How to make pinhole eclipse viewers

The American Astrological Society has also compiled the ultimate list that documents everywhere you can find safe eclipse glasses and viewers, online and in stores. You can seriously hurt your eyes and even go blind. But looking at anything as bright as the sun is NOT safe without proper protection.

This type of pinhole projector works on the same principle as a basic pinhole projector.

NASA posted a similar video explaining how to make a project with any old cardboard, but obviously it's more fun if pizza is involved. And it only requires a few extra items to construct. If so, there's still plenty of time for a homemade science project.
All you need to make a pinhole projector is a cereal box, a pin, a pair of scissors, some aluminum foil, and a roll of tape.

To make your projection a bit more defined, try putting the bottom piece of card stock in a shadowed area while you hold the other piece in the sunlight. The longer the box, the larger the projected image. The top of the cereal box should be sealed before cutting out square or rectangular holes on the left and right sides of the now sealed top. The next thing you do is stick a push pin into the tin foil so that the hole is big enough for the sun to peek through. The tiny holes will project the sun's image and ask the eclipse happens, all of the holes will become crescent-shaped. Place the box over your head with the pinhole towards the Sun.

A pinhole projection is a simple, low-cost, do-it-yourself way to see the image of the eclipse.
