A light bulb is like a tiny sun inside your home. When you turn on the switch, it gives you light so you can see in the dark. But this little invention changed the world because it let people stay up later and work more hours. It also helped cities grow bigger and brighter.
Examples
- A child can read a book in bed with just one light bulb.
- A factory worker can stay up later to complete tasks thanks to the light bulb.
- A city is lit up at night by millions of tiny bulbs.
