Quick Answer
Magnifying lenses can work on wet tinder, but they may not be as effective as they would be on dry tinder. This is because the water on the tinder can make it difficult for the heated spot to ignite. A good approach is to focus the magnifying glass on a small area and slowly move it around to help evaporate the water.
Choosing the Right Tinder
When using a magnifying lens on wet tinder, it’s essential to choose the right type of tinder. Look for material that is highly absorbent and will dry quickly, such as dry grass, small twigs, or shredded bark. Avoid using wet leaves or pine needles, as they can be too dense and difficult to ignite. Opt for small pieces of tinder, about 1-2 inches in size, to increase the surface area for the magnifying lens.
Focusing the Magnifying Lens
To use a magnifying lens effectively on wet tinder, follow these steps: (1) adjust the focus to create a sharp, hot spot; (2) hold the magnifying lens at an angle to concentrate the sun’s rays onto a small area; (3) slowly move the lens up and down to help evaporate the water; (4) maintain a consistent distance between the lens and the tinder, about 1-2 inches. The goal is to create a small, hot ember that will eventually ignite the tinder.
