Here is a useful link about the engineering properties of sand castles. It's mostly about the moisture content.

Thanks for this — gives us a break from the excitement (or boredom?) of the Olympics.
We hadn'te really focused on this before, but now we know that, without water, sand is useless as a building material.
The article and the comments present a fascinating discussion of exactly (dull men like to be exact) how much water to add to the sand in order to make sand castles.
Great topic for DMC meetings.
