Re: Trolls : Building a Fire

In more recent years, a fourth component – the uninhibited chain reaction – has been added to explain fire. This chain reaction is the feedback of heat to the fuel to produce the gaseous fuel used in the flame. In other words, the chain reaction provides the heat necessary to maintain the fire.

We've moved on from the triangle but your analogy still works. Beware the uninhibited chain reaction
