A Solar Spark Lighter or Sunlighter is a pocket-sized stainless steel parabolic mirror , shaped to concentrate sunlight on a small prong holding fuel material at the focal point. A revival of an old gadget marketed as a cigarette lighter by RadioShack in the 1980s, it is a useful camping device and its operation is not affected by having been soaked by rain or falling in rivers or the sea. To be sure it is a sunlight and a small piece of flammable material. Once a glowing spark has been achieved, careful blowing will produce a blaze. Its simplicity, small size and light weight make it a useful item in a survival kit . [1]
