17.Starting a fire with ice wasn't a joke.You can make it if you do it right and have the patience.How to start a fire with ice is important if you are caught in the wilderness (野外) during the winter months when there is snow and ice covering the ground and trees.
The first thing you need do is to find a place on the side of a hill or near a tree that is dry and protected from the wind.Although a tree is easier to find,you run the risk of catching the tree on fire.Next,you will need to collect some small dry pieces of bark(树皮) or bushes for kindling (点火物) and place them together on your dry protected area,and then find a good supply of larger dry tree branches for your fuel(燃料) once you get the fire started.
Now you have to find an ice sickle (镰刀) only about a foot long,and while the sun is still up,hold the ice sickle in the air where it catches the sun on the larger end and concentrate the sun light coming out of the smaller end toward your kindling.If you have a hard time getting your kindling to ignitebecause it's too large,you can always gather and use any dry grass or paper you can find to help get your fire going easier.While you are trying to light your kindling,remember to keep your fire material dry without any water.
You don't worry about it.If you melt(融化) your ice sickle trying to start the fire,you can always just get another one.With practice and patience anyone can get the skills of fire from ice.
