If you ever want to have some fun flying, carry some lead crystal in your carry on luggage. A number of years back, I was visiting my parents for Christmas, and they gave me a set of lead crystal tumblers. Apparently due mostly to the lead and partly to the cut of the tumblers, they appeared as hand grenades on the luggage scanner. The look of absolute puzzlement on the TSA agents' faces were priceless. They could not reconcile what they saw on their scanners with what they held in their hand, even when I explained what it was. I've had similar experiences flying with lead crystal ornaments. Which, while always a gift, I never have wrapped while I'm flying, because I know, inevitably I'd need to open it, anyway.
