This is my camera obscura as shown. I created it from a cereal box, cutting out a large gap in the center to make the aperture of the obscura. I used the cereal bag as the screen and taped it to the front face of the cereal box. Lastly, I used a push pin to puncture a hole in the opposite face of the screen or back of the cereal box to allow the light to pass through and create the inverted image effect which appears on the screen.
