Much of the investigation turns on the chance encounter of a seamstress seeing the reconstricted tent and choosing perhaps on of the many damaged pieces and says, " cut fron the inside". I propose an experiment where numerous squared pieces of canvas are put to the test perhaps as follows. Common to all they mounted upright and in proximity to each other
1. Square 1 is uncut and mounted ( this is the standard of comparison, or control piece)
2. Square 2 sliced with a blade front to back ( as if the tent were cut from outside)
3. Square 3 sliced,with a glade from back to front ( as if cut from,within the tent)
4. Square 4 is punched through and hand torn to make a ragged tear. ( as if cheap fabric wore out)
5. Square 5 is attached to a separate piece of canvas effectively becoming a flap which may beat the square,
What would it demonstrate? I predict that if these samples were subjected to the test conditions, then all would be frayed to the extent that a knife cut would undetectable.
Documant all photographically and then turn on the fan blowing all uniformly in one direction. In time, check for changes.
