Just think of this.  We are going back to America in the 1700's  because we   
   can "Travel In Time".  We have just finished  a soft drink in a can and the   
   Inhabitations ask us, "What is that"?  And we're going to say, "It's in an   
   Aluminum can."  The    
   Inhabitants say,  "ALUMINUM".  What's ALUMINUM - it's surely a LIGHT can.  We   
   can't make Aluminum.  How do you Aliens do that"?  If we landed in New York   
   they would say, "You're God for inventing Aluminum".  And if we landed in   
   Connecticut they would say,   
    "You're Witches, for inventing Aluminum"!  Some aliens do not evaluate the   
   Prime Directive - we had secret exchange program with Serpo.
