    Most of the airports in the US have some sort or chemical detector too. I always get my hands swapped going through PDX because I brought so scary looking circuit boards with my carryon 5 years ago.

        It’s been a few years, but they are white round pads, probably 3 inches wide. I’m not sure what’s on the pad, probably a solvent of some kind.

        The pads go in a machine about the size of an larger microwave oven which I believe uses NMR to scan for nitrates and other kinds of explosive residue.

        It was a pair of highschool level sumo robots, lots of wires and motors and gears.

          In case you haven’t realised, the correct word is swab/swabbed. You are being made fun of for swapping the correct word for a different word.
