I suggest that everyone just find a few chunks of natural comb in the 
process of being built, such as the pieces bees build in packages or 
between widely spaced combs in a hive, or in a natural swarm, and sit 
down in a well-lit spot with whatever eye wear that is needed to see 
clearly, and ponder what is observed.

One chunk may not be enough as the cells under construction vary in 
completeness and orientation along the edge and around the curve of the 
comb edge.  Having several combs allows for verification of the 
observations made on any one cell by comparing to a comparable on 
another comb.

I think that after careful observation of many incomplete cells, the 
conclusions are quite obvious, although the exact mechanisms remain 
somewhat of a mystery.
