As an old school architect with 20-years specializing in forensic investigations, IMHO, the
Box of Truth is interesting; but, not an indicator of the number of walls a given load will penetrate. It should be used only for relative comparisons like wet newsprint or plastic water jugs.
I suspect gypsum wallboard was selected because it's easy to work with and inexpensive. From the pics, it appears the
Box of Truth uses 5/8-inch thick fire-code gyp-board, where typical partitions use standard 1/2-inch. Not only is the
Box of Truth gyp-board thicker, it's stronger (fire-code is reinforced). Also, the gyp-board in the
Box of Truth is closely spaced allowing a domino effect from panel to panel. Other factors, including perimeter support, various wall finishes and cavity insulation contribute to differences between the
Box of Truth and real world walls and partitions.
