What Makes Fire?

The people that had taken survival class or watch some kind of survival shows should get a basic idea of how to make fire. Even though Brian didn't actually go to any class that teaches how to make fire, Brian knows how to make fire from TV show, playing, and school. Brian knows that he can't make a fire without any materials. The first method Brian tries to use is rubbing the sticks together. He tries to use the friction of rubbing to produce fire. That method has failed.Why has Brian fail making fire the first time? Mabye he didn't rub the two sticks correctly, or mabye he's using the wrong kind of sticks.Well, it is very usual for him to fail, because he had never lived in the wilderness himself before, also, rubbing two sticks is really hard to make fire! Actually, it will be a miracle if he succeed the first time! Making fire require pratices. The second method Brian uses is hit the hatchet to produce sparks, and the sparks will make fire. This method requires a lot of strength. He needs to hit the hatchet enough times and strength in order to make enough fire. Also, wind affects the fire. After sparks are made, Brian blows them. He does that, because he knows that fire gets stronger by wind.. He tries and tries, and finally fire appears.
