One of the greatest outdoor experiences is sitting around a warm, cozy campfire to tell stories, roast hot dogs and marshmallows, or simply poke at the flames with a stick. However, you want to enjoy the outdoors without harming the outdoors. The following are ways to safely build a fire outside:

Murphy’s law can strike at anytime and anywhere–especially in the outdoors. Your matches may get wet or lost or your lighter may run out of lighter fluid–and there are no stores nearby to purchase more matches or lighters. So how can you start a fire without matches? All you need is a shiny piece of metal and some steal wool. Find a piece of metal; an aluminum soda can works the best, but a can lid would also work fine. Use the steal wool to polish the metal until you can see your reflection in it. Without a good glare, the can will not reflect enough light. Then hold a piece of tinder near the metal until the reflection of the sun causes the tinder to catch on fire.

Another unique way to start a fire without matches is by using a magnifying glass. Hold the lens at an angle until you focus the sun’s light on the spot where you are going to start your fire. Hold it steady until a fire starts. If you don’t have a magnifier, any clear magnifying lens will do. You can even use your glasses–the more farsighted you are the better.

It’s always a good idea to bring a cellphone on a camping trip in case of an emergency or to start a fire. That’s right. By using the battery of a cellphone, or a regular battery, you can create a fire. Take a piece of steal wool and rub it on the battery’s connectors until you get a spark.

With these three unique methods of building a fire you’ll be roasting marshmallows in no time.
