by his under-scanners. He stopped. His head began to swivel. The crowd watched in eager silence. This was Robie's best trick. Robie's head stopped swiveling. His scanners had found the traffic light. It was green. Robie edged forward. But then the light turned red. Robie stopped again, still on the curb. The crowd softly ahhed its delight. It was wonderful to be alive and watching Robie on such an exciting day. Alive and amused in the fresh, weather-controlled air between the lines of bright skyscrapers with their winking windows and under a sky so blue you could almost call it dark. (But way, way up, where the crowd could not see, the sky was darker still. Purple-dark, with stars showing. And in that purple-dark, a silver-green something, the color of a bud, plunged down at better than three miles a second. The silver-green was a newly developed paint that foiled radar.) Robie was saying, "While we wait for the light, there's time for you youngsters to enjoy a nice refreshing Poppy Pop. Or for you adults—only those over five feet tall are eligible to buy—to enjoy an exciting Poppy Pop fizz. Just give me a quarter or—in the case of adults, one dollar and a quarter; I'm licensed to dispense intoxicating liquors—and within five seconds...." But that was not cutting it quite fine enough. Just three seconds later, the silver-green bud bloomed above Manhattan into a globular orange flower. The skyscrapers grew brighter and brighter still, the brightness of the inside of the Sun. The windows winked blossoming white fire-flowers. The crowd around Robie bloomed, too. Their clothes puffed into petals of flame. Their heads of hair were torches. The orange flower grew, stem and blossom. The blast came. The winking windows shattered tier by tier, became black holes. The walls bent, rocked, cracked. A stony dandruff flaked from their cornices. The flaming flowers on the sidewalk were all leveled at once. Robie was shoved ten feet. His metal hoopskirt dimpled, regained its shape. The blast ended. The orange flower, grown vast, vanished overhead on its huge, magic beanstalk. It grew dark and very still. The cornice-dandruff pattered down. A few small fragments rebounded from the metal hoopskirt. Robie made some small, uncertain movements, as if feeling for broken bones. He was hunting for the traffic light, but it no longer shone either red or green.
