Fire

I was observing fire and how it looks/works. Based on it's size and temperature it works and appears quite different. A small match of fire flickers and is quite weak, especially when it is moving. The air nearly puts out the flame if a match moves too quickly.
A bonfire is quite different. Once it gets going, a three foot fire crackles and produces quite a bit of heat. It flickers more toward the tips of the flame at a fast pace. When a log is taken from the bonfire, still ablaze, it can continue to burn but becomes weaker the longer it's away from the fire.
Weak fires are more effected by the wind, and also stay closer to their fuel source; For instance, when a log is taken from a bonfire and the fire is strong it will burn about three inches tall, but as it becomes weaker and closer to going out, the fire clings to the wood for dear life, and reduces to less than an inch in height.
