Answer:
If you punched thousands of holes in the aluminum foil, you would see thousands of small images in the viewer.
Explanation:
If thousands of holes is punched/perforated in an aluminum foil, such that there were more holes than foil.
Thousands of small images would be formed, which can be seen in the viewer. Aluminum foil has a good reflective property which allows the thousands of holes punched to reflect equal number of images, although the images are smaller in size than the original image size.
