The pencil lead and a glass jar actually turn it into a light bulb!💡

an you believe it? An ordinary mechanical pencil lead, a candle, and a glass jar are all it takes to make a real light bulb!💡

In this physics experiment, I burned a candle inside the jar to consume oxygen and create a low-pressure environment. Then, I sealed the pencil lead inside as a filament. The moment I connected the power—magic happened! The pencil lead emitted a dazzling bright light, far brighter than imagined!🤯
