BY RICK RAPHAEL That the gentleman in question was a nut was beyond question. He was an institutionalized psychotic. He was nutty enough to think he could make an atom bomb out of modeling clay! Illustrated by Freas She stopped behind a frowning, intense patient, rapidly shaping blobs of clay into odd-sized strips and forms. As he finished each piece, he carefully placed it into a hollow shell hemisphere of clay. "And what are we making today, Mr. Funston?" Miss Abercrombie asked. The flying fingers continued to whip out the bits of shaped clay as the patient ignored the question. He hunched closer to his table as if to but firmly. "You've been coming along famously and you must remember to answer when someone talks to you. Now what are you making? It looks very complicated." She stared professionally at the maze of clay parts. Thaddeus Funston continued to mold the clay bits and put them in place. Without looking up from his bench he muttered a reply. "Atom bomb." A puzzled look crossed the therapist's face. "Pardon me, Mr. Funston. I thought you said an 'atom bomb.'" smears. He sighed happily and laid down his palette. At the clay table, Funston feverishly fabricated the last odd-shaped bit of clay and slapped it into place. With a furtive glance around him, he clapped the other half of the clay sphere over the filled hemisphere and then stood up. The patients lined up at the door, waiting for the walk made short, precise notes on the day's work accomplished by each patient. At the clay table, she carefully lifted the top half of the clay ball and stared thoughtfully at the jumbled maze of clay strips laced through the lower hemisphere. She placed the lid back in place and jotted As she drove out of the hospital grounds, Thaddeus Funston stood at the At 3:01 a.m., Thaddeus Funston stirred in his sleep and awakened. He sat An instant later, the shattering roar and blast of the explosion struck Thaddeus Funston took his hands from his face and lay back in his bed explosion. None had. The hills had absorbed most of the shock and apart from a The roar and flash of the explosion had lighted and rocked the Atomic Energy Commission experts, military intelligence men, four FBI In Ward 4-C, Thaddeus Funston slept peacefully and happily. experts gathered in the tent erected on the hill overlooking the crater. "How can an atom bomb go off in a nut house?" "It apparently was a very small bomb, colonel," one of the haggard AEC men offered timidly. "Not over three kilotons." "I don't care if it was the size of a peanut," Thurgood screamed. "How did it get here?" A military intelligence agent spoke up. "If we knew, sir, we wouldn't be standing around here. We don't know, but the fact remains that it WAS an atomic explosion." Thurgood turned wearily to the small, white-haired man at his side. through the use of their hands, some of the frustrations and problems that led them to this hospital. They worked with oil and water paints and clay. If you can make an atomic bomb from vermillion pigments, then Madame Curie was a misguided scrubwoman." "All I know is that you say this was a crafts building. O.K. So it was," Thurgood sighed. "I also know that an atomic explosion at 3:02 this morning blew it to hell and gone. "He did make an atom bomb," she cried. Colonel Thurgood, who had snapped from his chair at her words, leaped every beat. "It's ridiculous," Thurgood roared. "We'll all be the laughingstocks of the world if this ever gets out. An atomic bomb made out of clay. You are all nuts. You're in the right place, but count me out." At his left, Miss Abercrombie cringed deeper into her chair at the "Miss Abercrombie," one of the physicists spoke up gently, "you say that The therapist nodded unhappily. "And you say that, to the best of your knowledge," the physicist continued, "there was nothing inside the ball but other pieces of clay." "I'm positive that's all there was in it," Miss Abercrombie cried. There was a renewed buzz of conversation at the table and the senior AEC Thurgood leaped to his feet, his face purpling. "Are you crazy?" he screamed. "You want to get us all thrown into this ever got wind of the fact, that for one, tiny fraction of a second, anyone of us here entertained the notion that a paranoidal idiot with the IQ of an ape could make an atomic bomb out of kid's modeling clay? "They'd crucify us, that's what they'd do!" At 8:30 that night, Thaddeus Funston, swathed in an Army officer's secrecy under the National Atomic Secrets Act, bundled Thaddeus aboard The plane landed the next morning at the AEC's atomic testing grounds in There was nothing on the table but a bowl of water and a great lump of modeling clay. While the psychiatrists were taking the strait jacket off Thaddeus in the staff car outside, Colonel Thurgood spoke to the weary Miss Abercrombie. "Now you're positive this is just about the same amount and the same kind of clay he used before?" "I brought it along from the same batch we had in the store room at the hospital," she replied, "and it's the same amount." Thaddeus Funston between them. The colonel nudged Miss Abercrombie. one you made for me yesterday." A flicker of interest lightened Thaddeus' face. He looked around the shack and then spotted the clay on the table. Without hesitation, he walked to the table and sat down. His fingers began working the damp clay, making first the hollow, half-round shell while the nation's top atomic scientists watched in fascination. His busy fingers flew through the clay, shaping odd, flat bits and clay parts that were dropped almost aimlessly into the open hemisphere in front of him. Miss Abercrombie stood at his shoulder as Thaddeus hunched over the table just as he had done the previous day. From time to time she glanced at her watch. The maze of clay strips grew and as Funston finished shaping the other half hemisphere of clay, she broke the tense silence. The two psychiatrists went to Thaddeus' side as he put the upper lid of from the shack. There was a moment of hushed silence and then pandemonium burst. The experts converged on the clay ball, instruments blossoming from nowhere and cameras clicking. For two hours they studied and gently probed the mass of child's clay and photographed it from every angle. Then they left for the concrete observatory bunker, several miles down range where Thaddeus and the psychiatrists waited inside a ring of "I told you this whole thing was asinine," Thurgood snarled as the Thaddeus Funston stared out over the heads of the MPs through the open Six hours and a jet plane trip later, Thaddeus, once again in his strait asylum inmate in a strait jacket and you have the colossal gall to sit there and tell me that this poor soul has made not one, but two atomic devices out of modeling clay and then has detonated them." The general paused. "Why don't you just tell me, colonel, that he can also make spaceships In the next room, Thaddeus Funston stared out over the sweeping panorama
