| | |   Anodized titanium earrings. These are silly little Space Needle tourist earrings I got on a trip to Seattle with my son.  They are either laser or water-jet cut, I'm not sure how to tell the difference for sure, but if I had to guess I would say water-jet because of the slightly larger diameter of the cut at the start and finish of each line.  A laser should cut perfectly.  But that's just a guess.
 The color comes from anodizing the titanium, as I have written about in my Popular Science Column.
