Although I mostly post High Tech articles and know-how on the blog. I also like anything interesting related to the outdoors or how-to stuff from the past. Here is an article I came across, that shows you how to take a piece of ice and shape it into a sphere to make a solar lens, which by the way is capable of starting a fire. A similar technique can be acheived from water that is housed in a plastic bag or saranwrap. Who knew ;) So the next time you are lost in the woods, or forgot your matches at the family picnic and need to start the grill, remember these techniques.
