The Greatest Invention
There have been many great inventions that have changed our lives. But the light bulb is the greatest invention in my mind.
It was invented in 1854.It was invented by Thomas Edison. And it is used for seeing in the dark. It's made of glass and looks like a ball.It has brought bright to the world since it was invented. With light bulb, people can do more things than before.
I think it’s a great /useful/invention. I believe that it is a small invention that changed the world. What's more,Thomas Edison was a great inventor. I also want to be an inventor like him.
