Geography of Waterproof Matches.

The geography of waterproof matches is very interesting as there's a lot involved in the making of these matches. You have to have the right chemicals to stay smouldering even if it is submerged in water or covered in sand. This uses a magnesium compound to help keep the fire going even if it doesn't have oxygen, as the oxygen is created by the magnesium reacting with the heat. The match returns to being lit after it has come out from the water. many people use these in their survival kits, and they are very useful  if it is very windy as these matches will rarely go out. mostly these matches are safety matches but sometimes they are strike everywhere matches. these are usually made in china, with the materials coming from all over the world.
