Wet matches can be a camper's or a smoker's worst nightmare. Conventional wisdom dictates that when the match is wet, no amount of friction will ignite the tip of the match. If the water gets too absorbed into the match, it may harm the fuel within the red tip that keeps the match going. However, if you desperately need to light a match that is wet, there are a few things you can do that may help you re-ignite the match.
Immediately get out of any area where moisture and water may be hitting you. If you are out in the rain or it's densely moist in the air, try to find a dryer spot to begin drying the match.
Find a long block of dry wood. The end of your match book is not long enough to support a clean sweep needed to evaporate the moisture.
Quickly run the match across the dry wood as fast as you can. Utilize the whole length of the wood piece so there is a larger amount of friction hitting the match tip than you would see on the back of a matchbook. Repeat this a few times until the match lights up or the match breaks.
Wrap the match in some aluminum foil.
Place the foil-covered match in some sort of warming device, like an electric oven. Theoretically, you can place a match in an electric oven and have the match ignite from the raised temperature. If you simply want to have moisture disintegrate from the match, just raise the temperature slightly below 212 degrees Fahrenheit so the water or moisture evaporates from the foiled-covered match.
Wait for the match to cool down. Once it has cooled down, repeat the experiment again against the long dry wood.
