Now this liquid/gel does seem worth a TSA ban.

BoingBoing reader Skot shot this photo at a market in Costa Rica: a line of cleaning supplies called "Terror." Oh, what dark, foreboding poetry lurks in those long-lasting pink suds. Do we use it to cleanse the world of terror, or does the war on terror wash our Constitution away? One wonders what might become of the foolish adventure traveler who attempts to fly back to the US with this stuff in their suitcase. Link to larger size.
