i love this - even if it turns out to be not fully correct in the end.
one thing i was wondering was if any evidence had been found about about the balloon floatation devices, and, along similar lines, if they modeled the idea that small barges atop the blocks might have worked instead of balloons.
fwiw : someone else posted this more detailed youtube video ..which has a good discussion of the rationale of the floats -- wood vs animal skin and papyrus.
