General Physics Science Fair Project

Make a Pinhole Viewer

Make a Pinhole Viewer | Science Fair Projects | STEM Projects
Have you ever wanted to see the world in a different way? With this project, you can make a pinhole viewer that lets you see the images carried by light shining through a pinhole.


The hypothesis is that a pinhole viewer will allow you to see the images carried by light shining through a pinhole.

Method & Materials

You will cut a big flap in the front of the box, cut a piece of waxed paper and tape it inside the box, use a pushpin or thumbtack to make a hole in the bottom of the box, and cut off the flaps from the top of the box.
You will need an empty cereal box or laundry detergent box, waxed paper, black tape or silver duct tape, an X-acto knife, a single-edged razor blade, or scissors, and a pushpin or thumbtack.


When you look into the opening in the top of the box, you will see an upside-down and backward image of the scene in front of you on the waxed paper screen inside the box. If you make the hole bigger, the image will get brighter, but also more blurry.

Why do this project?

This science project is interesting because it allows you to see the world in a different way.

Also Consider

Experiment variations to consider include making more than one hole in the bottom of the box to get more than one image, and using the black tape to make a flexible flap along the edges where you removed the boxtop and the flaps to help block out light.
