What are the ingredients for a fire? In order for a fire to be made, there has to be three essential things present: oxygen, heat, and fuel. A fire can be started with heat which is typically made through energy, whether it’s the flick of a match stick or rubbing two sticks together, each of these actions create heat. The heat then needs something to burn, which is where fuel comes in. Fuel can come in many forms such as dry brush, paper, gas, and oil amongst others. Lastly, a fire requires oxygen. You may have heard the phrase “let the fire breathe” before and it is very accurate since a fire needs to take in oxygen in order the kindle. If you were to close the lid of a candle, the flame would go out since it is no longer receiving any oxygen.
