What is Fire Made Out of?

What fire is made out of is an ignition source such as a fuel, heat, and oxygen. Heat can be generated from rubbing to sticks together vigorously and creating spark, or by using a magnifying glass with the sun. Fuel could be sticks and twigs you have picked up and put in a pile. And of course, oxygen would be the air. Combining these elements would create fire. You can find more information here:
