Let's make a camera.
Here is a drawing of camera on the cardboard.
Let's cut along the line and fold it
Then put this oil-paper on the box. It will work like a film on the real camera.
Then here is a lens. I got this from magnifying glass
Now turn on the TV. and watch the oil-paper through the lens.
What can you see?
Look. TV screen is here ~!! upside down!!!
