A pinhole projector is a device that projects an image through a small hole in an object, onto a surface, allowing you to safely observe light, like the Sun. It is a convenient method for safe viewing of the partially eclipsed Sun. With the Sun behind you, you can pass sunlight through a small opening, such as a hole punched in an index card, and project a solar image onto a nearby surface, such as another card, a wall, or the ground. You can also use two pieces of cardboard to make a simple pinhole projector. To make a quick version of the pinhole projector, take a sheet of paper and make a tiny hole in the middle of it using a pin or a thumbtack. Make sure that the hole is round and smooth. With your back towards the Sun, hold one piece of paper above your shoulder allowing the Sun to shine on the paper. The second sheet of paper will act as a screen. Hold it at a distance, and you will see an inverted image of the Sun projected on the paper screen through the pinhole.
