Nick a Tesla a vynálezy pro boj s tajným agentem – Pflugfelder "Science Bob" (2017)

WARNING: INSIDE YOU'LL FIND SPY CAMERAS, ENCRYPTION WHEELS, AND OTHER TOP SECRET GADGETS THAT YOU CAN ASSEMBLE YOURSELF! Eleven-year-old twins Nick and Tesla Holt have already thwarted the plans of kidnappers during the holidays and repelled an attack by an army of robots, so they deserve a moment of rest. However, in the third story, they discover that a spy is lurking very close to them, right in the house of their favorite (and a bit crazy) Uncle Newt. Is it a new intern helping Uncle in the lab? Or an exterminator? One of the cleaners? Or perhaps someone completely different? To uncover the mysterious agent, Nick and Tesla must create a series of incredible gadgets from encryption wheels and fingerprint kits to a hidden camera and a thief detection device. Instructions for making them can be found in this book, so you can easily assemble them yourself! Bob "The Scientist" Pflugfelder teaches science at an elementary school in Newton, Massachusetts. Steve Hockensmith writes his mystery stories in Alameda, California. Together, they have written the books Nick and Tesla and the Dangerous Lab and Nick and Tesla and the Army of Rampaging Robots.
