<passage>:
"Feetch!" grated Ogden Piltdon, president of the Piltdon Opener Can-Opener!" roared Mr. Piltdon. "Look at our competitors. The International rips apart cans in three and three-tenths seconds. Universal does it in four." "But Mr. Piltdon—" can-opener lines. Departures, such as the thermal or motor-driven types, would be too expensive for mass production." Three new models and a group of cans were waiting for them on the bench. They began testing, Hanson operating the openers and Feetch but who has heard of Feetch? Well,"—Feetch blew his nose—"how do we "Hello," said Feetch as an aproned machinist entered carrying a he turned the handle, and stopped abruptly, staring down open-mouthed. A cylinder of close-packed beans rested on the bench under the opener. The can itself had disappeared. "Chief," said Hanson. "Chief." "Spinach, I think," said Feetch. "Where did the can go, do you suppose?" The spinach can disappeared. Likewise several corn cans, sweet potato cans and corned-beef hash cans, leaving their contents intact. It was rather disconcerting. "Dear, dear," said Feetch, regarding the piles of food on the bench. departures from the norm might achieve unconventional performance, but this—Dear, dear. Where do the cans go, I wonder?" "What's the difference? Don't you see what you've got here? It's the understand. What forces have we uncovered here? Where do the cans go? What makes them disappear? Are we dealing with a kinetic or a kinematic effect? What motions can we plot in the area of disappearance and what room and slapped Feetch heartily on the back, causing him to break a Feetch? The thing can be duplicated, can't it?" engineers. Find out where the cans go. Put out a scientific paper on the effect." "Feetch," bit out Piltdon, his face growing hard. "Stow this hooey. I don't give a damn where the cans go. May I remind you that under our nights at home investigating what had been named the Piltdon Effect. so many huge scientific organizations were working on it. But he could no more keep away from it than he could stop eating. He still didn't know where the cans went, but somehow he felt that he was close to the answer. When he finally found the answer, it was too late. The Borenchuck incident was only hours away. As soon as he could get hold of Piltdon, Feetch said trembling, "Sir, I think I know where those cans are going. I recommend—" "Are you still worrying about that?" Piltdon roared jovially. "Leave Feetch?" That night, at six-ten p.m., the Borenchuck family of Selby, South Dakota, sat down to their evening meal. Just as they started in on the soup, a rain of empty tin cans clattered down, splashed into the soup, raised a welt on the forehead of Borenchuck senior, settled down to a gentle, steady klunk! klunk! klunk! and inexorably began to pile up on the dining-room floor. They seemed to materialize from a plane just below the ceiling. The police called the fire department and the fire department stared helplessly and recommended the sanitation department. The incident made headlines in the local papers. The next day other local papers in widely scattered locations reported similar incidents. The following day, cans began falling on Chicago. St. Louis was next, and then over the entire nation the cans began to rain down. They fell outdoors and indoors, usually materializing at heights that were not dangerous. The deluge followed no pattern. Sometimes it would slacken, sometimes it would stop, sometimes begin heavily again. It fell in homes, on the streets, in theatres, trains, ships, universities and dog-food factories. No place was immune. People took to wearing hats indoors and out, and the sale of helmets boomed. All activity was seriously curtailed. A state of national emergency was declared. Government investigators went to work and soon confirmed what was generally suspected: these were the same cans that had been opened by the Piltdon Super-Opener. Statisticians and mathematicians calculated the mean rate of can precipitation and estimated that if all the cans opened by Piltdon openers were to come back, the deluge should be over in fifteen point twenty-nine days. bodily injury. Lawsuits were filed against him. He barricaded himself in the plant, surrounded by bodyguards. Livid with fury and apprehension, he screamed at Feetch, "This is your doing, you vandal! I'm a ruined man!" A falling can caught him neatly on the tip of his nose. "But sir," trembled Feetch, dodging three spaghetti cans, "I tried to warn you." "You're through, Feetch!" raved Piltdon. "Fired! Get out! But before the Super-Opener. Now, get out!" "Yes, sir," said Feetch paling. "Then you don't want to hear about my discovery of a way to prevent the cans from coming back?" Klunk! A barrage of cans hit the floor, and both men took refuge under Piltdon's huge desk. "No!" yelled Piltdon at Feetch's face which was inches away. "No, I——What did you say?" "A small design improvement sir, and the cans would disappear forever." Klunk! "Forever, Feetch?" "Feetch!" howled Piltdon. "I order you to remain!" Feetch almost submitted from force of habit. He hesitated for a moment, then turned abruptly. "Good-day," said Feetch firmly, sprinting through the falling cans to the door. Money, Feetch decided after a while, was a good thing to have. His supply was running pretty low. He was not having any luck finding another job. Although the cans had stopped falling on the fifteenth day, as predicted by the statisticians, industry would not soon forget the inconvenience and losses caused by the deluge. It was not anxious Feetch. I know you can't find work anywhere else." "Thanks to you. Mr. Piltdon, I wouldn't work for you if—" A barrage of rocks crashed against the heavy steel screening of the window. "What's going on!" yelled Piltdon. "Oh, I see. People throwing rocks at your house again? Oh, I know all about that, Feetch. I know that you're probably the most unpopular man alive to-day. I know about the rocks, the tomatoes, the rotten eggs, the sneaking out at night, Feetch blinked. This had not occurred to him. Feetch sat, thinking it over. Was it right to let all these people lose Feetch hung up. A glow of anger that had been building up in his chest Feetch walked into the kitchen and carefully poured himself a drink of hand. "Here is everything I know about what I call the Feetch Effect, Piltdon threw the paper to the floor and screamed: "Gentlemen, will you be a party to this?" "Well," murmured the Government man, "I never did think Feetch got a in inverse proportion to the cube root of the tolerance between the involute teeth caused an instantaneous disruption of what I call the Alpha multi-dimensional screen. The can, being metallic, dropped through, leaving its non-metallic contents behind. The disruption was indicated, Alpha space seems to be thickly inhabited. These inhabitants, the nature of whom I have not yet ascertained, obviously resented the intrusion of the cans, developed a method of disrupting the screen from their side, and hurled the cans back at us. "However, I have established the existence of other spaces up to Mu Feetch looked up from his desk in the newly constructed Feetch "But Mr. Feetch—" "Get out," said Feetch.
