That's rather odd, I did not recall posting a photo of the bullet boxes, so I am not sure what you are looking at to get the impression "newspaper hung over something" and having air space in between?
Possibly you were looking at something else and become confused? My wet print medium is not hung, it is stacked in boxes 65 inches long inside, and the width of a newspaper. I also every 10-12 inches insert 1.5-2 inches of catalog/magazine mixed in, this is amazingly tough on bullets. It is soaked over several days to make sure it is soaked through and through, and lightly compressed. When testing properly designed solids I have to place test medium in a second box to catch anything that goes past 65 inches.
