Squeaky reaches down and unsnaps one of the tubes from the bracket, holds it up in front of the bright lights of Chinatown. It had been transparent but was now smirched by heat and smoke. From a distance, it looks like a simple vial, but stepping up to look at it more closely Hiro can see at least half a dozen tiny individual compartments inside the thing, all connected to each other by capillary tubes. It has a red plastic cap on one end of it. The cap has a black rectangular window, and as Squeaky rotates it, Hiro can see the dark red glint of an inactive LED display inside, like looking at the display on a turned-off calculator. Underneath this is a small perforation. It isn't just a simple drilled hole. It is wide at the surface, rapidly narrowing to a nearly invisible pinpoint opening, like the bell of a trumpet.
