well you're doing, and sometimes blowing gently can help speed the process. When the smoke

  • is thick and you can start to feel the heat radiating, it's time to get a little more

  • aggressive. Waive the bundle around to get some more airflow, and blow right into the

  • center of the coals. Just a little more air now, and success! There's your flame! The

  • hardest part is over, but don't pat yourself on the back just yet because by the time you

  • add some wood shavings, your flame may be going out. Not to worry though, because as

  • long as the smoke is thick, there's still a good amount of heat, and the same techniques

  • can be used for blowing the coals back into a flame. Well there you have it. Now you can

  • start a fire by rubbing sticks together, now best of luck getting rescued. If you liked

  • this project, perhaps you'll like some of my others. Check them out at www.thekingofrandom.com
