About the book, from the publisher:
Nick and Tesla are bright 11-year-old siblings with a knack for science, electronics, and getting into trouble.--Marshal Zeringue
When their parents mysteriously vanish, they’re sent to live with their Uncle Newt, a brilliant inventor who engineers top-secret gadgets for a classified government agency. It’s not long before Nick and Tesla are embarking on adventures of their own—engineering all kinds of outrageous MacGyverish contraptions to save their skin: 9-volt burglar alarms, electromagnets, mobile tracking devices, and more. Readers are invited to join in the fun as each story contains instructions and blueprints for five different projects.
In Nick and Tesla’s Robot Army Rampage, the brother-and-sister duo unleash a swarm of battery-powered gizmos (which readers can make at home). Learning about science has never been so dangerous—or so much fun!
