@teachyouman on Instagram: "This experiment proves that fire has to occupy space to burn an object — combustion isn’t just heat, it’s a physical process. Flames are made of hot gases produced during burning, and these gases take up space. If there’s no room for the flame to exist — or no fresh oxygen to replace it — the fire can’t sustain itself and goes out. Safety note: Never perform fire experiments indoors or without supervision. Keep water or a fire extinguisher nearby at all times. This de

Even the brightest flame can dim under the weight of stress, trauma, and life’s challenges.
