Mary,

I think that it's difficult and expensive to obtain because it is 
actually fairly complicated to produce, rather than because of a "car 
that runs on water" type of conspiracy by The Man. However, the basic 
components, air and sand, are dead common. Imagine making entire rockets 
or buildings out of the stuff - strong, lightweight, and an excellent 
insulator.

These pages will give you an idea of how it is made...
