Retief stepped to the machine, dropped the coin. Retief "If you want to change your mind," the man said, "you can back out now. All it'll cost you is the chip you dropped." Retief reached through the hole, took the grip. It was leather padded hand-filling. He squeezed it. There was a click and bright lights sprang up. The crowd ah!-ed. The globe began to twirl lazily. The four-inch hole at its top was plainly visible. "If ever the hole gets in position it will empty very quickly," Magnan said, hopefully. Suddenly, a brilliant white light flooded the glass cage. A sound went up from the spectators. "Quick, drop a chip," someone called. "You've only got ten seconds...." "Let go!" Magnan yelped. Retief sat silent, holding the grip, frowning up at the weight. The globe twirled faster now. Then the bright white light winked off. "A bluff!" Magnan gasped. "That's risky, stranger," the gray-templed man said. The globe was turning rapidly now, oscillating from side to side. The hole seemed to travel in a wavering loop, dipping lower, swinging up high, then down again. "It has to move to the bottom soon," Magnan said. "Slow it down." "The slower it goes, the longer it takes to get to the bottom," someone said. There was a crackle and Retief stiffened. Magnan heard a sharp intake of breath. The globe slowed, and Retief shook his head, blinking. The broad-shouldered man glanced at a meter. "You took pretty near a full jolt, that time," he said. The hole in the globe was tracing an oblique course now, swinging to the center, then below.
