The Case of the Crooked Carnival (Doyle and Fossey, Science Detectives)
Science super-sleuths Drake Doyle and Nell Fossey are back—this time in a never-before-published addition to the popular series! They’ve got an exciting collection of cases, too: Are ghosts and ghouls keeping Edgar Glum awake? Have aliens invaded Mossy Swamp? What’s the crooked game everyone’s losing at the carnival? And why is the town bridge going bananas? Kids will have fun following the clues—and learning about such real scientific principles as amplification, ecosystems, magnetic fields, and more. Plus, budding Doyles and Fosseys will find actual experiments to try!
Nell did in trying to determine the identity of the ghosts and ghouls haunting Edgar’s house. Drake and Nell’s hypothesis was simply their best guess as to what was causing the noise. It probably sounded something like this: “We believe the haunting of Edgar’s home is being caused by the amplification of sound through the old pipes. We further believe that Poe is the culprit.” Third, scientists test their hypothesis. (After all, maybe the hypothesis is correct, but maybe it isn’t. Maybe there

MATERIALS • 4-foot section of ¾-inch-diameter PVC pipe • large funnel, such as the kind used for draining the oil from a car (make sure it’s clean) • duct tape • two ¾-inch-diameter PVC elbows PROCEDURE 1. Have an adult cut the pipe into two lengths: 1 foot and 3 foot (doesn’t have to be exact). 2. Insert the pointed end of the funnel into one end of the 1-foot section of pipe. Secure
suppose,” sighed Edgar. Then, just as Drake was warming his hands near the furnace, a strange thing happened. A strand of music floated through the air like a wisp of cobweb. Drake stopped warming his hands. Nell stopped shining her flashlight around. Edgar stopped sighing. Poe snored, moaning a wee bit. And they all stared at each other (except Poe, who had his eyes closed). “Great Scott!” whispered Drake. “What is that?” whispered Nell. “It’s the ghosts,” whispered Edgar. “They’re
play-by-play. Now I ask you, if you’re sitting in the crowd, how are you able to hear the announcer?” “But—but I’ve never been to a football game.” “Answer the question, Mr. Glum,” said Drake. Edgar crumpled and put his face in his hands. “I—I don’t know!” “It’s because,” said Nell, “the announcer’s voice is amplified.” Now it was Drake’s turn to pace. “Amplification is when a sound is made louder. Even the shape of your own ears helps to amplify sound. Your outer ear funnels the sound into
quite right. “Say, isn’t the purple loosegoose growing? I mean—fast?” Sure enough, in the time it takes to say “Bob’s Your Uncle,” the purple loosegoose overwhelmed the path. There was a flash of purple, an arm here and a leg there, then the troop of Boy Scouts disappeared in a tangle of beautiful purple blossoms, to the tune of “Help! Help!” And then the video abruptly ended. Drake jumped up. “Jeepers creepers!” “Jeepers creepers is right,” said Nell. “Once purple loosegoose reaches a
