How to make the pinhole projector

Take your box -- I used a cereal box -- and trace its bottom on your sheet of newspaper.
Cut out the rectangle you just traced and record it to the lesser of the inside of your box. This will be your projection screen.
Close the top of the box and cutting 2 holes along the correct and left edges of the summit panel.
Cutting a piece of aluminum foil to cover 1 of the holes and tape it in place.
Poke a pigsty in the eye of the piece of foil.

How to use your projector

Take your pinhole projector outside and face away from the sun then that its light shines into the pinhole. Look through the hole you did not encompass and you lot will see the sun projected on the white piece of paper inside the box. The longer the box, the larger the image will be.

Like shooting fish in a barrel, box-less alternative

Easier and ameliorate for group viewing is skipping the box and punching a pinhole into a sheet of paper and then simply projecting the sunlight through that pinhole onto another sheet of white paper on the ground. The image of the sun won't be as brilliant every bit it is projected inside a dark box, only information technology should work merely fine if you have articulate skies and bright sunshine.
