Brazier effect

Imagine you are sitting around a campfire with your friends roasting marshmallows. You notice that the fire in the center is burning brightly, but the flames around the edges are much smaller. This is the brazier effect!

When you start a fire, the flames are in the middle because this is where the heat and fuel are concentrated. As the fire burns, the hot air rises and creates a current, like a little wind. This current draws air in from the outside to feed the fire, but it also cools down the air around the edges.

Because cooler air is denser, it sinks to the ground, and some of it gets sucked into the fire near the edges. However, since it's not as hot as the air in the center, it doesn't burn as well, and this makes the flames smaller.

This cycle repeats over and over, with the hot air rising, cool air sinking, and the fire burning brightest in the center. That's why you want to be near the middle of a campfire to stay warm and roast your marshmallows to perfection!
