If you ever want to f' with TSA in a completely legal way: carry lead crystal in your carry-on luggage. I've done it a number of times carrying Christmas gifts to/from family. My favorite was when my parents gifted me a set of lead crystal tumblers from Waterford. The cut on the crystal sorta makes them look like a pineapple grenade. Thing is, they're opaque on TSA scanners, so they make you pull them out (and they're really cautious at this point), then they pull the items out, and they're completely transparent. Their minds: blown. If you're lucky, you get one you can explain it to, if you're unlucky, you get a doofus that has to call for backup.
