The mistake being made by the man in this video is not compacting his tinder close enough, and doing nothing about it once he saw that his blowing air on the embers was NOT lighting the tinder. He should have taken his hand and quickly pushed the tinder tighter around the embers, and then blown again. He did the blowing, several times, but with the same result.
He could have chosen better tinder to light. Hay and grass are okay, but often contain water because the fibers are very thick. In the snow and cold this is especially true. Thinner fibers, such as milk weed down, or finely shredded cotton or linen fibers, hemp rope that is unraveled, or even Jute string that is unraveled make a much faster igniting tinder to use in these conditions.
When I use straw, I create a good size bundle, and then fold it in half to make a pocket for my charcloth. Once I blow an ember into a good size ember in the charcloth, I simply pin wheel the bundle with my arm making a circular movement over my head and down to my side, like a ferris wheel, to light the bundle of straw. I find that with straw, this gets the job done fast, as the amount of air that is fanned into the ember, and then to the bundle of straw is much faster with this movment, than anything I can do with my lungs.
It was nice to see a guy experienced enough starting fires to pick the bundle up and put it above his head to blow into it from the bottom, rather than blowing down into it, as many people do, only to get smoke in their face! I have seen far too many singed eyebrows over the past 40 years, and its nice to know that someone has demonstrated the correct position to use when blowing an ember into fire. :grin: :thumbsup:
