This video demonstrates how to make a fire without any matches using the Swedish Firesteel magnesium fire starter. You need to have some good tinder, such as dryer lint or a cotton ball. To make it burn longer, you can use petroleum jelly. He puts some Vaseline on the cotton ball. He demonstrates the fire starter by putting one metal part on the dryer lint and scraping the other part on it. A spark lights the dryer lint and it burns quickly. He demonstrates again with the cotton ball soaked in Vaseline, which lights quickly and continues burning for a long time. The Swedish Firesteel fire starter is a handy tool to keep in your car or take camping.
