Fire by ice optical method

Now that Summer has arrived, the sun is at it’s best for optical fire methods. You can use concave reflectors that you point at the sun and find the focus point where you hold the tinder. Some items that I’ve used include flashlights, soda cans, broken headlights, jewelry, doorknobs, compact mirrors, etc. Also, you can use convex lenses. Some items that I’ve used include marbles, paper weights, magnifying lens, fresnel lens, clear light bulbs, vases, plastic bags, etc. Visit my Contact page and drop me a line with other items that you have used!
