January 11, 2013: Time's Natural Keeper

Hold your tongues just one moment, as I've a question for the lot of you.  What mostly comprises dry, arid deserts, and warm, humid beaches?  What do you usually find in an hourglass?

  
The fate of all rocks that succumb to erosion is to slowly, but surely, be turned into the granulated substance known as sand.  There's more grains of it in a single desert than there are people on the entire planet, and it can all provide for very grainy fun.  Handle it correctly, and any number of things may be created from it, including castles and perhaps even large sand statues!  It's also perfect for living beings who prefer dryer habitats, too.
