According to him, he was on his way back to North Carolina from Greece when the TSA flagged his camera-case for manual inspection. The TSA agent reportedly produced the rocket-shaped blower, and then he and a colleague grimly pronounced the dangers of this object, should it be filled with gunpowder and then launched like a rocket through the cockpit.
Since then, Surapon assiduously sliced the decorative fins off his blowers, and has had no further trouble from the TSA.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
