Pinhole camera:
  1. Take two boxes of cardboard such that one can slide into another with no gap in between them.
  2. Cut open one side of each box.
  3. On the opposite face of the larger box, make a small hole in the middle.
  4. In the smaller box, cut out from the middle a square with a side of about \(5\) to \(6\ cm\).
  5. Cover this open square in the box with tracing paper.
  6. Slide the smaller box inside the larger one with the hole, in such a way that the side with the tracing paper is inside.
  7. Your pinhole camera is ready for use.
