💡 Fun Facts
- Inside a bulb is a tiny, thin wire called a 'filament'. When electricity flows through it, it gets so hot that it glows, giving us light.
- Early light bulbs didn't last very long. Modern LED bulbs can last for 25,000 hours or more!
- Thomas Edison is famous for inventing the light bulb, but a British man named Joseph Swan made a very similar one at the same time!
