Inspirations for new survival techniques can come from a number of sources. I watched a new show on The National Geographic Channel last night called Hacking the System that had several good ideas. I am sharing two short videos from the show that will be added to my list of DIY survival projects and ideas. One is on a method for starting fire with a battery and steel wool and the other is for an improvised gas mask. I’m not sure how the gas mask will work but it has to be better than nothing.
