Is it really a liquid?  Glaciers flow over long periods of time.  Steel flows 
but we don't think of it as a liquid.  Isn't it the rate at which it flows 
that determines if it is a liquid?  Or is it the motion of molecules in the 
chemical or compound that determines whether it is a solid or liquid?
