The Buoyancy Project

Putney Hicks is itching to take on her next challenge. Preparing for her school's cardboard-boat regatta, the twelve-year-old inventor hunts down ways to stop the flimsy craft from sinking into a soggy mess. But after she rescues her neighbor's dog from a rip current, the curious girl can't shake the thought that the solution is right in front of her eyes... Joined by her new canine companion and using her magical tablet as she explores an alligator-infested lagoon, Putney is dismayed when she's paired on the project with her arch-nemesis. And as they reluctantly put their heads together, she suddenly realizes that the scaly swamp predators could hold the secret to their experiment's success. Can these stubborn rivals overcome their differences and construct a winning waterproof design? is the ingenious second book in the Putney Hicks Inventor Adventures middle-grade series. If you like scientifically empowered young women, entertaining escapades, and real-life mathematical motivation, then you'll love Marsha Tuft's MacGyver-like enterprise.
