   We poured distilled water through it and let it dry overnight (SoCal,    
   we're having a heat wave here).  One worked.  One partially worked, so    
   I'm going to be less gentle with that one and let it dry longer.  Yeah,    
   we have half a dozen waiting for revivification.   
      
   The differences are interesting.  On one the top just goes on easily.    
   On another you have to fit the bottom (closest to the spacebar) part in    
   first and remove some of the keytops and even then there's some magical    
   thing that we're missing.   
      
   And how many nutdriver sets have a thinwall 5.5mm or 7/32?  FEH!
