Wallet Sized Magnifying Glass
Wallet Sized Magnifying Glass - 5 Pack The Fresnel lens functions like a regular magnifying glass, except it is flat instead of lens-shaped. Starting a fire with a Fresnel Lens card magnifier is just like using a regular magnifying glass. Collect a wad of dry, fluffy tinder, such as the dry inner bark of a dead cottonwood, and focus the light of the lens on the tinder to start it smoldering. When you have a glowing coal, then you can blow on it to make it grow until it ultimately bursts into flame. Do keep in mind that card magnifiers only work when the sun is shining..
